摘　　要：通过对育成荷斯坦奶公牛与西门塔尔牛、新疆褐牛及新疆土种牛肉品质部分指标的比较分析研究,旨在探讨荷斯坦奶公牛的肉品质。选择在相同营养模式下18月龄左右4个品种牛各3头进行屠宰,取右半边胴体的背最长肌作为肉品质试验样品,分别对牛肉的肉品质、常规营养成分及氨基酸含量进行测定和分析。结果表明,荷斯坦奶公牛肉色、失水率、系水力、熟肉率、大理石花纹等指标均优于新疆褐牛、新疆土种牛,次于西门塔尔牛;荷斯坦奶公牛嫩度优于新疆土种牛;粗蛋白质、粗灰分含量分别为20.14%、1.11%,且各品种间差异均不显著(P>0.05),干物质含量为26.30%,显著高于新疆褐牛和新疆土种牛(P<0.05),低于西门塔尔牛(P>0.05),粗脂肪含量为10.04%,显著高于其他品种牛(P<0.05);荷斯坦奶公牛含有人体需要的各种氨基酸,其中蛋氨酸、谷氨酸、甘氨酸、组氨酸、牛磺酸等含量丰富,氨基酸组成比例良好。By the comparative study on the beef quality of growing Holstein dairy bull,Simmental cattle,Xinjiang Brown calf and Xinjiang local cattle,the assay was aimed to explore the internal beef quality of the dairy bull.Four different breeds of 18 month age cattle were slaughter in the same nutrition model.Carcass were taken back up the right muscle as meat sample.Edible quality,normal composition of nutrition and amino acids were detected and analysed.The results showed that marbling,beef color,water losing rate,water retention capacity and cooking percentage of Holstein dairy bull were better than Xinjiang Brown calf and Xinjiang local cattle,but weaker than Simmental cattle.The tenderness of Holstein dairy bull was better than Xinjiang local cattle.The contents of crude protein and crude ash were 20.14% and 1.11%,there were no significant differences during each breeds（P＆gt;0.05）.The content of dry matter was 26.30%,it was significantly higher than Xinjiang Brown calf and Xinjiang local cattle（P＆lt;0.05）,lower than Simmental cattle（P＆gt;0.05）.The content of crude fat was 10.04%,which was significantly higher than other breeds（P＆lt;0.05）.Moreover,Holstein dairy bull contained every amino acids which were needed by human body.Among them,the contents of methionine,glutamate,glycine,histidine and taurine were rich,and the proportion of amino acid was also well.
