中文摘要:
      [目的]通过屠宰测定分析,了解无角夏南牛的屠宰性能和肉质品质,为下一步无角夏南牛的选育提供资料。[方法]通过对20头24月龄无角夏南牛育肥公牛进行屠宰测定和肉质分析。[结果]20头无角夏南牛的屠宰率、净肉率、眼肌面积、肉骨比、高档优质肉块比率、高档肉块率分别为:62.62%、52.8%、111.17 cm2、5.82:1、49.69%和28.36%;肩肉、大黄瓜条、外脊3个部位的蛋白质含量分别为:23.602%±0.192%、20.852%±1.212%、21.522%±1.282%;脂肪含量分别为4.262%±1.612%、3.122%±1.052%、2.802%±2.492%;肌肉剪切力分别为:4.60kg±1.92kg、3.59kg±1.58kg、4.49kg±1.44kg。[结论]无角夏南牛的品种培育、改良效果显著,生产高档部位肉块的能力强、肉质好。
英文摘要:
      [Objective]Through slaughtering analysis, the slaughter performance and meat quality of hornless Xianan cattle can be understood, which can provide information for the next selection of hornless Xianan cattle. [Method]Slaughter determination and meat quality analysis were performed on 20 24-month-old hornless Xianan fattening bulls. [Results]The slaughter rate, net meat rate, eye muscle area, meat-to-bone ratio, high-grade and high-quality meat chunk ratio, and high-grade meat chunk ratio of 20 hornless Xianan cattle were: 62.62%, 52.8%, 111.17 cm2, 5.82:1, 49.69 % and 28.36%; the protein content of shoulder meat, large cucumber strip and outer ridge were: 23.60%,±0.19%,, 20.85%,±1.21%,, 21.52%,±1.28%,; fat content were 4.26%,±1.61, 3.12%,, respectively 3.122%±1.05%, 2.80%±2.49%; muscle shear force were: 4.60kg±1.92kg, 3.59kg±1.58kg, 4.49kg±1.44kg, respectively. [conclusion ]The breeding and improvement effect of hornless Xianan cattle is remarkable, the ability to produce high-grade meat pieces is strong, and the meat quality is good.
