摘  要：
【目的】研究不同营养调控剂对肉牛生产性能、胴体品质和肉品质的的影响,为开发营养调控剂用于改善牛肉品质提供科学依据。【方法】试验选用18只荷斯坦公牛,依据体重和类型随机分为3组,试验组分别在精料中添加调控剂Ⅰ(100 g/d)和调控剂Ⅱ(108 g/d),对照组饲喂基础日粮。【结果】对照组、试验Ⅰ组、试验Ⅱ组,平均日增重分别为1.633 0、2.042 0和1.833 0 kg,与对照组相比,试验I组比对照组提高25.04%,差异显著(P<0.05);试验Ⅰ组和试验Ⅱ组的粗蛋白含量显著高于对照组(P<0.05),试验Ⅰ组的甘氨酸和精氨酸含量与对照组相比差异显著(P<0.05);试验Ⅱ组的赖氨酸、亮氨酸含量明显高于对照组(P<0.05),异亮氨酸含量差异极显著(P<0.01)。试验Ⅱ组对牛肉的背最长肌(IMP)和臀中肌(IMP)含量都极显著高于对照组(P<0.01),并且效果显著高于试验Ⅰ组(P<0.05)。【结论】两种营养调控剂都可以提高肉牛增重性能,改善牛肉品质。

摘  要：
【Objective】The main purpose of this article is study the effects of different nutrition additives on gain performance,carcass quality and meat quality of beef to provide scientific basis for research and development of nutrition additives.【Method】The selected 18 Holstein bull were divided radomly into 3 groups according to their weight and type.The experimental group fed chiefly on basal diet.【Result】The result indicated that there was significant difference of Average daily gain(ADG) among these groups,ADG of experimentⅠ was 2.042 0 kg,higher than that of the control group(P<0.05).ExperimentⅠand ExperimentⅡcould significantly increase the CP of meat(P<0.05).His,Lys,Leu,Gly contents are higher than that of the control group(P<0.05).and the inosinic acid content in every tiral group was higher than that of the control and adding nutrition addtivesⅡgroup was the best.【Conclusion】The two nutrition additives can improve the gain performance and the meat quality of beef.
