饮食诱导肥胖(DIO)

从脂肪中摄取55-60%卡路里的食物TD.06414TD.93075通常用于诱发啮齿动物肥胖。虽然与典型的人类脂肪摄入相比,这些饮食被认为是极端的,但在大多数啮齿类动物中,这些饮食能有效地启动快速增重。由于脂肪含量较高,碳水化合物的摄入空间较小,因此碳水化合物(特别是蔗糖)含量相对较低。如果你对高脂肪和高碳水化合物感兴趣,那就看看脂肪中含有40-45%卡路里的饮食(通常被称为西方饮食)。

随着脂肪水平的增加,球团的质量(耐久性)经常受到损害。一些高脂肪配方只有在非颗粒形式,或需要特定的碳水化合物,麦芽糊精,用于球团。根据使用的脂肪和碳水化合物来源,非颗粒形式可能是致密和碎屑,面团样,或糊状。虽然使用非颗粒饮食更具有挑战性,但许多研究人员仍在使用非颗粒饮食来建立饮食诱导的肥胖模型,因为这些研究人员怀疑,较软的饮食形式可能会促进肥胖的发展。

从脂肪中摄取40-45%卡路里的饮食,如TD.95217TD.88137TD.06415,和TD.08811,代表了另一种流行的饮食模式-诱发肥胖的工作。这些食物的蔗糖含量是高脂肪饮食的两倍或三倍。高水平的简单碳水化合物,如蔗糖和果糖,可能有助于促进高甘油三酯血症,胰岛素抵抗和脂肪肝。高蔗糖、高饱和或反式脂肪的饮食在肥胖和心血管领域常被称为“西方饮食”。一些“西方饮食”有进一步的修改脂肪酸剖面,甚至特定的维生素和矿物质调整,以更紧密地匹配西方饮食模式。有关特定脂肪酸的修改,请参阅脂肪/脂肪调节饮食一页。

饮食诱导糖尿病

许多用于诱导啮齿动物肥胖的饮食可以用于增强糖尿病相关表型,如胰岛素抵抗和葡萄糖不耐受。然而,空腹高血糖特征的糖尿病(葡萄糖>200 mg/dL)是罕见的饮食方法。预先喂食高脂饮食,诱导一定程度的肥胖和胰岛素抵抗,然后给予小剂量链脲佐菌素(STZ)可能是一个有效的方法,如果公开高血糖是需要。

成分匹配的低脂DIO控制饮食

除了不同类型的碳水化合物外,还有许多不同水平和类型的脂肪,从蔗糖(高精制,简单消化)到玉米淀粉(精制,但更复杂),再到抗性淀粉(精制,但不能完全消化)。一个非常基本的净化控制饮食将是AIN-93M (TD.94048) 或AIN-93g(TD.94045)AIN-93日粮中蔗糖含量在10%左右,脂肪来源于具有健康脂肪酸的大豆油。更多的控制特定DIO饮食的例子可以在上表中找到。

许多研究人员选择将高脂肪喂养的动物与食用天然成分谷物的动物(也称为标准饮食或周食)进行比较。这些饮食在营养来源和水平以及非营养因素(如植酸盐或植物雌激素)存在的情况下存在差异。根据您的主要比较,它可能适合作为您的对照/参考组谷物基础的饮食。然而,这样的比较限制了对饮食模式和特定饮食成分的推断。

Diet induced obesity | Envigo

Purified high fat diets used to induce obesity and obesity-related complications such as diabetes and metabolic syndrome typically have 40-60% of energy derived from fat. The diet tables below summarize relevant diet features for several Teklad custom research diets commonly used in rodent models.

Teklad also creates high-fat diets for other species, including pigs, primates, and dogs. Contact us to discuss the use of these diets or one that better meets your needs.

Diets for diet-induced obesity (DIO)

Diets with 55-60% of calories from fat like TD.06414 and TD.93075 are commonly used for inducing obesity in rodents. While considered extreme compared to typical human fat consumption, these diets are effective in initiating rapid weight gain in most rodents. With higher fat content there is less room for carbohydrate, thus the carbohydrate (particularly sucrose) amount is relatively low compared to other obesity inducing diets. If you are interested in high fat and high carbohydrate, look at diets with 40-45% of calories from fat (often referred to as western diets).

As the fat level increases, pellet quality (durability) is often compromised. Some higher fat formulas are available only in non-pelleted form or require specific carbohydrate, maltodextrin, for pelleting. Depending on the fat and carbohydrate sources used, the non-pelleted form could be dense and crumbly, dough-like, or paste-like. Though a little more challenging to work with, non-pelleted diet is still used by many researchers for diet-induced obesity models as these researchers suspect the softer form may enhance obesity development.

Diets with 40-45% of calories from fat, like TD.95217TD.88137TD.06415, and TD.08811, represent another popular diet pattern for diet-induced obesity work. These diets have double or triple the amount of sucrose found in higher fat diets. High levels of simple carbohydrate like sucrose and fructose may help to promote hypertriglyceridemia, insulin resistance, and fatty liver. Diets with a pattern of high sucrose and high saturated or trans fat are often referred to as “Western Diets” in obesity and cardiovascular fields. Some “Western Diets” have further modifications to the fatty acid profile or even specific vitamin and minerals adjustments to be even more closely matched to a Western Diet pattern. For specific fatty acid modifications, see examples on our fat/lipid adjusted diets page.

Diets for diet-induced diabetes

Many of the same diets used for inducing obesity in rodents can be used to enhance diabetes related phenotypes like insulin resistance and glucose intolerance. However, fasting hyperglycemia characteristic of diabetes (glucose > 200 mg/dL) is uncommon with a diet only approach. Pre-feeding a high fat diet to induce a certain level of obesity and insulin resistance and then giving low-dose streptozotocin (STZ) may be an effective approach if overt hyperglycemia is desired.

