The fecal microbiota plays an important role in maintaining animal health and is closely related to host life activities. In recent years, there have been an increasing number of studies on the fecal microbiota from birds. An exploration of the effects of species and living environments on the composition of gut microbiota will provide better protection for wildlife. In this study, non-injury sampling and 16S rDNA high-throughput sequencing were used to investigate the bacterial composition and diversity of the fecal microbiota in silver pheasants () and golden pheasants () from Tianjin Zoo and Beijing Wildlife Park. The results showed that the abundance of Firmicutes was the highest in all fecal samples. At the genus level, was the common dominant bacteria, while there were some differences in other dominant bacteria genera. There were significant differences in fecal microbial composition between the golden pheasants from Tianjin Zoo and Beijing Wildlife Park. The metabolic analysis and functional prediction suggested that the gut microbiota composition and host metabolism were influenced by dietary interventions and living conditions. The results of this study provide the basis for further research of intestinal microbial of and , and valuable insights for conservation of related species.
粪便微生物群在维持动物健康方面发挥着重要作用，与宿主的生命活动密切相关。近年来，关于鸟类粪便微生物群的研究越来越多。探索物种和生活环境对肠道微生物组成的影响，将为野生动物提供更好的保护。本研究采用非损伤性采样和 16S rDNA 高通量测序技术，对天津动物园和北京野生动物园的银雉（）和金雉（）粪便微生物群的细菌组成和多样性进行了研究。结果表明，所有粪便样本中厚壁菌门的丰度最高。在属水平上，是常见的优势菌属，而其他优势菌属存在一些差异。天津动物园和北京野生动物园的金雉粪便微生物组成存在显著差异。代谢分析和功能预测表明，饮食干预和生活条件影响肠道微生物组成和宿主代谢。本研究结果为进一步研究和 的肠道微生物提供了基础，并为相关物种的保护提供了有价值的见解。
