Harlan Teklad动物饲料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. Inotiv 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.

Harlan Teklad动物饲料Mineral Adjusted Diets

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

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.

Harlan Teklad动物饲料Rodent Diets

As a researcher, you want to have as much control as possible over what goes into your study animals. At Inotiv, we understand that. That is why we developed Teklad Global Rodent Diets® .

Teklad Global Rodent Diets® are a special integrated range of vegetarian laboratory rodent diets developed to be nutritionally complete for various life stages from breeding through long-term maintenance. Global rodent laboratory diets contain levels of protein, energy, vitamins and minerals that are more appropriate to the needs of modern biomedical research studies.

Furthermore, in global rodent diets particular attention has been placed on avoiding, as far as practical, ingredients that are reported to have adverse confounding effects on experimental results. This has resulted in a range of Teklad rodent laboratory diets that contain:

  • No fish meal
  • No meat meals or meat by-products
  • No alfalfa meal
  • No soybean meal or reduced levels
  • No animal fat

By excluding animal by-products, the presence of nitrosamines (a potential carcinogen) is avoided. Exclusion of alfalfa meal reduces chlorophyll, improving optical imaging clarity. Reduction or removal of soybean meal, together with elimination of alfalfa meal, minimizes levels of naturally-occurring phytoestrogens. Phytoestrogens interact with endogenous estrogens and potentially can affect studies in many research areas. Read more about this in these pieces:

Traditional rodent diets were formulated decades ago based on understanding of rodent nutrition, ingredients, and diet manufacturing at the time. While traditional diets will supply the known nutrient needs of your laboratory animals, we recommend you consider the use of a diet from our newer global diet line for your modern research needs.

Teklad Global Rodent Diets® are modern formulas designed to reduce research variables. Specifically, these diets contain more appropriate nutrient levels, and limit or exclude ingredients that are reported to have effects on a wide variety of research endpoints.

  • Lower, more appropriate protein levels can improve survival and reduce morbidity
  • Vegetarian with no nitrosamines (a potential carcinogen)
  • Formulated to exclude alfalfa meal, greatly improving fluorescent imaging clarity
  • Formulated to exclude or lower soybean meal, thus minimizing the presence of isoflavones, the primary type of phytoestrogen found in lab animal diets
  • Extruded rodent diets dramatically reduce clumping and hardness after autoclaving (2018SX , 2019S , 2020SX ), and in general result in less diet waste and cleaner cages

Teklad rodent diets are natural-ingredient diets specifically formulated to provide the proper balance of all known nutrients considered essential for the growth, maintenance, and reproduction of rats, mice, gerbils and hamsters. These diets conform to the nutrient requirements for rodents established by the National Research Council (1995).

Teklad rodent diets provide uniform nutrition. They are fixed-formula diets designed to minimize the nutrient variances which otherwise could occur if the ingredient composition of a diet were altered from one batch to the next.

Protein is supplied primarily by plant sources. Supplemental amino acids are added to provide the proper amount and balance of essential amino acids. All rodent diets are fortified with vitamins and minerals to help support the regulation of body fluids and the proper functioning of body systems to ensure the adequate growth, maintenance, and reproduction of research rodents. Autoclavable diets are supplemented with additional vitamins to compensate for losses that occur during autoclaving. Since our diets are nutritionally complete and balanced, it is not necessary to add dietary supplements.

Standard natural ingredient rodent diets are complete diets for rats, mice, gerbils and hamsters, that should be allowed ad libitum access to the diet. Fresh water should be available at all times.

Harlan Teklad动物饲料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.
