中文摘要:

      [目的] 通过研究郏县红牛的生长性能和肉用性能,系统评价其肉用潜力和优势。[方法] 试验选取4头郏县红牛经持续育肥后屠宰,对其体尺、屠宰性能、胴体指数和产肉性能进行测定。[结果] 经育肥后成年郏县红牛的体重、体高、体斜长、胸围、管围相较于986年分别增长45.64%、9.12%、20.11%、29.57%、18.33%,相较于2006年分别增长15.43%、0.65%、0.38%、11.84%、5.19%,体重和体尺明显增长。胴体重为322.15 kg、净肉重为288.27 kg、净肉率为53.87%、屠宰率为60.31%、肉骨比为7.20,优质牛肉产率为25.63%,其中胴体重、净肉率和肉骨比相对2007年分别增长10.17%、5.63%和22.03%,值得关注的是高档肉产率已达到15%,经济效益明显。[结论] 经过近30多年由役用向肉用方向的品种改良和选育,郏县红牛已具有了良好的生长性能和产肉性能。

英文摘要:

      [Objective] By studying on the growth performance and meat performance of Jiaxian Red Cattle, this research aimed to systematically evaluate its meat potential and advantages. [Methods] Four Jiaxian Red Cattle were selected and slaughtered after continuous fattening. Body size, slaughter performance, carcass index and meat production performance were measured. [Results] After fattening, body weight, body height, body length, heart girth and circumference of cannon of adult Jiaxian Red Cattle increased by 45.64%, 9.12%, 20.11%, 29.57% and 18.33% compared with 1986, and increased by 15.43%, 0.65%, 0.38%, 11.84% and 5.19% compared with 2006, respectively. It can be seen that body weight and body size increased significantly. In addition, the carcass weight was 322.15 kg, the net meat weight was 288.27 kg, the net meat percentage was 53.87%, the dressing percentage was 60.31%, the ratio of meat to bone was 7.20, and high-quality beef ratio was 25.63%. The carcass weight, the net meat percentage and the ratio of meat to bone were 10.17%, 5.63% and 22.03% higher than 2007, respectively. It is worth noting that high-quality beef ratio has reached 15%, so Jiaxian Red Cattle could gain good economic benefits. [Conclusion] After more than 30 years of breeding and improvement from draft type to meat type, Jiaxian Red Cattle have achieved good growth performance and meat performance.
