夷陵牛生长性能、屠宰性能及肉质性状分析
Analysis of growth performance,slaughter performance and meat quality traits of Yiling cattle
摘要
Abstract
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 cm2.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 cm2,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.关键词
