Effect of precursor amino acids for carnosine synthesis on breast fiber microstructures and myofiber differentiation-related gene expression in slow-growing chicken

HIGHLIGHTS

• What: The authors aimed to investigate the effect of supplemen­ tation of the carnosine synthesis precursors, 1% β-alanine and 0.5% L-histidine, which have been shown to significantly increase the carnosine content in chicken breast meat without affecting lipid oxidation, on the characteristics and micro­ structure of muscle fibers in slow-growing chickens. The re­ sults of this study demonstrate the effects of supplementation with carnosine synthesis precursors on breast meat micro­ structure. In the present study, the IMF content varied among individuals and showed no sig­ nificant difference in relation to β-alanine and/or L . . .
