不同管理条件下奶牛隐性乳房炎发生初探

Study on the Relationship Between Subclinic Mastitissand Different Raising Condition

乳汁中的体细胞增多,特别是白细胞增多是乳房炎的特点之一,因此,根据乳中体细胞数含量的多少来判断是否患有隐性乳房炎是一种可靠的检测手段。本试验对不同管理状况下的奶牛随机抽样以检测乳汁中的体细胞数,结果显示:来自管理状况较好的合肥某乳业公司样本中的体细胞数明显低于安徽农业大学校牧场样本的体细胞数,两样本相比较,前者隐性乳房炎的发病率(30%)低于后者的发病率(50%)。

Somatic cell increasing especial leucocyte increasing in milk is one of crucial characteristic with mastitiss. so the amount of somatic cell in milk is regarded as a credible means to check subclinic mastitiss. cows in this test raised in different condition were chosen randomly to count somatic cell in milk. The result indicated that cows chosed from a dairy company had lower ratio30% in subclinic mastitiss than those from Anhui Agricultural University's pasture50%.
