Research Diets, Inc. formulates and produces purified OpenSource Diets® for laboratory animals. Our Resource Center is staffed with PhD level scientists who consult on diet formulations with researchers worldwide. The open formulas allow scientists to report, repeat and revise their work. We have formulated over 20,000 original diets, and regularly incorporate test compounds at specific concentrations. We also manufacture the BioDAQ® Food and Water Intake Monitor. The BioDAQ electronic monitoring system records the moment-to-moment, bout-by-bout intake activity of rats and mice, in the context of the animals' behavior rather than fixed time intervals. BioDAQ Unplugged records undisturbed periodic intake measurements. BioDAQ NHP measures and records feeding bouts of socially housed, RFID implanted, non-human primates.