Ingredient matched, low-fat DIO control diets

There are many options with different levels and types of fat in addition to different types of carbohydrate ranging from sucrose (highly refined, simple digestion) to corn starch (refined, but more complex) to resistant starch (refined, but not fully digestible). A very basic purified control diet would be AIN-93M (TD.94048) or AIN-93G (TD.94045). AIN-93 diets have a moderate amount of sucrose at ~10%, and fat is from soybean oil with a healthy fatty acid profile. Additional examples of controls for specific DIO diets can be found in the above tables.

Many researchers choose to compare their high fat fed animals to animals fed a natural ingredient, grain-based diet (also referred to as standard diets or chow). These diets differ in the source and level of nutrients as well as in the presence of non-nutritive factors (such as phytates or phytoestrogens). Depending on what your main comparisons are, it may be suitable to have a grain-based diet as your control/reference group. However, making such comparisons limits inferences to dietary patterns versus a specific dietary component.

Basal mixes

Basal mixes

You may want to add some specific ingredients in your own facility. In that case, Envigo provides basal mixes that are, by design, a starting point for additional inclusions. When you choose a basal mix diet, you simply add any ingredient(s) in a specific proportion that your require. The nutrient levels in our basal mix are adjusted to account for the dilution of the added ingredient(s), so that the final complete diet contains the desired nutrient levels.

  • TD.00235       Basal mix (93%); AIN-93G without fat
  • TD.88232       Basal mix (without 20% Oil)

Here are some examples of how a basal mix could be helpful to you:

  • Leave all or a portion of the fat source out. The end user can add various fats and make multiple diets from one basal mix
  • Make fresh diet as needed for an unstable, hazardous, or limited supply ingredient
  • Add a different vitamin or mineral mix to the same basal mix to create a series of vitamin or mineral adjusted diets

If proper mixing equipment is available, and you have the capability to feed powder diet, basal mixes offer flexibility and economy.

NaCl adjusted (natural ingredient)

NaCl adjusted (natural ingredient)

The sodium content of natural ingredients such as corn, wheat, and soybean meal is low. Thus, these ingredients can be used to create a base diet that is sodium deficient. To this base diet, various amounts of sodium chloride salt (NaCl) can be added, and other ingredients adjusted slightly to maintain a relatively constant nutrient profile (with the exception of sodium and chloride).

Below are examples from a popular series of adjusted NaCl diets. Contact us for more information.

Formula examples

* When added to natural ingredient diets, these water soluble food dyes offer a slight color tint. More intense color can be achieved at higher inclusion rates.

Ask a nutritionist about additional salt concentrations or color options.

These diets are grain-based, with no animal derived ingredients, and have a background sodium content of approx. 0.01-0.02% and a background chloride content of approx. 0.06-0.07%. The selected nutrient content of the diets are as follows: approximately 19% protein, 5% fat, 3% crude fiber, 0.86% Ca, 0.64% P, 0.72% K, and 0.15% Mg.

NaCl adjusted diets are often fed to dahl salt-sensitive/resistant (rapp) inbred rats. These rats are maintained on Teklad traditional diet 7034 (0.12% NaCl) within maximum security production facilities.

Formula examples:

  • TD.80396       Iron deficient diet
  • TD.85419       Zinc deficient diet
  • TD.88239       Potassium deficient diet
  • TD.95027       Low calcium diet (0.4% P)
  • TD.96348       Diet (20% lactose, 2% Ca, 1.25% P)
  • TD.92163       Selenium deficient diet
  • TD.95125       Iodine deficient (0.15% PTU)

Unique protein ingredients may be necessary to minimize background levels of certain minerals. Other steps taken to minimize background mineral contamination include the use of reagent grade minerals when necessary or omission of certain ingredients. Specialized mineral premixes may be used in these diets, or minerals are added individually to the diet in order to control the level of specific minerals.

With the exception of sodium, it is necessary to use refined ingredients to achieve the lowest possible levels of minerals in a diet.

From this mineral deficient base, various levels of minerals can be added back. Some formulas adjust multiple minerals, and other related nutrients.

Contact us to discuss other possibilities for the minerals listed above, and for those minerals not listed here.

Protein adjusted diets

Protein adjusted diets

A few protein adjusted formulas are shown below. Please contact us for additional formulas of this nature or for more information about altering the protein type or content of a diet.

Formula examples:

These diet examples are from a series of diets with the following features: casein-based, isocaloric (3.8 kcal/g) and matched for fat (5.5%), calcium (0.7%), and phosphorus (0.54%). There are other diets available from this series of diets, as well as other unique protein adjusted diets.

Casein is the most widely used refined protein source, but it is also possible to use other refined protein sources, such as “vitamin-free” test casein (alcohol extracted), lactalbumin, isolated soy protein, and egg white solids. These particular protein sources are usually used to achieve a specific research objective, rather than for routine use. For instance, vitamin-free test casein is most appropriately used in vitamin deficient diets, and egg white solids is most suitable for zinc or biotin deficient diets.

Adjusted protein diets usually range from “protein-free” (trace) to 60% protein, depending on the research.

Vitamin adjusted diets

Vitamin adjusted diets

A few vitamin adjusted formulas are shown below. Please contact us for additional formulas of this nature or for more information about altering the vitamin profile of a diet, and please read below to learn more.

Formula Examples:

Most vitamin deficient diets use vitamin-free test casein (VFT casein) as the protein source. VFT casein is casein that has been extracted with denatured alcohol to reduce the fat content from about 1% to 0.1%. In the process the content of a number of vitamins (present at low or trace levels in casein) is further reduced, making this an ideal protein source for these types of diets. Envigo produces our own VFT in-house, and we also offer this as an ingredient for those mixing their own diets.

From this vitamin deficient base, various levels of vitamins can be added back. Many formulas adjust multiple vitamins, and other nutrients.

If use of an intact protein source is not advisable, an amino acid defined diet can be used.

Contact us for other formula examples or to discuss your specific needs.

