摘要

本试验旨在研究断奶日龄对湖羊羔羊瘤胃微生物多样性的影响。选择66只湖羊公羔,在羔羊1、14、28日龄各屠宰6只羔羊,剩余48只羔羊随机分为2组,分别于28和56日龄断奶,在42、56、70和84日龄每组屠宰6只羔羊,取瘤胃内容物样品。所有羔羊7日龄开始饲喂开食料。试验期为羔羊1~84日龄。结果表明:断奶日龄对白色瘤胃球菌(Ruminococcus albus)、黄色瘤胃球菌(Ruminococcus flavefaciens)、牛链球菌(Streptococcus bovis)、产琥珀酸丝状杆菌(Fibrobacter succinogenes)和布氏密螺旋体(Treponema bryantii)的相对丰度无显著影响(P>0.05)。随着日龄增加,羔羊瘤胃微生物多样性不断增加,28日龄断奶的羔羊相对56日龄断奶的羔羊其瘤胃微生物多样性提高。结果提示,瘤胃微生物多样性受日龄和断奶日龄的影响,早期断奶可加速瘤胃微生物区系的建立。

Abstract

The aim of the present study was to evaluate the weaning days of age on ruminal microbial diversity in Hu lambs. Sixty-six male Hu lambs were selected, and six lambs were slaughtered at each sample time (1, 14 and 28 days of age, respectively). The rest 48 lambs were divided into two groups weaned at 28 and 56 days of age, respectively. Lambs were slaughtered at 42, 56, 70 and 84 days of age (6 lambs per group at each sample time), respectively, to collect ruminal content. All lambs were fed starter since 7 d of age. The experiment period was from 1 to 84 days of age. The results showed as follow:weaning days of age had no significant effects on the relative abundance of Ruminococcus albus, Ruminococcus flavefaciens, Streptococcus bovis, Fibrobacter succinogenes and Treponema bryantii. With the increase of days of age, ruminal microbial diversity of lambs continuously increased; compared with lambs weaned at 56 days of age, lambs weaned at 28 days of age had higher microbial diversity. The results indicate that the microbial diversity are affected by days of age and weaning days of age, and early weaning can accelerate establishment of ruminal microflora.
