中文摘要 | 民國81年8月至82年6月間,以加州乳房炎測試法(California mastitis test; CMT) 檢測本省中部地區 17 個牧場 992 頭泌乳牛之 3, 968 個分房乳, 結果 17.4%(691/3968) 有 CMT2 級以上的潛在性乳房炎 (subclinical mastitis), 而盲乳 (blind quarter) 有 4.1%(163/3968) , 總計本省中部地區乳牛異常分房數高達 21.5%(854/3968)。細菌分離鑑定結果,得知乳房炎病原菌的出現率分別為:Streptococcus spp 49.0%(300/612), Staphylococcus spp 33.6%(206/612), Gram-negative bacilli 11.4%(70/612), Yeast 0.2%(1/612) 及 others 5.8%(35/612)。 |
英文摘要 | A survey of the prevalence of bovine subclinical mastitis in 17 dairy farms located at the middle area of Taiwan was conducted by employing the California mastitis test (CMT) from Aug. 1992 till June 1993. Totally, 992 milking cows including 3968 udders, were examined in this study. The results showed that 17.4%(691/3,968) of the investigated bovine udders had a CMT value reaching 2 and 3 degrees, which is the indication of bovine subclinical mastitis, whereas 4.1%(163/3,968) of the bovine udders had already become the "blind quarter". Accordingly, the prevalence rate of the abnormal bovine udders at the middle area of Taiwan was calculated as high as 21.5%(854/3,968). The incidence rates of mastitis pathogens isolated from the 691 subclinical mastitis udders were as followed: Streptococcus spp 49.0%(300/612), Staphylococcus spp 33.6%(206/612) , Gram-negative bacilli 11.4%(70/612), Yeast 0.2%(1/612) and other 5.8%(35/612). |
