| 摘 要： | 对佳木斯市4所奶牛场进行流行病学调查,研究临床型乳腺炎和隐性乳腺炎的发病率以及病因。对4所奶牛场的390头泌乳牛进行检测,其中218头患有隐性型乳腺炎,头发病率为55.90%;17头患有临床型乳腺炎,头发病率为4.43%;乳腺炎的头发病率为60.26%。在被检的1416个有效乳区中,患有隐性型乳腺炎的乳区有792个,乳区阳性率为55.93%;患有临床型乳腺炎的乳区有20个,乳区阳性率为1.41%。对牛场圈舍条件和生产、管理诸环节调查分析表明,引起奶牛乳腺炎的主要原因为饲养管理水平较低、饲料品质较低、挤奶工不能严格遵守无菌操作、高产奶牛乳头未开展干奶期预防工作等。 |

| Abstract: | Aim to make an investigation on the incidence of bovine subclinical and clinical mastitis and to find out the pathogeny by epidemiology in Jiamusi city. The investigation showed, for the 390 milk cows on 4 dairy farms, there were 218 cows with type subclinical mastitis in the investigation of the 4 dairy farms (total 390), incidence rate was 55.90%; there were 17 cows with clinical mastitis, incidence rate was 4.43%, the incidence of mastitis was 60.26%. In the 1 416 milk areas , the subclinical mastitis milk area was 792, and the positive rate was 55.93%, with the clinical mastitis milk area in dairy was 20, the positive rate breast area was 1.41%. By epidemiology investigation, the major pathogeny of these bovine mastitis was found out to be the lower level of feeding management, the poor quality feed stuff, unstrict aseptic manipulation and the nipple infection prevention work for high producing dairy cow was not carried out during the dry period. |
