初乳中免疫球蛋白含量对羔羊被动免疫、生长性能及健康情况的影响
Effect of Immunoglobulin Content in Colostrum on Passive Immunity,Growth Performance and Health of Lambs
摘要
Abstract
The study evaluated the effects of immunoglobulin(Ig)content in colostrum on passive im-munity,growth performance,and health status of Saanen dairy goat(Capra hircus L.)lambs.Forty new-born lambs were selected and divided into three groups based on the average IgG,IgM,and IgA concentra-tions in the colostrum they ingested:high-quality colostrum group(HC),good-quality colostrum group(GC),and ordinary colostrum group(OC).The lambs were artificially fed with colostrum corresponding to their respective groups.The study compared and analyzed serum immunoglobulin levels,daily weight gain,and health conditions among the groups.The results showed that the serum immunoglobulin levels in the HC group were significantly higher(P＜0.05)within 24 hours post-ingestion compared to the other groups.Additionally,the morbidity and mortality rates in the HC group were significantly lower(P＜0.05)during the subsequent observation period.However,no significant differences were observed in daily weight gain among the groups(P＞0.05).These results indicate that the immunoglobulin content in colos-trum has a significant impact on the early passive immune status of goat lambs and can positively influence their survival rate,although it has little effect on the growth performance.关键词
