摘　　要：体细胞数超过奶牛正常生理值时,产奶量和体细胞之间呈负相关关系,体细胞越高负相关越强。当体细胞在20.36万/ml时,二者呈不显著负相关;当体细胞达到49.28万/ml时,二者呈强负相关;当体细胞达到68.32万/ml时,二者呈极强负相关。当体细胞在12.42万/ml时(正常奶牛的生理值),二者接近零相关。While somatic cells is more than standard of cows normal physiology, between milk output and somatic cells there is a negative correlation relationship,the higher somatic cells is,the more negative correlation. When the cells was at the 203,600 / ml, the two were not significant negative correlation; When the cells reached 492,800 / ml, both a strong negative correlation; When the 200 / ml,both a fortissimo negative correlation. When the cells in the 124,200 / ml values of cows）, both close to zero.
