The present study was carried to ascertain the association of various risk factors of mastitis in water buffaloes. The milk samples from buffaloes were collected and screened through California Mastitis Test for the presence of mastitis. In the present study, 15.2 % prevalence of subclinical mastitis was recorded both at the government (13.4 %) and private farms (15.5 %). The chi-square analysis showed significantly higher involvement of the right rear and front quarters. The analysis of variance technique showed significant difference in live body weight, milk yield, teat end to floor distance (P < 0.001), udder depth, teat length, and teat diameter in mastitic and healthy buffaloes. The frequency analysis also revealed significant difference between various groups including lactation stage, teat and/or udder pathology, teat shape, and udder shape (P < 0.001). The logistic regression analysis revealed significant positive association of mastitis with milk leakage, live body weight, milk yield, parity, calf suckling, pendulous udder, number of attendants at the farm, dirty hind legs, and udder depth.
本研究旨在确定水牛乳腺炎各种风险因素之间的关联。采集了水牛的牛奶样本,并通过加利福尼亚乳腺炎检测法对乳腺炎的存在情况进行筛查。在本研究中,政府养殖场(13.4%)和私人养殖场(15.5%)的亚临床乳腺炎患病率均为15.2%。卡方分析显示右后乳腺和前乳腺的受累情况显著更高。方差分析技术表明,患乳腺炎的水牛和健康水牛在活体体重、产奶量、乳头末端到地面的距离(P<0.001)、乳房深度、乳头长度和乳头直径方面存在显著差异。频率分析还显示,在泌乳阶段、乳头和/或乳房病理学、乳头形状和乳房形状等不同组之间存在显著差异(P<0.001)。逻辑回归分析显示,乳腺炎与乳汁泄漏、活体体重、产奶量、胎次、犊牛哺乳、乳房下垂、养殖场护理人员数量、后腿脏污以及乳房深度之间存在显著正相关。
