Deep dives

The Impact of Ingredient Variability on Poultry Nutrition

Ingredient variability significantly affects poultry nutrition, particularly regarding energy sources like corn and soybean meal. Variability arises from different crop years and the moisture and fat content in feedstuffs, which can heavily influence the digestible energy available to birds. For example, the Annual Metabolizable Energy (AME) of corn samples can vary from 3,700 to 3,000 kcals per kilogram, impacting overall feed conversion rates. Understanding this variability helps nutritionists make informed decisions about feed formulation to optimize bird performance and maintain economic efficiency.
