What LabDiet does

LabDiet is a US-based manufacturer of precision laboratory animal diets serving the global biomedical research community for over 80 years, operating as a brand under PMI Nutrition International LLC, a subsidiary of the Land O' Lakes cooperative. The company formulates and produces specialized feed products for eleven-plus species including rodents, primates, canines, felines, ferrets, rabbits, guinea pigs, swine, poultry, ruminants, and amphibians, with core product lines spanning standard pelleted diets, irradiated diets (PicoLab, IsoPro, Pico-Vac), autoclavable diets fortified for steam sterilization, GLP-compliant Certified Diets with documented contaminant profiles, and Verified Diets for specialized research parameters such as low-isoflavone studies.

The company's underlying technology centers on its managed formulation system branded as Constant Nutrition, which adjusts ingredient ratios across production batches to compensate for natural compositional variation and deliver consistent nutrient profiles — a critical feature for reproducible long-term studies. Manufacturing occurs at a single FSSC 22000 and FSC34 certified facility in Richmond, Indiana, which was the first ISO 9002 certified specialty feed facility in the USA. Product differentiation is driven by irradiation treatment for microbial control, vitamin-fortified autoclavable formulations, and certified contaminant analysis for GLP toxicology compliance.

LabDiet operates an indirect go-to-market model through a global network of certified distributors across 15+ countries, with quote-based pricing on catalog products and additional revenue from custom formulations under the TestDiet sub-brand, the $50 PMI Laboratory Animal Care Course, and technical services including an online Analysis Retrieval System and product stability research. Customers span pharmaceutical laboratories, academic research institutions, and government research programs.