Harlan Teklad动物饲料Amino acid defined

上海金畔生物科技有限公司代理Harlan Teklad动物饲料全线产品,欢迎访问Harlan Teklad动物饲料官网了解更多信息。

Amino acid defined

Amino acid defined

A few amino acid defined formulas are shown below. This type of diet is used when a diet needs to be deficient in one or more amino acids, or adjustments need to be made to specific amino acid levels.

Formula examples:

  • TD.99366       Amino acid diet
  • TD.90262       Methionine and choline deficient diet
  • TD.00434       Folic acid deficient diet
  • TD.99386       No lysine AA diet

Sometimes this type of diet is used to further reduce the background level of certain vitamins that are found in protein sources such as casein or vitamin-free (alcohol extracted) casein. Some folic acid deficient diets utilize this approach.

The amino acid profile for most amino acid defined diets is based on work by Harper and Rogers (J. Nutr. (1965) 87:267-276) and is not representative of the amino acid profile of an intact protein source such as casein. Other amino acid profiles can be specified. When an amino acid(s) is removed or reduced, isonitrogenous adjustment can be made if required.

Please email us at askanutritionist@envigo.com for additional formulas of this nature or for more information about altering the amino acid profile of a diet.

7092-7097 Teklad corncob bedding

7092-7097 Teklad corncob bedding

The raw stock for our corncob bedding products is 100% corncob. No other components or additives are used. The 1/4″ (7097) and 1/8″ (7092) products are produced from only the woody-ring portion of the corn cob, and the pelleted corncob is produced from the pith and chaff (beeswing) portions.

As the raw stock corncobs are introduced to the plant, they pass through a hammermill that produces corncob fractions. The corncob fractions are then heat-dried. The drying process utilizes a rotary dryer systemthat heats the corncob fractions to approximately 200 degrees fahrenheit for two to three minutes. An aspiration process separates the woody-ring portion of the corncob from the pith and chaff portions. Smaller fractions/particles are produced by rollermill and hammermill processes. The particles are then sized and separated through a sifting process which utilizes screens conforming to U.S. standards. The particles pass through a final aspiration process to remove any remaining dust and aspiration process to remove any remaining dust and are then placed in overhead storage until packaged. The pith and chaff portions are processed through a pellet mill to produce the pelleted corncob product. Plant operating procedures require a minimum testing frequency of twice per shift for measuring moisture content and particle size distribution.

Listed below is information on average particle size and absorption rates.

  • 7092 — 1/8″ corn cobs, 40 lbs.
  • 7092A, Autoclavable — 1/8″, corn cobs, 40 lbs.

Harlan Teklad动物饲料NAFLD and NASH

上海金畔生物科技有限公司代理Harlan Teklad动物饲料全线产品,欢迎访问Harlan Teklad动物饲料官网了解更多信息。

NAFLD and NASH

NAFLD and NASH

Dietary methods to induce NAFLD/NASH in rodents can be split into two common categories:

  • diets fed for longer periods of time to induce obesity, metabolic syndrome, and mild NASH or
  • diets fed for short periods of time to induce hepatic features of severe NASH without inducing obesity or insulin resistance

This page provides further information on dietary methods to induce NAFLD/NASH. We’ve also prepared a downloadable NASH/NAFLD mini paper.

The tables below highlight diet options from both of the above categories. For more complete descriptions of NAFLD/NASH models see the drop down menus that follow the tables.

    Diets inducing obesity, metabolic syndrome and mild NAFLD/NASH

  • Western and Fast Food diets with milkfat and cholesterol

    Western or fast food style diets fed to induce NASH with metabolic syndrome contain 40 – 45% kcal from milkfat (a fat source high in palmitate) with added cholesterol (0.15 – 2%) and are high in sucrose (>30%). Dietary palmitate and cholesterol have both previously been associated with the progression from simple steatosis to NASH.

    Examples:

     

    Research use:

    These diets can induce obesity, metabolic syndrome, and simple steatosis within nine weeks of feeding. Increased hepatic inflammation has been observed after 12 weeks of feeding. NASH typically requires longer feeding with fibrosis developing within nine months and late stage fibrosis including hepatic ballooning occurring after 14 – 20 months of feeding. Increasing dietary sucrose (~41%) and cholesterol (~1.25%) accelerates the NASH phenotype with steatosis, inflammation and hepatocyte ballooning observed within 12 weeks. In addition to feeding a high fat diet, providing a glucose/fructose mixture in the drinking water may further promote NASH development.

  • The ALIOS model: western diet with trans-fat

    The American Lifestyle-Induced Obesity Syndrome (ALIOS) model involves feeding the “American fast food” diet high in trans-fats and sugar. Dietary trans-fats from hydrogenated vegetable shortening (HVO) are associated with increased insulin resistance and hepatic inflammation in rodent NASH models. In addition to diet, a glucose/fructose solution is added to the drinking water and sedentary behavior promoted by removing the overhead cage feeders in this model.

    Examples:

     

    Research use:

    The ALIOS model develops obesity with insulin resistance, elevated ALT levels, and steatosis within 16 weeks. Increased inflammation and early development of fibrosis have been observed at 6 months. Severe steatosis with fibrosis and inflammation develops within 12 months of feeding with 50% of the mice reportedly developing hepatic neoplasms. Adding cholesterol (0.2%) to the American Fast Food diet may accelerate NASH phenotype development.

  • FPC diet: fructose, palmitate, cholesterol and trans-fat diet

    The Fructose, Palmitate, Cholesterol and Trans-Fat (FPC) diet is a recent NASH diet that includes Western and ALIOS model diets to achieve both metabolic and hepatic NASH features within an accelerated time frame. Key features of the FPC diet include 1) a lower Met content than typical rodent diets by decreasing total protein without supplementing sulfur amino acids; 2) choline supplementation is lower than typical but is not considered deficient; 3) high in sucrose (~34% by weight); 4) 1.25% cholesterol; 5) 52% kcal from fat with fat sources including milkfat fat, palmitic acid and hydrogenated vegetable shortening to provide trans-fats. Like the ALIOS model, the FPC model also provides a glucose/fructose solution to the drinking water.

