Library Research Guide
The use or demand for specific pet food ingredients is difficult to determine. Manufacturers purchase ingredients through a variety of channels and do not disclose their formulations.
The library does not have a database that gives information about the ingredients in commercial pet food.
Available sources of information and insights about pet food ingredients include research from industry associations and the USDA.
The USDA provides data on crops that may be used as ingredients in pet food. USDA sources do not analyze use of grains or other ingredients in pet food products.
