摘  要：
为研究经全哺乳饲养后,2.5岁及3.5岁麦洼公犊牦牛的生长发育及肉质特性。对2.5及3.5岁麦洼公犊牦牛进行屠宰试验研究。结果表明,2.5岁和3.5岁犊牦牛的宰前重、体高和体斜长存在极显著差异,管围具有显著差异,而胸围无显著差异。头、蹄、皮重均具有极显著差异,而生殖器睾丸重无显著差异。心脏、肝脏和肾脏重具有极显著差异,肺脏重具有显著差异,而脾脏无显著差异。2.5岁和3.5岁犊牦牛的胴体重、净骨重、净肉重、净肉率、胴体产肉率和骨肉比均具有极显著差异,眼肌面积具有显著差异,而屠宰率无显著差异。全哺乳方式对2.5岁及3.5岁犊牦牛,生长发育补充效果明显,均有较高的宰前重,且产肉性能良好。

摘  要：
A slaughter experiment was carried to investigate the growth and meat characteristic of Maiwa Yak at the age of2.5 and 3.5 under full-lactation situation. The results showed that, the weight before slaughter, the height and length of body,the weight of head, hoof, skin, heart, liver, kidney, carcass, bone and meat, as well as the pure meat percentage,meat-production percentage and meat-bone radio of carcass had highly significant differences between 2.5 and 3.5 years old yak(P <0.01). The cannon circumference, lung weight, eye muscle area showed significant difference(P <0.05). The heart girth,weight of testis and spleen, dressing percentage had no significant difference(P>0.05). It was indicated that full-lactation method could promote the growth and showed a higher weight before slaughter of Maiwa Yak at the age of 2.5 and 3.5.
