摘要/Abstract

摘要： 动物初乳对其后代健康的作用已经得到了广泛的证实,其对人类健康的影响也受到了越来越多的重视。本研究探讨了阿尔卑斯山羊产后一周内乳成分和其中免疫球蛋白(Ig)含量的变化。结果表明:产后48h内山羊奶的蛋白质、总固形物和免疫球蛋白含量均快速下降;脂肪含量在前三次的初乳中逐渐升高,随后又缓慢下降;乳糖含量保持相对稳定于4%～5%;经产山羊前三次初乳的蛋白含量分别达到了16.5%、10.7%和6.8%,显著地高于初产山羊前三次初乳的蛋白含量(7.0%、4.8%和4.1%);经产山羊前两次初乳的IgG含量达到了59.9mg/ml和34.7mg/ml,IgM含量达到了6.14mg/ml和2.37mg/ml,显著地高于初产山羊前两次初乳的IgG含量(18.1mg/ml和13.9mg/ml)和IgM含量(1.95mg/ml和0.98mg/ml);经产和初产山羊初乳的IgA含量无显著差异。

Abstract: The benefits of animal colostrum to its neonates have been widely documented and more attention has been paid to its benefit to human health. In this study, the changes of composition and Immunoglobulin (Ig) content in milk of Alpine goats 1 week after parturition were investigated. The results showed that the content of protein, total solids and Ig in goat milk decreased sharply 48 h after parturition; The content of fat in first three milk increased and then decreased slowly; The content of lactose fluctuated between 4% and 5%; The content of protein in first three milk of primiparous goats was 16.5%, 10.7% and 6.8%, respectively, higher than those in first three milk of multiparous goats (7.0%, 4.8% and 4.1%); The content of IgG in first two milk of primiparous goats was 59.9 mg/ml and 34.7 mg/ml, and IgM was 6.14 mg/ml and 2.37 mg/ml, respectively, higher than those in first two milk of multiparous goats (IgG was 18.1 mg/ml and 13.9 mg/ml and IgM was 1.95 mg/ml and 0.98 mg/ml, respectively); No significant difference of IgA content in milk of primiparous and multiparous goats was found.
