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]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指标进行测定。[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1986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。[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 was observed 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 breeding and improvement from draft type to meat type for more than 30 years,Jiaxian Red Cattle have achieved good growth performance and meat performance.
