CMT法与BTB法检测奶牛隐性乳房炎对比试验

Subclinical Mastitis Detection Experiments Comparing CMT Method and BTB Method

乳房炎是对奶牛养殖业危害最严重的疾病之一,特别是隐性乳房炎,由于没有明显的临床症状,不仅会导致奶牛乳产量和质量降低,而且还可能传染给其他奶牛,导致疾病的扩散。因此,对隐性乳房炎进行监测是奶牛场最重要的工作之一,由于患隐性乳房炎的奶牛没有明显的临床症状,只能对乳汁进行检测,通过有关生理、生化等指标的变化来判断和评价乳房炎的发生情况。试验通过加州乳房炎测试(CMT)法和乳汁PH检查(BTB)法对黑龙江省绿色草原牧场的502头处于泌乳期奶牛进行隐性乳房炎检测,统计分析各种因素与隐性乳房炎发病率的关系,并对这两种检验方法的结果进行比较分析。综合比较,CMT法检验比BTB法更好。

Mastitis was one of the most serious diseases that affect the dairy industry, especially subclinical mas- titis. There is no obvious clinical symptoms, not only will lead to lower milk production and quality of cows, but also may spread to other cows, leading to the spread of the disease. Therefore, the monitoring work of subclinical mastitis in dairy farm is the most important. The cows with subclinical mastitis have no obvious clinical symptoms, only a variety of methods are used to detect the milk and to determine and evaluate the incidence of mastitis through physiological, biochemical, and other indicators. Through the california mastitis test （CMT） method and the pH value of milk inspection （BTB）, 502 head cows in lactation were detected in Heiiongjiang Province green land. The relationship between various factors and the incidence of subclinical mastitis was analyzed statistically, and the results of the two methods were compared and analyzed. General comparison, CMT method was better than BTB method.