    Examples:

    • TD.160785 52 kcal/Fat Diet (C16:0, HVO, AMF, Choline/Met)

     

    Research use:

    Male C57BL/6J mice fed the FPC diet and provided a glucose/fructose drinking solution developed insulin resistance and NAFLD with inflammation, hepatocyte death, and fibrosis within 16 weeks.

  • High fat diets

    Common diets to induce obesity (DIO) can be fed to induce uncomplicated NAFLD. These high fat diets typically contain 40–60% kcal from fat without supplemented cholesterol or cholate. Simple sugars such as sucrose or fructose can also be supplemented via diet or water to progress the fatty liver phenotype. Diets can be in pellet or powder/dough form depending on the formula. Some models require limited physical activity and in those cases diets can be fed inside the cage. For more information see our Diet Induced Obesity page.

    Examples:

     

    Research use:

    In susceptible rodent models, high fat diets are commonly used to induce NAFLD with obesity and insulin resistance common metabolic features associated with NASH in humans. However, the degree of NASH pathology (steatosis, inflammation, and fibrosis) is limited or mild and varies depending on the animal model, length of feeding, and dietary components.

  • Diets to induce severe hepatic NAFLD/NASH without obesity or metabolic

  • Atherogenic diets high in fat, cholesterol, and cholate

    Originally formulated to induce mild atherosclerosis in wild-type rodents, high fat diets containing added cholesterol (1 – 1.25%) and cholate (0.5% as sodium cholate or cholic acid) have also been useful in inducing NASH. This diet option includes purified “Western” style diets with increased cholesterol and cholate and also hybrid diets. Hybrid diets were originally developed by Beverly Paigen and colleagues by mixing a natural ingredient mouse diet in a 3:1 ratio with a concentrated purified diet (containing 5% cholesterol and 2% sodium cholate) resulting in a diet containing ~15.8% fat, 1.25% cholesterol, and 0.5% sodium cholate. Although a less refined approach, the hybrid diet is associated with increased gallstone formation and liver damage as compared to similar purified diets.

    Examples:

     

    Research use:

    Atherogenic diets are able to induce varied degrees of NASH with increased hepatic inflammation with early fibrosis observed after ten weeks of feeding. However, the metabolic profile typical in human NASH (obesity with insulin resistance) is not recapitulated in this model with animals typically maintaining similar body weights as control fed groups without the development of metabolic syndrome.

  • Methionine/choline deficient (MCD) diets

    Methionine and choline deficient (MCD) diets are amino acid defined rodent diets deficient in methionine and choline, high in sucrose (>40% by weight) with ~10% corn oil by weight. Methionine and choline deficiency decreases fat oxidation and export of fat from the liver. Dietary sucrose is necessary for hepatic lipid accumulation and oxidation. The polyunsaturated fat in corn oil promotes hepatic lipid oxidation.

    Example:

     

    Control:

     

    Research use:

    Steatosis, increased serum alanine aminotransferase (ALT), inflammation, and hepatic fat oxidation has been observed within three weeks of feeding the MCD diet with fibrosis development after six weeks. This dietary model does not produce metabolic syndrome (an aspect of NASH in human models) and progressive weight loss (up to 40%) is associated with the MCD diet feeding.

  • Emerging NASH models

    Dietary models of NAFLD/NASH continue to evolve with the goal of more accurately recapitulating both the metabolic and hepatic symptoms of human disease. Commonly researchers are studying the synergistic effects of various NASH dietary features to accelerate progression of the model and severity of liver disease.

    A Teklad nutritionist can work with you to formulate new diets in order to investigate novel dietary models of NAFLD/NASH. Contact a nutritionist at askanutritionist@envigo.com for a diet consultation.

  • Control diets

    The choice of control diet is dependent on the specific research goal. Many researchers choose to compare their NAFLD/NASH diet-fed animals to animals fed a natural ingredient, grain-based diet (also referred to as standard diet or chow). These diets differ in the source and level of nutrients as well as in the presence of non-nutritive factors (such as phytates or phytoestrogens).

    Depending on what your main comparisons are, it may be suitable to have a grain-based diet as your control/reference group. However, making such comparisons limits inferences to dietary patterns versus a specific dietary component. In some cases, such as those studies feeding amino acid defined diets like the MCD model, a matched control diet is recommended given the very different formulations and protein sources of grain-based diets.

    When making inferences about specific nutrients within the diet an ingredient matched, low fat control diet may be necessary. There are many options with different levels and types of fat in addition to different types of carbohydrate ranging from sucrose (highly refined and digestible) to corn starch (refined, but more complex) to resistant starch (refined, but not fully digestible).

    A very basic purified control diet would be AIN-93M TD.94048 or AIN-93G TD.94045 . AIN-93 diets have a moderate amount of sucrose at ~10% with fat from soybean oil providing a healthy fatty acid profile. Learn more about AIN diet formulas.

    Contact a nutritionist for an additional information and control diet recommendations.

Need more information? A Teklad nutritionist will work with you to determine if existing diets will meet your needs or formulate new diets to help you investigate novel dietary models of NAFLD/NASH. Contact us for a diet consultation.

Fat/lipid adjusted

Fat/lipid adjusted

There are numerous possibilities in adjusting both the level and source of fat in a diet. If your primary interest is inducing atherosclerosis or obesity, additional information can be found on our Teklad atherogenic and diet induced obesity (DIO) diet pages. Depending on your research goals and level of desired fat supplementation, fats can be added to a standard natural ingredient diet or a purified diet.

Purified ingredients are refined to the point of chemical simplicity and allow for extreme fat levels such as no fat diet TD.03314 or very high fat ketogenic diet TD.96355 . Unless adjustments are made to the level of fiber, diets with high fat levels will have a greater caloric density since fat contains 9 kcal/g versus 4 kcal/g for carbohydrate or protein. Animals are good at regulating caloric intake, therefore it is common to adjust other nutrients (vitamins, minerals, protein) relative to energy content to account for differences in feed intake.

