Teklad diet, bedding and enrichment    Teklad laboratory animal diets   Custom research diets   NAFLD and NASH

诱导啮齿动物NAFLD/NASH的饮食方法可分为两大类:

  • 长期喂饲可诱发肥胖、代谢综合症及轻微纳什或
  • 短时间喂饲可诱发严重纳什的肝脏特征而不引起肥胖或胰岛素抵抗的饮食。

下表突出了上述两个类别的饮食选择。有关NAFLD/NASH模型的更完整描述,请参见表后面的下拉菜单。

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 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:

  • TD.88137       Adjusted Calories Diet (42% from fat)
  • TD.96121       21% MF, 1.25% Chol. Diet
  • TD.120528     42% Kcal/Fat Diet (Incr. Sucrose, 1.25% Chol.)

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 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:

  • TD.06303       22% HVO Diet
  • TD.120330     22% HVO + 0.2% Cholesterol Diet
  • TD.130885     ALIOS with Added Sugar

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.

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.

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:

  • TD.08811       45%kcal Fat Diet (21% MF, 2% SBO)
  • TD.06414       Adjusted Calories Diet (60/Fat)

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

COLLAPSE ALL TABS

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:

  • TD.02028       Atherogenic Rodent Diet
  • TD.88051       Cocoa Butter Diet and Purina Mouse Chow
  • TD.09237       15% AMF Diet (1% Chol, 0.5% NaChol)

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 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:

  • TD.90262       Methionine/Choline Deficient Diet

Control:

  • TD.94149       Amino Acid Control Diet

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.

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.

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.

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

对照日粮
控制饮食的选择取决于具体的研究目标。许多研究人员选择比较他们的NAFLD/纳什饮食喂养的动物和喂养一种天然成分的动物,谷物为基础的饮食(也称为标准饮食或周食)。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。在某些情况下,如那些研究喂食氨基酸定义的饮食,如mcd模型,建议一个匹配的对照饮食,考虑到非常不同的配方和蛋白质来源的谷物为基础的饮食。

当对饮食中的特定营养成分做出相应的推断时,低脂控制饮食可能是必要的。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(高精制和可消化)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)。

一种非常基本的纯正控制饮食将是-9300万。TD.94048或者是93g TD.94045。AIN-93日粮中含有适量的蔗糖~10%,大豆油中的脂肪提供了健康的脂肪酸谱。

Diet can be a useful tool to induce or accelerate atherosclerosis in laboratory animal models. Key dietary features used to induce atherosclerosis in rodents vary depending on the research model, desired endpoint, and length of feeding. While formulations of atherogenic diets continue to evolve, the options that are well-described in the literature are summarized below. For more information on each diet option and literature references see the expandable tabs following the diet table.

Teklad diet, bedding and enrichment + Teklad laboratory animal diets + Custom research diets + Diet ingredients

You may want to prepare your own diet at your research site or facility, and if that is the case, you depend on the ingredients being of the highest quality. Envigo can provide you with many of the same ingredients used to produce our advanced Teklad custom research diets so you can develop your own formula. And as always, our nutritional experts are here to help you make the best decisions for your ingredients and ultimate formulation.

Our ingredients

We offer several ingredients for individual sale so that you can develop your own blends.

“VFT” casein

  • “Vitamin-free” test casein (alcohol-extracted) is best suited for purified test diet formulas where fat or vitamin content needs to be precisely controlled
  • The reduced levels of many vitamins in VFT casein make it the preferred protein source for many vitamin studies. Thus, the nickname “Vitamin-free” was given to the extracted casein many years ago

Vitamin mixes

  • The common vitamin mixes shown below use sucrose or corn starch as a carrier
  • Customized vitamin mixes may use cellulose if a non-nutritive carrier is necessary
  • Vitamin mixes are formulated with a diet inclusion rate in mind. Using more or less than recommended could impair the health of your laboratory animal
  • For those preparing their own diets, vitamin premixes are an efficient way to add vitamins to a diet
  • Vitamin mixes should be stored at 4 degrees celsius or lower upon receipt. Storage at –20 degrees celsius is recommended if the mix will be used beyond 1 month
  • Minimum order is 500 g for both stock and custom vitamin mixes
  • Our available vitamin mixes are commonly used in diets, and are available from stock
  • Vitamin mixes are shipped within a few days of order

