两种不同类型的牛床对奶牛产科疾病影响的研究

本试验比较了木板地面和混凝土地面的牛床对奶牛产科疾病的不同影响。结果显示,新建的两种牛床奶牛产科疾病发病率,混凝土地面低于木地板,差异不显著。经过1年时间后,木板地面牛床的发病率明显高于混凝土地面牛床,差异显著(P<0.05),发病率分别为38.24%和25.00%。木板牛床患病淘汰头数明显增多,其中,胎衣不下、产后感染、乳房炎发病情况特别明显,两种地面差异极显著(P<0.01)。高温季节,发病率木地板高于混凝土地面,差异显著(P<0.05)。结果证实:减少奶牛产科疾病,混凝土地面要优于木板地面。

Study on the Influence of Two Kinds of Cow''''s Bed to Cow''''s Obstetric Disease

By comparing to the different effects to cow's obstetric disease in b oard and cement of cow's bed,the results showed that the difference was not obvi ous because the pathogency efficience of cow's obstetric disease in cement floor was lower than its in board floor. But after one year, the result was on the co ntrary any the difference was obvious(p<0.05). The pathogency efficience were 38 .24%and 25.00%. The quantities of ill and dead cows was increased. The things su ch as the retained fetal membranes ,the puerperal infection, the mastitis were v ery obvious and the discrepancy of two kinds of floors were very obvious. The di screpancy(p<0.05) was also obvious when the pathogency efficience of cow's obste tric disease in board floor was higher than its in cement floor in hot seasons e very year .The paper also showed that in decreasing the cow's obstetric disease, the coment floor was superior to the board floor.
