鸡肠道微生物区系在鸡的健康和生产中起着重要作用,对其发展的更多了解可能会导致采取干预措施来改善鸡的营养、抗病和福利。在本研究中,我们研究了从孵化到5 周龄(1、3、7、14和5周龄)雏鸡的十二指肠、空肠、回肠和盲肠的微生物区系。从肠道内容物中提取DNA,扩增16S rRNA基因V4区,并进行序列测定。我们发现从鸡肠道内不同位置采集的样品在微生物群落组成、多样性和丰富度方面存在显著差异。我们还表征了随着时间的推移每个肠道部位的微生物区系的发展。我们的研究建立在现有文献的基础上,以进一步描述鸡肠道微生物区系的发展。
The chicken intestinal microbiota plays a large role in chicken health and productivity and a greater understanding of its development may lead to interventions to improve chicken nutrition, disease resistance and welfare. In this study we examine the duodenal, jejunal, ileal and caecal microbiota of chickens from day of hatch to 5 weeks of age (day 1, 3, 7, 14 and week 5). DNA was extracted from intestinal content samples and the V4 region of the 16S rRNA gene was amplified and sequenced. We identified significant differences in microbial community composition, diversity and richness between samples taken from different locations within the chicken intestinal tract. We also characterised the development of the microbiota at each intestinal site over time. Our study builds upon existing literature to further characterise the development of the chicken intestinal microbiota.
