Functional dipeptides carnosine and anserine are abundant in muscle. We determined the effect of short-term dietary histidine (His) content on muscle carnosine and anserine contents and meat quality of broilers. Three groups of 28-day-old female broilers were fed diets with His contents of 67%, 100%, or 150% of requirement for 10 days before market (His contents 0.21%, 0.32%, and 0.48%, respectively). The carnosine and anserine contents of 0-h aged muscle significantly increased with dietary His content; in particular, the carnosine content was 162% higher in the His 0.48% group than in the His 0.32% group. The contents of both peptides also increased with dietary His content in 48-h aged muscle, but carnosine was not detected in 0- and 48-h aged muscle of the His 0.21% group. The drip loss, cooking loss, shear force, and pH of meat were not affected by the dietary His content. The 2-thiobarbituric acid-reactive substances contents of 24- and 48-h aged muscles were lower in the His 0.48% group than in the other groups, and the a* and b* values were lower in the His 0.21% group. These results suggest that short-term dietary His content affects imidazole dipeptide contents, antioxidative capacity, and color of broiler meat.