Specific fats can be utilized as in this essential fatty acid deficient diet TD.84224 or to provide high levels of omega-3 polyunsaturated fat from flaxseed or fish oil. Normally, 1-2% fat from plant sources like corn or soybean oil will supply sufficient levels of essential fatty acids. Additional fat provides energy and can influence palatability due to effects on taste and texture of the diet.

Mixtures of fats can be used to mimic a Western or Mediterranean diet fatty acid profile. Contact us for a table comparing the fatty acid composition of several stocked fat sources (solid fats, oils).

We also commonly work with customer supplied oils and purified fatty acids such as DHA and EPA. If you prefer to mix fat sources in your lab, ask about a basal mix. Basal mixes are supplied in powder form and often allow you to use one diet mix for creating several different diets.

If fat stability is a concern, contact a nutritionist to discuss options for diet drying, vacuum packaging, and synthetic antioxidant supplementation.

Harlan Teklad动物饲料Rabbit, swine and other species diets

上海金畔生物科技有限公司代理Harlan Teklad动物饲料全线产品,欢迎访问Harlan Teklad动物饲料官网了解更多信息。

Rabbit, swine and other species

Rabbit, swine and other species diets

The most common custom rabbit diets are those with a standard diet base and added cholesterol. Typically, the added cholesterol ranges from 0.25% to two percent. Additional fat can also be a feature of these formulas. To preserve pellet quality we recommend no more than six percent additional fat. Added fat is most often supplied as peanut oil, corn oil, coconut oil, or a combination. We recommend the Teklad base diets 2030 or 2031.

Rabbits do not readily consume purified diet. When specific nutrient manipulations are necessary, hybrid diets or at least some alfalfa meal inclusion is recommended. Contact us for formula examples or to discuss your specific needs.

Most often, customized diets for swine feature natural ingredients with added fat and cholesterol. Here are three variations on this theme:

  • TD.92033 Swine diet (15% lard, 1.2% cholesterol)
  • TD.92052 Swine diet (15% lard, 1.5% cholesterol)
  • TD.93296 Swine diet (15% lard, two perecent cholesterol)

We recommend these diets in meal/powder form, as pellets are not very durable. Other natural ingredient and purified diets with various nutrient manipulations are available. Contact us for further information.

The most common custom Guinea pig diets are those with a standard diet base (such as Teklad 2040 or 2041) and added cholesterol.

Guinea pigs do not readily consume purified diets, so when specific nutrient manipulations are necessary, hybrid diets (mixture of refined and natural ingredients) are recommended. At the very least it is advisable to retain some alfalfa meal in the diet. Contact us for further information.

Most times, diets that are developed for mice and rats are suitable for hamsters and gerbils, and vice versa. We may advise increasing specific nutrients in a purified diet for hamsters and gerbils. Contact us for further information.

Depending on the focus of your research, customized diet for non-human primates can contain natural ingredients, refined ingredients, or a mixture of both. Custom diets for primates often feature adjustments in fat type, fat level, and cholesterol. Contact us for further information.

Brexit FAQs

Brexit FAQs

Envigo is continuously monitoring, preparing and updating its guidance to customers as we approach the key dates of the Article 50 separation of the United Kingdom from the European Union (aka “Brexit”). Envigo established a Brexit task force consisting of senior leadership from key areas of our business to ensure ongoing business continuity for both Envigo and its customers.

This task force continues to meet regularly in order to prepare and implement business process plans and resourcing to anticipate and minimize the impact of Brexit on our business. The following FAQs have been prepared as current guidance and is continually updated as the position between the British Government and the EU develops.

Brexit is a priority for Envigo and if you have any concern, please contact us at brexit@envigo.com.

Download the Brexit FAQs .

    Trade (Import / Export / Supply Chain)

  • Will there be tariffs applied to animal costs under WTO?

    Laboratory animals currently have no tax added for movement in to the EU and across the EU, this position will remain the same under WTO

    Prices for 2021 are being reviewed as normal and will be confirmed in due course.

  • Will there be changes in documentation needed for movements of animals in or out of the UK?

    Import to UK Changes:
    Envigo’s current understanding is that there will be limited change in terms of documentation required. 

    DEFRA have now confirmed that no additional vet checks on arrival will be required

    Also customers can use the AHPA License for the import into the UK of live rodents or lagomorphs for research. Our Customer Services team are talking to the relevant customers and can advise any new customers as required

    Our Customer Services team is working directly with customers to make the necessary changes to Incoterms

    Export from UK Changes:
    Envigo understands that the export documentation will need to be agreed with the EU and may require an additional licence per shipment. This may take an additional time to secure plus an additional vet check may be required prior to shipment. We are working with EU groups to clarify this position and will update customers once a firm position is confirmed.

    Documentation:
    Exact documentation requirements are to be clarified, please contact your customer services representative if you have immediate concerns.

  • Will there be any other impact on the movement of animals in and out of the UK?

    The main impact we currently predict is additional delays in shipments due to:

    Export license requests may add time to the process from PO to shipment for small animals being shipped from the UK to the EU. Vet checks might be required at Border Inspection Posts at the airport of arrival.

    Additional CITES might be required and thus may add additional time for shipments of animals requiring to travel under CITES from the EU to the UK.

  • Will there be tariffs on any other goods imported in and out of the UK under WTO?

    Under WTO terms the Envigo team have assessed that there will be additional tariffs on certain goods including our Teklad diet shipments into the UK. Additional costs are being assessed and any cost impact to clients will be conveyed to customers via our commercial sales team as soon as possible.

  • Has Envigo ensured that its supply chain for its Operations are ready for the change on 1st Jan?

    Envigo’s Procurement team continues to work with it’s key suppliers in the UK to ensure that supply chains are secure for the post Brexit period. The team are encouraging suppliers to ensure that they have sufficient stock to cover any transition period at the beginning of January.

  • What will the impact be on the movement of biological products (UK to customer EU and EU to UK)?

