摘　　要：对192头成年荷斯坦牛乳中体细胞数及乳房性状与泌乳性能的相关性进行研究,结果表明:乳中体细胞数较高,9月份达到最高水平;乳房性状评分偏低。体细胞数与月产奶量、月乳脂产量及月乳蛋白产量等性状有极显著负相关(p<0.01),与乳脂率和乳蛋白含量无显著相关关系(p>0.05);后乳房宽度与月产奶量、月乳脂产量及乳蛋白产量有极显著正相关(p<0.01)。The relationship among milking traits and udder traits,SCC in milk for 192 Chinese Holstein in south in 1999 were studied.The results show that the SCC was highest in September,the scores of udder traits were normal.The correlation between SCC and milk yield, milk fat yield,protein yield was significant,and SCC have no significant relationship with milk fat percent and protein percent.The correlation between the fore udder width and milk yield,milk fat yield,protein yield was positively significant.
