The objective of this study was to test the effects of dietary arginine on testosterone levels and semen quality in breeder roosters. Twenty male roosters were given four levels of dietary arginine for 8 weeks and then parameters were tested. Arginine is a semi-essential amino acid that is involved in helping to increase blood flow and keep blood vessels relaxed. Peanuts have one of the highest arginine levels in foods.
Results showed that when arginine was included in the diet, roosters experienced higher testosterone levels, better sperm motility, and better semen quality than roosters who were not given arginine.