    We are working with the governmental authorities in the relevant countries together with our international couriers to determine labelling / commercial invoice / payment of VAT / export license & vet check requirements. We will update all parties once further clarity is obtained. We are sure that this will be determined to ensure continuity of these services as we transition to the post Brexit position.

  • Does Envigo think movement of animals in and out of the UK will have the changes in place ready for 1st Jan?

    Envigo recommends that its clients do not request animals deliveries in or out of the UK during the first two weeks of January in order to ensure that all changes at borders and documentation are in place. If there is a requirement for a shipment early in January we would request that you contact your customer services representative as early as possible in December order that the necessary plans can be put in place.

  • Are there any specific concerns in relation to shipments to Ireland?

    The changes in movement of goods from UK to both Northern and Southern Ireland is still unknown – further clarification will be provided when we have more information.

    Talent

  • What proportion of Envigo’s UK employees are EU nationals?

    Less than 6% of Envigo’s UK employees are EU nationals. We have worked with all of these employees to ensure they have the relevant rights to live / work in the UK or EU as appropriate

  • What is Envigo’s expectation of the impact of immigration challenges to staffing your UK-based operation?

    This is not expected to have significant impact as Envigo has separate distribution centres in both the UK and EU to enable us to continue to operate under the most favourable trading environment for our customers regardless of trading arrangements between the UK and the EU, or between the UK, EU and the rest of the world. We are committed to recruiting and retaining the best people and to pursue our mission to be the best company to work with and the best company to work for.

    Financial

  • What will be the impact on Envigo’s finances?

    Envigo is financially stable and resilient: Though there might be minor changes arising from the Brexit transition, we believe that there will not be any significant adverse impact to the business and we will continue to invest in world-class operations and innovation post Brexit.

  • Impact of exchange rate movements on costs, profitability and competitive position

    Exchange rate movements are an inevitable fact of the business environment and occur because of numerous factors including, inflation, government fiscal policy, real gross domestic product GDP and expectations around future economic performance and the impact of speculative currency investment. In this regard, they are not deemed to be solely a Brexit specific issue. Exchange rate risk is mitigated by Envigo due it being an international business, which has regional operational centres in proximity to the customer base incurring costs in the same currency of sale.

    Data Protection/GDPR

  • What is will be the status of the General Data Protection Regulation (2016/679) (GDPR) after the transition period.

    The UK is committed to maintaining the high standards of the GDPR and the government plans to incorporate it via the European Union (Withdrawal) Act 2018 into UK law alongside the Data Protection Act 2018, at the end of the transition period.

  • What safeguards will be in place for 1. UK to EEA Personal Data flows; 2. EEA to UK Personal Data flows; and, 3. UK sharing data outside the EEA after the transition period?
    1. The UK government has stated that transfers of Personal Data to the EEA will not be restricted and that no additional steps are necessary at this time.
    2. The European Commission is presently deliberating on an adequacy decision under Article 45(3) of the GDPR which would enable the transfer of personal data from EEA states to the UK without requiring any further safeguards. Pending such an adequacy decision or in the absence thereof, Envigo is putting in place approved safeguards in the form of standard contractual clauses.
    3. Rules for sharing data with countries outside the EEA will remain similar.The UK government has confirmed that there will be transitional provisions to recognise existing EU adequacy decisions and EU-approved transfers safeguards.

    Other

  • What Brexit scenario is Envigo planning for?

    At this stage Envigo is planning for a “no-deal” scenario and have put the necessary actions in place to manage its business on this basis

  • Has Envigo undertaken an internal assessment of what impact Brexit will have on customer’s business operations?

    Yes, Envigo continues to assess the potential impact of Brexit on both our customers and suppliers. In response to Brexit we have:

    • Our internal task force is continuously assessing the overall business risks
    • Developing a range of contingency plans to mitigate the effects
    • Envigo are taking a leading role and working with various industry associations. ABPI, BIA, EARA, and UK government departments (e.g. DEFRA, Home office, Her Majesty’s Revenue and Customs (HMRC)). At this stage there are still uncertainties on specific issues e.g. CITES and as such there are still risks that we continue to try and mitigate against. As a result, we would recommend that cross border shipment in the first two weeks of January be avoided.
  • Have you developed a plan to mitigate the Brexit risks you have identified?

    Yes, and are already initiating action and contingency plans to address potential impacts on our business based upon our current understanding.

  • Does Envigo review and adjust plans based on Brexit negotiations and wider external events?

    Yes, our internal task force is continuously assessing the overall business risks, to ensure the plans are both relevant and appropriate to the current political situation.

  • Whom may we contact to follow up on the responses to Brexit mitigation plans?

    An e-mail address has been established: brexit@envigo.com. This is available for use to allow any specific follow up questions to be raised that you might have in relation to Envigo’s Brexit mitigation plans.

For example, we may aggregate your Usage Data to calculate the percentage of users accessing a specific website feature. However, if we combine or connect Aggregated Data with your personal data so that it can directly or indirectly identify you, we treat the combined data as personal data which will be used in accordance with this Privacy Policy.

If you fail to provide personal data

Where we need to collect personal data by law, or under the terms of a contract we have with you and you fail to provide that data when requested, we may not be able to perform the contract we have or are trying to enter into with you (for example, to provide you with goods or services). In this case, we may have to cancel a product or service you have with us but we will notify you if this is the case at the time.

2. How is your personal data collected?

Promotional offers from us

We may use your Identity, Contact, Technical, Usage and Profile Data to form a view on what we think you may want or need, or what may be of interest to you. This is how we decide which products, services and offers may be relevant for you.

You will receive marketing communications from us if you have requested information from us or purchased goods or services from us or if you provided us with your details when you entered a competition, registered for a promotion or for an event and, in each case, you have not opted out of receiving that marketing.

Third-party marketing

Opting out

You can ask us to stop sending you marketing messages at any time via the contact preference center, available in all email communications, or by contacting us at any time.

