摘要
从125头牛羊采乳样342份,同时用自制SMT-Ⅰ、SMT-Ⅱ、SMT-Ⅲ、BMT以及体细胞计数进行了隐性乳房炎检测。以体细胞计数结果为标准,阳性符合率为指标,对每种方法的效能进行了比较。结果显示:BMT与体细胞计数的乳区阳性符合率为97.67％、SMT-Ⅰ、SMT-Ⅱ、SMT-Ⅲ与体细胞计数的乳区阳性符合率分别为99.6％、96.51％、和96.51％。BMT检出时间为50秒,而SMT-Ⅰ只需5秒,SMT-Ⅱ和SMT-Ⅲ需10秒,可见三种SMT诊断液比BMT反应更强,反应时间更短,灵敏度更高,尤其是SMT-I,反应时间最短,与体细胞计数的乳区阳性符合率最高,是三种SMT中效果最好的。本文还阐述了SMTS的检测原理,同时对BMT、SMTS和体细胞计数法的优缺点进行了讲述。
342 milk samples were collected from 125 cows and milk goats.Thesubclinical mastitis was detected by SMT- Ⅰ 、 SMT- Ⅱ 、 SMT- Ⅲ 、 BMT andsomatic cell count(SCC).The results show between BMTand SCC, the quarterpositive accord fate is 97.67%,between SMT- Ⅰ 、 SMT- Ⅱ 、 SMT- Ⅲ and SCC,the quater positive accord rates are 99.6%, 96.51% and96.51%respectivcly.The response time for BMT is 50 second for SMT- Ⅰ only, 10 second for SMT- Ⅱ and SMT- Ⅲ respectively.The dctcctiv principle of SMTs was cxpounded,the dismerit and merit of BMT. SWTs,and SCC were discussed.
