摘　　要：为了有效地防控奶牛乳房炎,并掌握其发病原因,试验利用一般线性模型,分析了品种、年龄、胎次、泌乳月和采样季节诸因素对奶牛乳房炎的影响。结果发现:乳用牛比乳肉兼用型牛更容易患乳房炎;随着年龄的增长,奶牛乳房炎的发病率上升;在潮湿多雨的季节里,奶牛更容易得乳房炎;随着泌乳月的加大、胎次的升高乳房炎发病率有上升的趋势。The goal of this study was to analyses the factors influencing the bovine mastitis. Breed, age, lactation, month in milk, season and other factors in mastitis of dairy cattle were analyzed using GLM in this study. The results showed that dairy cattle has large probability to get mastitis than duel-Purpose cattle. The incidence of mastitis increased with the increasing of age, month in milk and lactation. Dairy cattle was more easily to get mastitis in damp and rainy seasons.
