Analysis of the intestinal microbiota and physiological parameters in mammalian infancy can reveal health status. In this study, we used a combination of molecular and immunochemical approaches to assess fecal microbiota as well as Cortisol (Cor), Triiodothyronine (T3), and immunoglobulin A (IgA) levels of young forest musk deer (FMD), from birth to one month after weaning (7 days of age–110 days of age). During development as the diet of FMD changes from consuming milk to eating plants, the richness and diversity of intestinal microbiota of young FMD increased significantly. Cor levels remained unchanged throughout early development while significantly increased after weaning, T3 and IgA initially were derived from milk during lactation, significantly decreased after weaning. Correlation network analysis showed that the community of food‐oriented microbes were highly structured and that many genera were correlated. Overall, this study provides scientific insights into effective management strategies for the protection of FMD population.

从出生到断奶的森林麝鹿(Moschus berezovskii)的肠道菌群和粪便皮质醇,T3和IgA的特征

对哺乳动物婴儿时期肠道菌群和生理参数的分析可以揭示健康状况。在这项研究中,我们使用了分子和免疫化学方法的组合来评估从出生到出生的幼林麝(FMD)的粪便微生物群以及皮质醇(Cor),三碘甲状腺素(T3)和免疫球蛋白A(IgA)的水平断奶后一个月(7天至110天)。在发育过程中,随着口蹄疫的饮食从食用牛奶变为食用植物,幼年口蹄疫的肠道菌群的丰富性和多样性显着增加。Cor水平在整个早期发育过程中保持不变,但在断奶后显着增加,T3和IgA最初是在哺乳期从牛奶中产生的,在断奶后显着下降。相关网络分析表明,以食物为导向的微生物群落具有高度结构性,并且许多属具有相关性。总体而言,本研究为保护口蹄疫人口的有效管理策略提供了科学见解。
