奶牛初乳防治胎衣不下的效果

Efects of Dairy Cow Colostrum on the Prevention of Retention of Fetal Membrane

126头中国荷斯坦奶牛分娩后3～6h颈部两侧皮下注射健康奶牛初乳各25ml,研究初乳防治奶牛RFM的效果。结果表明,试验组126头奶牛的RFM发病率为6.35%,显著低于对照组(P<0.05);试验组71头经产牛RFM发病率为11.27%,显著低于对照组(P<0.05),而试验组55头初产牛RFM发病率与对照组差异不显著(P>0.05)。利用奶牛初乳防治RFM的效果显著,经产牛的效果优于初产牛。

Injected respectively hypodermically 25 ml colostrum of healthy dairy cattles into both sides of neck of Holstein dairy cows 3~6 h after parturition. The aim was to study the effects of dairy cow colostrum on the prevention of retention of fetal membrane （RFM）. The results showed that the incidence of RFM of 126 dairy cow of the experimental group was obviously lower than that of the control group （P〈0.05）. The incidence of RFM of multiparous dairy cows of the experimental group was obviously lower than that of the control group, but it was not obvious for the primiparous dairy cows. The conclusion is that the effect of dairy cow colostrum on the prevention of RFM is significant and the effects on multiparous dairy cowse were much better than that of the primiparous dairy cows.
