Field peas(Pisum sativum L.) are a valuable and versatile nutrient source for a range of livestock species in several regions of the world. Interest in growing field peas as a feedstuff for livestock is increasing in the upper Midwest. Peas are a relatively new crop in Iowa where corn and soybean meal are the primary ingredients of swine diets. The growing season,seed characteristics, and other agronomic factors influence the nutrient content of peas. Hence, it is important to understand the nutrient levels of locally grown peas before incorporating them in swine diets.