Where you opt out of receiving these marketing messages, this will not apply to personal data provided to us as a result of a product/service purchase, product/service experience or other transactions.

Cookies

You can set your browser to refuse all, or to alert you when websites set or access cookies. If you disable or refuse cookies, please note that some parts of this website may become inaccessible or not function properly. For more information about the cookies we use, please see our cookie statement.

Change of purpose

We will only use your personal data for the purposes for which we collected it, unless we reasonably consider that we need to use it for another reason and that reason is compatible with the original purpose. If we need to use your personal data for an unrelated purpose, we will notify you and we will explain the legal basis which allows us to do so.

Please note that we may process your personal data without your knowledge or consent, in compliance with the above rules, where this is required or permitted by law.

4. Disclosures of your personal data

We may have to share your personal data with the parties set out below for the purposes set out in the table in paragraph 3 above.

  • Internal Third Parties as set out in the Glossary below.
  • External Third Parties as set out in the Glossary below.
  • Third parties to whom we may choose to sell, transfer, or merge parts of our business or our assets. Alternatively, we may seek to acquire other businesses or merge with them. If a change happens to our business, then the new owners may use your personal data in the same way as set out in this privacy notice.

We require all third parties to respect the security of your personal data and to treat it in accordance with the law. We do not allow our third-party service providers to use your personal data for their own purposes and only permit them to process your personal data for specified purposes and in accordance with our instructions.

5. International transfers

We share your personal data within the Envigo Group. This will involve transferring your data outside the European Economic Area (EEA).

Some of our external third parties are based outside the European Economic Area (EEA) so their processing of your personal data will involve a transfer of data outside the EEA.

Whenever we transfer your personal data out of the EEA, we ensure a similar degree of protection is afforded to it by ensuring at least one of the following safeguards is implemented.

  • We will only transfer your personal data to countries that have been deemed to provide an adequate level of protection for personal data by the European Commission.
  • Where we use certain service providers, we may use specific contracts approved by the European Commission which give personal data the same protection it has in Europe.
  • Where we use providers based in the US, we may transfer data to them if they are part of the Privacy Shield (to the extent that it continues to provide adequate safeguards) which requires them to provide similar protection to personal data shared between the Europe and the US. For further details, see European Commission: EU-US Privacy Shield.

6. Data security

We have put in place appropriate security measures to prevent your personal data from being accidentally lost, used or accessed in an unauthorized way, altered or disclosed. In addition, we limit access to your personal data to those employees, agents, contractors and other third parties who have a business need to know. They will only process your personal data on our instructions and they are subject to a duty of confidentiality.

We have put in place procedures to deal with any suspected personal data breach and will notify you and any applicable regulator of a breach where we are legally required to do so.

7. Data retention

How long will you use my personal data for?

We will only retain your personal data for as long as necessary to fulfil the purposes we collected it for, including for the purposes of satisfying any legal, accounting, or reporting requirements.

To determine the appropriate retention period for personal data, we consider the amount, nature, and sensitivity of the personal data, the potential risk of harm from unauthorised use or disclosure of your personal data, the purposes for which we process your personal data and whether we can achieve those purposes through other means, and the applicable legal requirements.

In some circumstances you can ask us to delete your data: see Request erasure below for further information.

In some circumstances we may anonymise your personal data (so that it can no longer be associated with you) for research or statistical purposes in which case we may use this information indefinitely without further notice to you.

8. Your legal rights

Under certain circumstances, you have rights under data protection laws in relation to your personal data. You may be entitled to:

  • Request access to your personal data.
  • Request correction of your personal data.
  • Request erasure of your personal data.
  • Object to processing of your personal data.
  • Request restriction of processing your personal data.
  • Request transfer of your personal data.
  • Right to withdraw consent.

You also have the right to complain to your local data protection authority if your privacy rights are violated, or if you have suffered as a result of unlawful processing of your personal information. We would however welcome the opportunity to resolve any issue that you have.

If you wish to exercise any of the rights set out above, please contact us.

No fee usually required

You will not have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee if your request is clearly unfounded, repetitive or excessive. Alternatively, we may refuse to comply with your request in these circumstances.

What we may need from you

We may need to request specific information from you to help us confirm your identity and ensure your right to access your personal data (or to exercise any of your other rights). This is a security measure to ensure that personal data is not disclosed to any person who has no right to receive it. We may also contact you to ask you for further information in relation to your request to speed up our response.

Time limit to respond

We try to respond to all legitimate requests within one month. Occasionally it may take us longer than a month if your request is particularly complex or you have made a number of requests. In this case, we will notify you and keep you updated.

9. Glossary

LAWFUL BASIS

Legitimate Interest means the interest of our business in conducting and managing our business to enable us to give you the best service/product and the best and most secure experience. We make sure we consider and balance any potential impact on you (both positive and negative) and your rights before we process your personal data for our legitimate interests. We do not use your personal data for activities where our interests are overridden by the impact on you (unless we have your consent or are otherwise required or permitted to by law). You can obtain further information about how we assess our legitimate interests against any potential impact on you in respect of specific activities by contacting us.

Performance of Contract means processing your data where it is necessary for the performance of a contract to which you are a party or to take steps at your request before entering into such a contract.

Comply with a legal or regulatory obligation means processing your personal data where it is necessary for compliance with a legal or regulatory obligation that we are subject to.

THIRD PARTIES

Internal Third Parties

Other companies in the Envigo Group acting as joint controllers or processors and who are based in the USA, Europe and ROW and provide products and services and IT and system administration services and undertake leadership reporting.

External Third Parties

  • Service providers acting as processors who provide IT and system administration services.
  • Professional advisers acting as processors or joint controllers including lawyers, bankers, auditors and insurers who provide consultancy, banking, legal, insurance and accounting services.
  • HM Revenue & Customs, regulators and other authorities acting as processors or joint controllers who require reporting of processing activities in certain circumstances.

YOUR LEGAL RIGHTS

You have the right to:

Request access to your personal data (commonly known as a “data subject access request”). This enables you to receive a copy of the personal data we hold about you and to check that we are lawfully processing it.

