Learn About How Our Company Develops Custom Diets

About Our Research Methods

If you are a research scientist, our company will be a great resource to help you provide custom formulated diets to your laboratory animals for your research. This site will provide a wealth of information to help you feel confident that you are providing the best food for your animals.

Dyets provides custom formulated diets for laboratory animals including rat, mouse, guinea pig, hamster, gerbil, cat, dog, ferret, rabbit, pig, monkey, and woodchuck, et.al. We welcome the chance to aid in developing purified diets for any other species or any new scientific pursuit.

Generally, we employ the American Society of Nutritional Science (ASNS) or National Research Council (NRC) recommended purified diets. Since we custom manufacture each diet, it is a simple matter to vary any or all of the constituents to meet individual researcher specifications.  This allows us to prepare diets with sufficient, deficient or excessive levels of each of the vitamins or minerals. Our diets will also provide quantitative and/or qualitative variation in the macronutrients, protein, carbohydrate, fat, and fiber. We also have broad experience with the formulation and production of L-Amino Acid based diets and our consultants will be happy to discuss your needs with you.

History of Our Company

A Note from the President of Dyets, Inc.

Dyets, Inc. was founded on July 1, 1979 by Howard L. Yowell  and Donald H. Yowell. During the past twenty years, Dyets’ hallmark ability to design, prepare, and ship custom diet formulations in a timely manner while maintaining an aggressive pricing policy was well received by investigators.

We remain very grateful to the many researchers who have chosen Dyets during the last 20 years. We have been privileged to work with Cornell University, University of Nebraska Medical Center, Wistar Institute in Philadelphia, University of Pittsburgh, and the University of Toronto.

Our company has come a long way since being a two-man operation. Since starting up, our view of reinvesting in both equipment and personnel is partially responsible for our very low employee turnover rate. At present time, Dyets six department leaders have worked at Dyets an average of 17 years. We believe speaking with an experienced Dyets employee smooths the bumps in the road and is the right way to help customers.
