Jobs in dairy science include everything from working as a veterinarian to farm and ranch management. As a dairy scientist, you research the production of milk on a farm. Your responsibilities include working closely with an animal as a vet or dairy farm worker to understand any issues surrounding its lactation. Other duties involve studying milk yields, improving animal welfare, and keeping animals healthy on a farm or ranch. Some dairy scientists work for drug companies to develop medicines and supplements for dairy cows. You can also work in a federal, state, or local agricultural department, creating policy involving the dairy industry.
