摘要: 对呼和浩特市郊区一牧场30头荷斯坦乳牛进行6个月跟踪采样,共得427个有效样本。根据体细胞数的高低将乳样分成五个不同的组,分别测定样本的氯、钾、钠、游离钙、总钙含量。结果表明:牛乳中氯、钠的含量与SCC呈显著的正相关(p<0.001);游离钙含量与SCC有一定的负相关(p<0.05);总钙、钾离子的含量与SCC的相关性不显著(p>0.05)。乳中体细胞数和乳中氯、钾、钠、游离钙、总钙含量与月份没有相关性(p>0.05)。氯与总钙有显著的正相关性(p<0.001);乳中氯离子与钠离子之间;总钙与游离钙之间有一定的正相关(p<0.05);钠离子与总钙之间有显著的正相关(p<0.01)。其余离子之间相关性均不显著(p>0.05)。

Abstract: 427 milk samples were collected from 30 Holstein dairy cows in the farm of Huhhot suburb during May to October in 2005.The milk samples were segregated and categorized into five different SCC(somatic cell counts)groups.The concentrations of chloride,potassium,sodium,total calcium,free calcium ion in milk and SCC were determined respectively.The results showed that significant positive correlation exists among concentrations of chloride,sodium and the SCC(p<0.001);the correlation between free calcium and SCC is negative(p<0.05);while total calcium and potassium are poorly correlatied(p>0.05).The correlation between the contents of SCC,chloride,potassium,sodium,total calcium,free calcium ion in milk and month is poor (p>0.05).The concentration between chloride and total calcium has significant positive correlation(p<0.001);The positive correlation exists between the chlorideion and sodiumion between the total calcium and free calcium and between the sodiumion and total calcium(p<0.05).The rest is of correlation(p>0.05).
