为探讨原料乳中乳脂率、乳蛋白率的影响因素及其之间的相关关系,本文收集新疆地区呼图壁种牛场牧一场和牧三场、天山畜牧生物股份有限公司牛场、沙湾金牛场、西部牧业共5个牧场4 727头次荷斯坦奶牛的生产性能记录,采用SAS(8.1)软件分析不同牧场、年度、季节、胎次对乳脂率和乳蛋白率的影响,并运用SPSS16.0软件进行相关性分析。结果表明:牧场、年度、季节、胎次均对乳脂率和乳蛋白率有极显著影响(P<0.01)。相关性分析结果表明,乳脂率与乳蛋白率呈极显著正相关,相关系数为0.11。通过分析牧场、年度、季节、胎次对乳脂率、乳蛋白率的影响及相关关系,加深影响乳成分因素的认识,提示在生产中要做好饲养管理工作,并根据季节变化、奶牛胎次的增加,结合奶牛营养需求,采取具体措施调控影响乳成分的因素,从而提高原料乳质量。
Abstract：This study seek to identify the impact factors of milk fat percentage and milk protein percentage in raw milk by recording the productivity of 4727 Holstein cows from 5 different pastures. The milk were collected from different pastures and the percentage of fat and protein in the milk were statistically analyzed(SAS8.1 and SPSS16.0). Results showed that the percentage of milk fat and milk protein were significantly different(P < 0.01) in pastures, years, seasons and generations indicating these could be the potential impact factors. There was positive correlation between the percentage of milk fat and milk protein with correlation index 0.11. These results suggest that the breeding techniques should be improved and the cows should be provided with enough nutrition in order to increase the quality of raw milk.
