Abstract

Early weaned piglets grow fast and have strong protein deposition ability, so they have high protein requirements. Dietary protein level has a profound effect on the growth performance, intestinal health, nutrient digestion, absorption and metabolism, and body protein deposition of weaned piglets, so it is a key factor for weaned piglets to develop their growth potential. Meanwhile, the protein requirement of weaned piglets is affected by their basic intestinal health, dietary amino acid balance and energy intake. This review summarizes the effect of dietary protein level on the production performance, the protein requirement standard and the factors affecting the protein requirement of weaned piglets. We tend to provide a theoretical basis for the study of protein nutritional requirement of weaned piglets under the condition of feed antibiotics prohibition and limited addition of copper and zinc.
