NE (Nutrient Requirements of Dairy Cattle)

NE, or Net Energy, refers to the amount of energy from feed that a dairy cow can use for essential functions like maintaining body weight, supporting growth, producing milk, and reproducing. It accounts for energy lost through digestion, activity, and heat. Understanding NE helps farmers select proper feeds to ensure cows stay healthy, efficient, and productive. The Nutrient Requirements of Dairy Cattle guidelines provide detailed recommendations on how much NE is needed based on factors like the cow's size, age, production level, and stage of lactation, helping optimize dairy farm management.
