Dietary supplementation with L-citrulline improves amino acid composition and broiler performance, and modulates gut microbiota

Poultry lacks carbamoyl phosphate synthetase, which is a key enzyme in the endogenous synthesis of arginine, thus poultry must obtain arginine from their diet.Citrulline (L-Cit), as a precursor of arginine, produces the same biological effects as arginine, and may even be more effective. In these experiments
