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.
# Testing for macromolecules
Students determine the contents of soybeans.
# Reading labels
Students learn what a feed label contains and use that information to compare different dog foods.
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.
