Laboratory Rodent Diet

The pellets fed to the rats in this course are made by PMI Feeds Inc., product code 5001. For students who are interested, I have taken the most relevant information from the PMI Feeds' "Laboratory Rodent Diet" sheet.

Description

Laboratory Rodent Diet is a constant-formula rodent diet recommended for rats, mice and hamsters. The constant formula feature is designed to minimize nutritional variables in long-term studies. It is formulated for life-cycle nutrition; however, it is not designed for maximizing production in breeding colonies.

This product has been the standard of bio-medical research for approximately fifty years.

Features and Benefits
Constant formula helps minimize nutritional variables.
Formulated for multiple species for single product inventory.
The rodent diet standard for biomedical research.

Product Form
Oval pellet, 3/8" x 5/8" x 1" length
