摘要
旨在研究夷陵牛的生长性能、屠宰性能和肉质性状。对56头成年夷陵牛体重和体尺指标进行测定,对91头夷陵牛初生及6、12、18月龄阶段的体重进行测定,并选取育肥后的夷陵牛20头(公母各半)测定其屠宰性能和肉质性状。结果:生长性能方面,夷陵公牛的体重及体尺指标均显著优于母牛个体(P<0.05);屠宰性能方面,夷陵公牛屠宰率为55.56%,净肉率为46.36%,胴体产肉率为83.44%,肉骨比为(5.04±0.85),眼肌面积为68.10 cm^(2),夷陵母牛屠宰率为49.32%,净肉率为40.23%,胴体产肉率为81.57%,肉骨比为(4.43±0.73),眼肌面积为56.34 cm^(2),差异均显著(P<0.05);肉质性状方面,夷陵公母牛在大理石花纹、肉色、嫩度等指标方面基本保持一致,鲜肉中氨基酸比例以及多种不饱和脂肪酸比例适当。综上,夷陵牛肉品质较好,夷陵公牛具有良好的产肉性能,可生产高档牛肉,夷陵母牛需通过本品种选育结合导入杂交进一步提高肉用性能。
The aim of this study is to investigate the growth performance,slaughter performance,and meat quality traits of Yiling cattle.The body weight and body size indicators of 56 adult Yiling cattle were measured,and the body weight of 91 Yiling cattle at the stages of birth,6,12,and 18 months of age was determined.Twenty fattened Yiling cattle(half male and half female)were selected to measure their slaughter performance and meat quality traits.The results showed that in terms of growth performance,the body weight and body size indica⁃tors of Yiling male cattle were significantly better than those of female cattle(P<0.05).In terms of slaughter performance,the slaughter rate of Yiling male cattle was 55.56%,the net meat rate was 46.36%,the carcass meat yield was 83.44%,the meat-to-bone ratio was(5.04±0.85),and the eye muscle area was 68.10 cm^(2).For Yiling female cattle,the slaughter rate was 49.32%,the net meat rate was 40.23%,the carcass meat yield was 81.57%,the meat-to-bone ratio was(4.43±0.73),and the eye muscle area was 56.34 cm^(2),with significant differences(P<0.05).In terms of meat quality traits,Yiling male and female cattle basically maintained consistency in indicators such as marbling,meat color,and tenderness,and the proportion of amino acids and various unsaturated fatty acids in fresh meat was appropriate.The research results indicate that Yiling beef has good quality,Yiling male cattle have good meat production performance and can produce high-grade beef,and Yiling female cattle need to be further improved in meat performance through intraspecific breeding combined with crossbreeding.
