Simultaneous improvement of breast muscle yield and meat quality in Langshan chickens.

ABSTRACT: Compared to white-featured broilers, the native Chinese Langshan chickens possess superior meat quality but have a lower growth rate and breast muscle yield. Increasing the breast muscle yield of these breeds while maintaining their high meat quality would greatly enhance their commercial value. Although elevated muscle growth often impairs meat quality, this relationship remains unclear in Langshan chickens. In the present study, 15-week-old Langshan chickens were divided into high (HPB, 14.15 %) and low (LPB, 9.85 %) percentages of breast muscle yield groups after slaughter. Differences in meat quality, myogenic capacity, protein deposition capacity, and metabolic profiles were investigated. Interestingly, the results demonstrated that, compared to the LPB group, the HPB group exhibited
