[Abstract] Maximizing the production performance of each pig has always been a common goal pursued by producers and nutritionists. Therefore, general diet formulation gives little or no consideration to nutrient excretion, resulting in excessive nutrients (mainly nitrogen and phosphorus) being excreted with feces and urine. In recent years, public concern for the environment has grown increasingly strong. Through nutritional technology, improving the feed conversion efficiency of pigs and reducing waste (feces and urine) has become a hot topic in current swine science and nutrition research.

[Abstract] Maximizing the production performance of each pig has always been a common goal pursued by producers and nutritionists. Therefore, general diet formulation gives little or no consideration to nutrient excretion, resulting in excessive nutrients (mainly nitrogen and phosphorus) being excreted with feces and urine.

By supplementing synthetic amino acids and reducing dietary protein, nitrogen excretion can be significantly reduced. Adding phytase to the diet can improve phosphorus utilization and reduce the amount of phosphorus added to the diet, thereby lowering phosphorus excretion. In addition, antibiotics, probiotics, single-cell protein and yeast, organic chromium, etc. also play a certain role in reducing nutrient waste in pigs.
