This study evaluated the effects of early intervention with () on shaping the intestinal microbiota of Muscovy ducklings. A total of 160 1-day-old male ducks were randomly divided into two groups: the CB group was administered with 1 mL of (2 × 10 CFU/mL), while the C group was given 1 mL of saline. The administration lasted for 3 days. We found that had no significant effect on growth performance. The results indicated that inoculation with could significantly increase the abundance of genera , _uncultured, and on Day 14 and reduce the abundance of and on Days 1 and 3. Moreover, the CB group ducks had higher concentrations of acetic, propionic, and butyrate in the cecum than the C group. Overall, these results suggest that early intervention with could have positive effects on Muscovy ducks' intestinal health, which might be attributed to the modulation in the intestinal microbial composition and the increased concentrations of short-chain fatty acids (SCFAs). might even have the potential to help the colonization of beneficial bacteria in the intestine microbiota in Muscovy ducks in poultry and other livestock.
本研究评估了用（）进行早期干预对番鸭雏鸭肠道微生物群形成的影响。总共160只1日龄雄性鸭被随机分为两组：CB组给予1 mL（2×10 CFU/mL）的（），而C组给予1 mL生理盐水。给药持续3天。我们发现（）对生长性能没有显著影响。结果表明，接种（）可在第14天显著增加属、未培养菌属和（）属的丰度，并在第1天和第3天降低（）属和（）属的丰度。此外，CB组鸭盲肠中乙酸、丙酸和丁酸的浓度高于C组。总体而言，这些结果表明，用（）进行早期干预可能对番鸭的肠道健康有积极影响，这可能归因于肠道微生物组成的调节和短链脂肪酸（SCFAs）浓度的增加。（）甚至可能有潜力帮助有益细菌在番鸭以及其他家禽和家畜的肠道微生物群中定殖。
