Animal nutrition
Which macromolecules are found in animal feed?
Animal nutrition focuses on the dietary needs of animals—not just those in agriculture and food production, but also in zoos, aquariums, and wildlife management. Pets need good nutrition, too. In this lesson, students compare pet foods. See teacher background →

Teacher background
Macronutrients play a critical role in animal nutrition. Proteins help to build tissue and enzymes, carbohydrates provide fuel for the body, and lipids protect tissue and aid in neural development. Animal nutrition experts create feed for animals by blending together different macronutrients and minerals. Grains are a primary source for these macronutrients and soybeans are an important source of protein.
