摘要
为了研究红安格斯×中国草原红牛一代(安草F_(1))育肥效果,随机选择体重相近的18月龄草原红牛(对照组)和安草F_(1)(试验组),在相同饲养条件下育肥至36月龄屠宰,分别测评24、30、36月龄的育肥性能和36月龄时的屠宰指标及牛肉品质。结果显示:试验组24、30、36月龄体重、胸围、屠宰率、净肉率和眼肌面积均显著高于对照组;剪切力显著低于对照组。综上,利用红安格斯牛杂交中国草原红牛,有利于提升生产性能、改善牛肉嫩度。
In order to study the fattening performance of the first filial generation of Red Angus×Chinese Red Steppe cattle(AHF_(1)),18-month-old Chinese red Steppe(Control group)and AHF_(1)(Treatment group)with similar body weight were selected randomly,and fattened to 36 months old in the same feeding situation.The fattening performance in 24,30,36 months old were measured,and the slaughter indexes and the meat quality indexes in 36 months old were evaluated.The results showed that body weight,chest circumference,dressing percentage,neat percentage and eye muscle area of treatment group were significantly higher than those of the control group in 24,30,36 months old,and the shear force value was obviously lower than control group.In conclusion,crossing Chinese red Steppe cattle with Red Angus could improve the production performance and beef tenderness.