Our Formula examples

  • CA.40060 Teklad vitamin mix
  • CA.40077 AIN-76A vitamin mix

Standard Natural Ingredient Diets

A more complete name would be Standard Natural Ingredient Diets. These diets are manufactured in large quantities (at least 2 tons) and stocked at one or more Envigo Teklad distribution centers. Standard natural ingredient diets are readily available and can generally be delivered within a few days after an order is placed. These diets primarily contain grains (corn, wheat), legumes (soybean meal) and to a lesser extent ingredients such as fish meal, and meat and bone meal. Standard natural ingredient diets include Global and Traditional diets and are available Irradiated and/or Certified.

Using standardized fixed formulas and ingredients purchased under the same stringent specifications in the United States and Europe, Envigo’s unique Teklad Global Diets Program provides nutritional consistency to national and multinational companies for their worldwide research, maximizing global study uniformity. Global Diets have the same product names in all countries. The Global Rodent diets have lower protein levels than most traditional diets and are formulated free of alfalfa with zero or modest amounts of soybean meal, thus minimizing the presence of natural phytoestrogens.

Envigo offers a variety of Traditional Teklad diets for the common laboratory animal species. These fixed formula diets are made from high quality ingredients. While traditional diets will supply the known nutrient needs of laboratory animals, we recommend that researchers consider the use of a diet from our Global Diet line. The traditional rodent diets were formulated decades ago based on understanding of rodent nutrition, ingredients, and diet manufacturing at the time. There was limited appreciation of the effects of non-nutrients, such as phytoestrogens, on experimental results. Alfalfa meal and soybean meal are the major sources of phytoestrogens in laboratory animal diets. These ingredients, particularly soybean meal, are found in most traditional rodent diets.

Fixed Formula diets are diets that are manufactured in accordance with a formula that remains unchanged from one production to the next. In conjunction with strict quality standards for raw materials, this approach ensures quality and consistency by minimizing nutrient variability and the variability of other phytochemicals in the diet which might affect a research study.

Certified diets are diets that have been tested for a standard panel of environmental contaminants that are known to be capable of interfering with a study. These diets help ensure that a study complies with the FDA’s Good Laboratory Practices regulations requiring periodic feed analysis. An Envigo certificate of analysis signed by a nutritionist is made available to the customer.

Our #1 goal is to provide quality and consistent products to our customers. This begins with ensuring that raw materials of only the highest consistency and quality are obtained. Raw materials are only obtained from approved suppliers who agree to meet our quality standards. Suppliers are audited on a regular basis and their products are tested for quality before being accepted into our facilities. Fixed formulas and established manufacturing procedures are in place for each product which ensure that the product is manufactured consistently with each production. In-process and final product testing is completed prior to distribution of the product to a customer. Envigo utilizes its own network of company owned and operated distribution centers throughout the US and Canada rather than use outside distributors.

There is no definitive point where one is able to predict when a specific diet will spoil or become deficient in one or more nutrients. The common guideline of a 6 month shelf life is based on longstanding practice in North America. In Europe and Asia, differences in local practices and regulatory oversight have led to Teklad standard natural ingredient diets being routinely used out to 9 months and sometimes 12 months post-manufacture. This practical experience, along with literature support and vitamin testing over time, gives us confidence that these diets continue to support animal health and study integrity out to at least 9 months post-manufacture. Please refer to your institution for guidance if you are unsure of local policies.

