控制性初乳供给对犊牛获取被动免疫的影响
Effect of Controlled Colostrum Supply on Passive Immunization in Calves
摘要
Abstract
Serum immunoglobulin(IgG)levels was measured after 48 h of colostrum feeding.If the IgG level was more than 10 mg/mL,it indicates that the calf has acquired better immunity.To investigate the effect of colostrum supply on passive im-mune transfer(TPI)in newborn calves,72 newborn calves were selected to conduct a controlled feeding experiment with colos-trum feeding time period,feeding amount,feeding mode and colostrum quality as variables,to analyze the effect of colostrum control supply on TPI acquisition in newborn calves.The results showed that,under the premise of feeding high-quality colos-trum,good IgG levels could be obtained within 1-2 h after calves were born,at 10％of calves'body weight colostrum,using pasteurized colostrum(LTLT),and feeding via a bottle can all result in better IgG levels,reaching 13.53,14.76,20.39 and 14.97 mg/mL respectively,all surpassing the threshold of 10 mg/mL.The IgG value reached 21.07 mg/mL after inputting the a-bove four variables,which indicated that the control colostrum supply had a significant effect on TPI acquisition in newborn calves.关键词
