摘要(Abstract)：

【目的】寻找林麝养殖母幼分离最佳时间、提高母麝繁殖效率及效益。【方法】采用时间序列试验设计，在断奶前1个月、断奶前半个月、断奶后半个月、断奶后1个月采集粪便。应用16S rRNA高通量测序技术，对8只母麝粪便菌群构成进行分析。【结果】Alpha多样性结果显示，母幼分离后半个月肠道菌群Shannon多样性显著降低(P<0.05)。Beta多样性分析显示，母幼分离会增加肠道菌群组成偏离正常情况的个体的数量，1个月后，受到干扰的个体有逐渐恢复原状。在门水平上，母幼分离前后林麝母麝肠道菌群优势菌门为厚壁菌门和拟杆菌门。分离后半个月疣微菌门占比增多，蓝细菌相对丰度显著增加(P<0.05)。【结论】母幼分离会降低肠道菌群的均匀度及丰富度，引起肠道菌群构成的差异，影响母麝健康。在养殖过程中母幼分离应注意循序渐进，减少母幼分离对林麝肠道菌群平衡的影响。