没有一个人能够预测当特定的饮食会破坏或缺乏一个或更多的营养。在常见的 6 个月的货架寿命是基于长期的实践中。在欧洲和亚洲 , 不同地方的做法和监管标准 , 导致 Teklad 饮食天然成分通常使用了 9 个月和 12 个月后有时制造。这种实践的经验 , 再加上文学和测试支持 , 让我们继续支持这些膳食研究动物的健康和完整性至少 9 个月后制造。请参考您的机构的指导 , 如果你不确定的地方政策。

Recommended storage conditions:

  • Cool and dry; at or below 70 degrees Fahrenheit, humidity below 50% ideal, but up to 65% is acceptable
  • Clean and free of pests
  • In original packaging or in a container that prevents continuous exposure to light and minimal exposure to air

建议贮藏条件 :

  • 冷却和干燥 ;在等于或低于 70 华氏度 , 湿度低于 50% , 但高达 65 % 是可接受的
  • 干净 , 没有害虫
  • 在原包装或容器 , 防止在连续的光暴露和最小暴露于空气中

Envigo offers irradiated diets, bedding, and enrichment items. Irradiation reduces the bioburden (number of organisms) contained by a product by exposing the product to gamma ionizing radiation from cobalt-60. Organisms exposed to gamma irradiation are damaged at the molecular level often with lethal effects. The net result is a decrease in the amount of viable microorganisms present in the product. Envigo irradiates all Teklad products at a minimum dose of 2.0 Mrad (20kGy) and a maximum of 5.0 Mrad (50 kGy).

Autoclaving destroys vitamins and amino acids that are supplemented in the diet. To compensate for this destruction, autoclavable diets contain an additional supplement of vitamins and supplemental amino acids. Autoclavable diets are packaged in perforated bags which allow steam from the autoclave to penetrate throughout the diet when the diet is autoclaved inside the bag.

Phytoestrogens are phytochemicals naturally produced by plants which interact with endogenous estrogens. They have some similarity in molecular structure compared to endogenous estrogens and bind to some extent with estrogen receptors. Phytoestrogens have been shown to affect mammalian physiology including cancer growth, atherosclerosis, calcium-phosphorus metabolism, and behavior. This is of concern to researchers because standard natural ingredient diets are often composed of ingredients which contain significant quantities of phytoestrogens. Soybean meal is an ingredient common to standard natural ingredient diets which contains a class of phytoestrogens called isoflavones. The two primary isoflavones are genistein and daidzein. Alfalfa meal is a second ingredient common to standard natural ingredient diets. It contains the phytoestrogen coumestrol.

Custom research diets

COLLAPSE ALL TABS

Custom research diets are made in small quantities and are generally not stocked. These diets are typically formulated for a specific type of research objective. These diets can consist of refined ingredients (purified diets), natural ingredients (grain and other ingredients found in standard diets), or utilize a standard diet as a base to which other ingredients are added. Any of these diet types can serve as the basis to add a customer supplied ingredient (test article, pharmaceutical, food extract, etc). We have approximately 20,000 diets in our database, so the formula you require may already have been created. We also utilize this database as a resource when formulating new diets. We will be pleased to provide you a complete formula sheet, containing the ingredients and inclusion rate, macronutrient values, key features, and planning and ordering information.

Purified diets use refined ingredients such as casein, sucrose, cornstarch, and cellulose. These human food grade ingredients have relatively simple chemical compositions (predominantly one nutrient classification) and this feature is important for manipulating individual nutrients for research purposes. Additionally, most refined ingredients contain very limited levels of non-nutrients that could have biological activity. This is in contrast to the natural ingredients (corn, wheat, soybean meal, etc.) used in standard diets, which have relatively complex chemical compositions as well as various phytochemicals that may or may not be physiologically relevant. Refined ingredients are obtained from reliable suppliers of human grade products, and we consistently obtain ingredients from the same vendors, year after year. Additionally, the major protein ingredients are assayed for a specific panel of nutrients to ensure minimal variation. Thus, purified diets will be repeatable and can easily be modified. Examples of common purified diets include AIN-76A (CA.170481), AIN-93G (TD.94045), and AIN-93M (TD.94048).

