| 摘 要： | 为研究补饲对放养牦牛产肉能力及肉品质的影响,试验选取12头在海北州天然放养的牦牛,随机分为2组,即无补饲处理组(对照组)和补饲处理组(补饲组),屠宰后测定2组牦牛8个分割部位的肉重量以及辣椒条、眼肉、外脊3个部位的肉品质指标.结果发现,补饲处理显著增加了牦牛优质部位里脊和眼肉的产肉量(P< 0.05),增产幅度分别达到了80%和100%.辣椒条、眼肉和外脊的加工性能会受到补饲处理的影响,持水能力有所下降,而嫩度却显著改善(P< 0.05).肉色不会受到补饲处理的显著影响(P >0.05).补饲处理不会显著影响辣椒条、眼肉、外脊的蛋白质含量(P >0.05),但却可显著提高辣椒条的脂肪含量(P< 0.05),并显著降低其水分含量(P< 0.05).结果表明,补饲可增加牦牛优质部位肉产量,并改善牦牛肉嫩度.

| 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. |
