摘　　要：[目的]探索奶山羊乳中体细胞数与乳成分含量的变化,分析其相关性。[方法]选择山东省内6家奶山羊场的120只奶山羊为试验对象,取其乳汁检测体细胞数、乳脂肪、乳蛋白、乳糖、总固形物含量和酸度,同时记录其产乳量。[结果]不同奶山羊场的羊乳体细胞数、乳脂肪、乳蛋白、乳糖、总固形物含量和酸度存在较大差异。体细胞数与乳蛋白含量具有显著性正相关(P<0.05),相关系数为0.9173;与酸度具有显著性正相关(P<0.05),相关系数为0.8627;与乳糖含量具有显著性负相关(P<0.05),相关系数为0.7263。[结论]羊乳体细胞数和乳脂肪、乳蛋白、总固形物含量和酸度等为正相关,与乳糖含量呈现负相关。[Objective]To explore the changes of somatic cell count and the content of components in milk of dairy goats,and to analyze the correlation.[Method]One hundred and twenty dairy goats from six dairy goat farms in Shandong Province were selected for observation,and their raw milk samples were taken to detect the somatic cell count,the contents of milk fat,milk protein,lactose,total solids and acidity,and the milk production were recorded.[Result]Somatic cell count,the contents ofmilk fat,milk protein,lactose,total solids and acidity varied considerably among different dairy goat farms.Correlation analysis showed that somatic cell count in goat milk was significantly positively correlated with milk protein content(P<0.05),with a correlation coefficient of 0.9173.Acidity was significantly positively correlated with milk fat content(P<0.05),with a correlation coefficient of 0.8627.Lactose content was significantly inversely correlated with milk protein(P<0.05),with a correlation coefficient of 0.7263.[Conclusion]Somatic cell count and the contents of milk fat,milk protein,total solids,total solids,and total solids of dairy goats in different dairy farms differed significantly.The contents of milk fat,milk protein,total solids and acidity were positively correlated and negatively correlated with lactosecontent.