The American Society for Nutrition (ASN) (formerly American Institute of Nutrition, AIN) has promoted the use of nutritionally adequate purified diets for rodents, because many researchers may not be aware of potential nutritional variables. The AIN-76 formula was published in 1977, and became AIN-76A with minor revision (increased Vitamin K) in 1980. The diet has been used extensively, and there were several suggestions about improvements. This resulted in the publication of two formulas in 1993, AIN-93G (for growth, reproduction, and lactation) and AIN-93M (for maintenance). The article J. Nutr. 123: 1939-1951 (1993) discusses the rationale for the several revisions. Some of the changes include soybean oil rather than corn oil, the addition of other carbohydrate sources and lower sucrose, decreased phosphorus, cystine in place of methionine, inclusion of several trace mineral elements, and a few vitamin adjustments. The maintenance diet has less protein and fat.

Each formula is given a unique identification number and retains that identity among the thousands of formulas in our files. This assures the same formula will be used even years later. Upon production, a six or seven-digit “Rx” lot number is assigned that allows for traceability through all phases of diet production. These detailed production records are kept for every item produced. Quality-control samples are retained for nine months. Each lot of the major protein ingredients is analyzed for a number of nutrients to verify uniformity from lot to lot. Care is taken to retain reputable vendors for these refined ingredients.

Yes, we can help you in adding a test compound or ingredient to a diet. This is often a convenient approach to dosing research animals. When adding a compound to a diet, there are some important safety and stability considerations. Please see customer supplied ingredients for more specific information.

A phone call or an email exchange with one of our staff will augment the information that you gather from the web site or published literature, and you are more likely to receive a diet that best meets your particular needs. We are careful to maintain confidentiality, and will sign formal agreements if necessary. Please contact us at info@jinpanbio.com for consultation regarding your specific diet needs.

Advise us why the diet is needed, and for what animal species. Discuss the nutrients or ingredients of interest in as much detail as possible. Please avoid subjective descriptions such as “low, normal, and high” because these terms have different meanings to various researchers. Provide us with a copy of any existing formula to be duplicated or modified, and any journal article(s) upon which your research may be based. Let us know if the diet must be irradiated.

Our minimum order for custom research diets is 3 kg. This is particularly convenient when feeding small numbers of mice, especially for diet that contains your test compound. The minimum quantity for vitamin and mineral mixes is 500 g.

我们的饮食风俗研究最少是 3 公斤。这是特别方便的小数量喂养、饮食含有测试化合物。在最小量的维生素和矿物质混合料是 500 克。

Prices are dependent on formula details, ingredient composition, order quantity, and form (pellet or powder). If you know the product code, contact customer service at  info@jinpanbio.com. If you are unsure of the product code, have a new request, or require other technical information, contact a Nutritionist info@jinpanbio.com.

Standard packaging includes a small box (nine x nine x 11 inches) that will fit up to five kg, a medium box (ten x ten x 15 inches) that will fit up to ten kg, and a larger heavy-duty box (13 x 13 x 20 inches) with inset handles that holds up to 20 kg. Every container also includes a three-mil poly liner to keep your research diet as fresh as possible. Vacuum packaging and specific quantity packaging are also available at additional cost. Vacuum packaging will typically reduce the amount of diet fit into a box. Contact us at info@jinpanbio.com for more information.

Diets are custom made to fill each order. The typical lead-time between order and shipment is ten business days. The exceptions to this are TD.88137, TD.06414, and TD.01306 which for orders of 25 kg or less, are usually available within a week. If irradiation is required (add ten business days). We can often accommodate your rush production needs, for an additional fee. Contact us at info@jinpanbio.com for more details. Transit time depends on the type of delivery method used (regular ground, overnight, etc.). Weight and delivery method affect shipping costs, which are typically prepaid and added to the invoice.

There is no definitive point where one is able to predict when a specific diet will spoil or become deficient in one or more nutrients. Custom research diets are perishable and should be refrigerated at 4 degrees celsius (40 degrees fahrenheit) or lower (see Fullerton, et.al. J Nutr. 112:567-573, 1982). As a general guideline, diets can be stored this way for up to six months. Freezing a diet may slow reactive processes, but there is not sufficient information available to recommend feeding a diet past six months as a general guideline. Use of diets beyond the recommended use date will be subject to the protocols of your institution.

Custom research diets vary significantly in their formulation. There may be certain features of a diet that merit a shorter shelf-life. To learn more about storage and use recommendations, and to help you asess if your diet has features that may warrant a shorter shelf-life we have put together a guide. If you have further questions about your diet, contact us at info@jinpanbio.com.

