Abstract

Abstract: In order to investigate the effect of supplementary feeding on meat yield and quality of yak, the weight of 8 cuts and quality parameters of 3 cuts including chuck tender, ribeye and striploin of the yaks assigned into 2 groups with or without supplementary feeding were determined.The results showed that the meat yield of superior cuts could be significantly (P< 0.05) increased by supplementary feeding such as ribeye and tenderloin with increasing range of 80% and 100%, respectively.The technological parameters of chuck tender, ribeye and striploin were influenced by supplementary feeding with decreased water holding capacity and significantly improved tenderness.The supplementary feeding had no significant effects on meat colour of yak (P >0.05).There were no significant effects of supplementary feeding on protein content of chuck tender, ribeye and striploin of yak (P >0.05).Supplementary feeding significantly increased fat content and decreased moisture of chuck tender (P< 0.05).The results indicated that supplementary feeding could raise production of superior cuts of yak and improve quality of yak beef.

Key words: Gaoyuan yak; supplementary feeding; meat production; meat quality
