地顶孢霉培养物对泌乳期母羊泌乳性能及其子代羔羊生长性能的影响
Effects of Acremonium terricola culture on lactation performance of lactating ewes and growth performance of their offspring lambs
摘要
Abstract
The experiment aimed to investigate the effects of Acremonium terricola culture(ATC)on the lactation performance of lactating ewes,as well as the growth performance,serum biochemical,immune,and antioxidant indices of their offspring lambs.A total of 18 Hu sheep ewes with the same parity,body weight of(42.5±2.5)kg,good health status on the day of delivery,and their 36 lambs were randomly divided into two groups,with three replicates per group,each replicate had three ewes and their six lambs.The control group(group CON)was fed a basal diet,while the experimental group(group ATC)was fed the basal diet supplemented with 9 g/d ATC per ewe.The test period lasted for 42 days.The results showed that there were no significant differences in various growth performance indices of ewes and lambs between groups ATC and CON(P>0.05),but the average daily gain of lambs in group ATC was higher than that in group CON.No significant differences were observed in the concentrations of milk fat,milk protein,lactose,total solids,and urea nitrogen in the milk between the two groups(P>0.05).However,the content of immunoglobulin A(IgA)in the milk of group ATC was significantly higher than that of group CON(P<0.05).The serum concentrations of glucose(GLU)and IgA in lambs from group ATC were significantly higher than those in group CON(P<0.05).No significant differences were found in other serum indices of lambs between the two groups(P>0.05).Correlation analysis indicated that in group ATC,the milk concentrations of IgA and immunoglobulin M(IgM)of ewe were significantly positively correlated with the serum concentrations of IgA,immunoglobulin G(IgG),and IgM in lambs(P<0.05).In group CON,the milk IgA content of ewes was significantly positively correlated with the serum IgA content of lambs(P<0.05).The study shows that dietary ATC supplementation does not affect the growth performance and milk yield of lactating ewes,but it can increase the immunoglobulin content in milk to some extent,while having a limited effect on the growth performance and immune function of suckling lambs.关键词