Barrier facilities or certain animal models require sterilized diet. Most custom research diets do not withstand autoclaving; however, we can arrange for qualified diets to be irradiated. The irradiation dose range is two to five MRad, or 20-50 kGy. Nominal fees and extra time are involved. Please contact us at info@jinpanbio.com for details about irradiation costs and additional lead-time.

A nutritionist can assist you in determining if a formula is suitable for irradiation. Irradiation will lead to selective vitamin loss, and it is our practice to increase the inclusion rate of certain vitamin mixes to help ensure that the final diet contains sufficient vitamins. Irradiated diets are double-bagged. Vacuum packaging may be helpful in reducing irradiation-induced peroxide formation in high fat diets.

Some diet formulas are fairly common or generic, and probably are not considered confidential by those who use them, especially when authors provide a product number. Formulas might be difficult to trace without a product number, and then must be discussed with a nutritionist. We will review each formula for history and confidentiality.

Provide us with at the very least a description, preferably the complete formula, and we’ll give you an assessment of our ability to make that formula.

There are limitations for pelleting diets. The level and type of fat, the carbohydrate composition, and the interaction of fat and carbohydrate will impact our ability to pellet a diet. Consult a nutritionist at info@jinpanbio.com for more information about specific formulas.

“Vitamin-Free” Test Casein is an alcohol-extracted casein prepared from regular casein, and typically has 90-91% protein (%N x 6.38), 0.1% fat, and four-six % moisture. The alcohol extraction reduces fat, fat soluble vitamins, and some of the B vitamins. This protein source is most appropriately used in vitamin deficient diets, and when researchers want to minimize “background fat” in a diet. We have prepared this specialty ingredient for many years, and continue to supply it to many labs. We will develop special pricing on request for large quantities. Advance notice is recommended for orders of 1,000 Kg or more. If you need this ingredient, consider Envigo as your preferred source.

Yes. Some of the same high-quality ingredients used to produce custom research diets can also be supplied to those who prepare their own diets. See diet ingredients for more information.

When citing Teklad diets, include a description, and a product number — standard grain based diets are typically four numbers while custom diets usually start with “TD” followed by five or six numbers. Use the following examples as a guide:

“Rats were maintained on minimal phytoestrogen diet 2016 Teklad Global 16% Protein Rodent Diet, Envigo, Madison, Wisconsin USA, www.amrescoinc.cn”

“Obesity was induced by feeding Teklad high fat diet TD.06414 with 60% of kcal from fat, primarily lard, Envigo, Madison, Wisconsin USA, www.amrescoinc.cn”

“Mice were fed Teklad vitamin D deficient diet TD.89123, Envigo, Madison Wisconsin USA, www.amrescoinc.cn

Each diet has a unique product number that will allow others to quickly and easily obtain information about the diet used in your studies by contacting info@jinpanbio.com

No. According to the NIH OACU Guidelines for Use of Non-Pharmaceutical-Grade Chemicals/Compounds in Laboratory Animals (2008), the vehicle used to facilitate administration of a compound is as important of a consideration as the active compound in the preparation. Diet as a vehicle, either whole or as the sum of its parts, would not meet the standard for pharmaceutical grade as defined by this document.

You may have been asked this question by your IACUC due to a passage in the 8thedition of the Guide for the Care and Use of Laboratory Animals (2011) stating that pharmaceutical-grade chemicals and other substances should be used, when available, for all animal-related procedures (page 31). In general, deviations from “Must” or “Should” statements within the Guide require justification and approval by your institutional IACUC.

Alternative dosing techniques (gavage, injection) can introduce stress from handling and increase the risk for potential injury. Stress can affect animal well-being as well as scientific parameters through modifications in behavior and physiology. Dosing via diet is an established method for delivering test compounds to animals that is non-invasive, reducing stress and potential injury from handling. Therefore, use of non-pharmaceutical grade compounds as a delivery method is justified, as it is advantageous for both animal welfare and experimental design.