Request correction of the personal data that we hold about you. This enables you to have any incomplete or inaccurate data we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.

Request erasure of your personal data. This enables you to ask us to delete or remove personal data where there is no good reason for us continuing to process it. You also have the right to ask us to delete or remove your personal data where you have successfully exercised your right to object to processing (see below), where we may have processed your information unlawfully or where we are required to erase your personal data to comply with local law. Note, however, that we may not always be able to comply with your request of erasure for specific legal reasons which will be notified to you, if applicable, at the time of your request.

Object to processing of your personal data where we are relying on a legitimate interest (or those of a third party) and there is something about your particular situation which makes you want to object to processing on this ground as you feel it impacts on your fundamental rights and freedoms. You also have the right to object where we are processing your personal data for direct marketing purposes. In some cases, we may demonstrate that we have compelling legitimate grounds to process your information which override your rights and freedoms.

Request restriction of processing of your personal data. This enables you to ask us to suspend the processing of your personal data in the following scenarios: (a) if you want us to establish the data’s accuracy; (b) where our use of the data is unlawful but you do not want us to erase it; (c) where you need us to hold the data even if we no longer require it as you need it to establish, exercise or defend legal claims; or (d) you have objected to our use of your data but we need to verify whether we have overriding legitimate grounds to use it.

Request the transfer of your personal data to you or to a third party. We will provide to you, or a third party you have chosen, your personal data in a structured, commonly used, machine-readable format. Note that this right only applies to automated information which you initially provided consent for us to use or where we used the information to perform a contract with you.

Withdraw consent at any time where we are relying on consent to process your personal data. However, this will not affect the lawfulness of any processing carried out before you withdraw your consent. If you withdraw your consent, we may not be able to provide certain products or services to you. We will advise you if this is the case at the time you withdraw your consent.

Customer supplied ingredients

Customizing diets for all types of research needs

Customer supplied ingredients

When your experiments require the addition or application of certain compounds to your animal research subject, you can consider adding your medications or compounds to your animal’s diet. Envigo has experience customizing diets for all types of research needs, and that includes introducing additives as a convenient way to medicate lab animals. Simply turn to one of our expert staff nutritionists to determine whether it is a viable option.

Medications or compounds supplied by your investigator are referred to as “customer supplied ingredients” or “customer reserves,” and they can be added to most diets. Generally, if the stability or activity of the compound is not compromised during manufacture or further processing such as irradiation, adding an ingredient can be a smart option for simplifying your feeding and medicating schedules. Also, the inclusion rate of any given compound is adjusted to suit your needs, and can be determined in consultation with our expert nutritional staff.

Please use the customer supplied ingredients submission form if you require the addition or application of certain compounds to your animal research subject.

Some common customer supplied compounds include:

  • Cuprizone (also now stocked)
  • Tamoxifen (also now stocked: US, EU)
  • Purified fatty acids (DHA, EPA)
  • Curcumin
  • Rosiglitazone
  • Statins
  • Antibiotics
  • Valproate
  • Piroxicam
  • Berry powders
  • Bisphenol A (BPA, in diluted form)

When adding a compound to a diet, we will work with you to be sure that it is appropriate for our diet formulation procedures and can be done safely.

  • We require a safety data sheet or other relevant safety and usage information
  • We have an obligation to maintain a safe work environment. This typically applies to drugs, experimental compounds and chemicals
  • Food products generally will not require safety information, although information about nutrient content, reason for use, etc. is helpful in the design of diets

  • Water is added as a pelleting aid. Pellets are formed under pressure but no external heat is applied
  • Sometimes the drying process can be modified if heat stability is questioned
  • It is your responsibility to determine the suitability of the compound for inclusion into a pelleted diet

  • If you require irradiation, we can customize most diets to be suitable for this sterilization process
  • Once your diet has been produced, we can send it for irradiation. The dose ranges from 20-50 kGy. Diets that are to be irradiated require an additional two weeks for shipment (four weeks total)
  • For diets that are to be irradiated, vacuum packaging may be beneficial. Both irradiation and vacuum packaging must be requested when ordering
  • We defer to you to determine the suitability of the compound for irradiation

  • Inform us on a g/kg diet or percentage basis, how much of the compound you want in the diet
  • If you need to calculate a dose based on animal body weight, we can help convert that to g/kg diet
  • Depending on the choice of base diet and the nature of the added ingredient(s), more than a ten percent dilution is generally not advisable
  • To limit differences between the control and experimental diets you may want to consider using a control diet that uses similar ingredients and has gone through the same production process

  • Send extra compound (approximately enough for one more kg than you have ordered) so that we can yield the desired amount of diet
  • If we have not received enough compound, we will use the entire amount and make as much diet as possible, unless special arrangements can be made

  • If you plan to use the compound more than once and stability with storage is not an issue, we can maintain an inventory for you and store it appropriately, per your instructions
  • Unless otherwise instructed, we will return any remaining compound with your shipment, but we do not dispose of the compound
  • If you would like your compound retained for future use, please supply us with a retention document

Isoflavone adjusted

Isoflavone adjusted

Isoflavones, a type of phytoestrogen, are found in soy protein. Most traditional standard diets have soybean meal as a major ingredient, and therefore are a significant source of isoflavones. Please refer to FAQ section for more information about phytoestrogens.

In contrast, casein-based purified diets such as AIN-76A, AIN-93G, AIN-93M, and formulas with similar ingredients, are essentially free of isoflavones. This type of diet is sometimes used for research that requires a minimal isoflavone background. This type of diet can be used as the background to which isoflavones such as genistein (supplied by the customer) can be added.

An alternative to a purified, casein-based diet is a natural ingredient diet from our global rodent diet line. Several diets in this line contain minimal isoflavone/phytoestrogen levels and are commonly used for research that requires a minimal isoflavone/phytoestrogen background. This type of diet can also be used as the background to which isoflavones such as genistein (supplied by the customer) can be added.
