Chickens are one of the most economically important poultry species, and their egg-laying performance is a crucial economic trait. The intestinal microbiome plays a significant role in the egg-laying performance. To clarify the diversity of chicken intestinal microbiota and its connection to egg-laying performance, this study utilized 16S rRNA sequencing technology to characterize the intestinal microbiomes of 101 chickens from 13 breeds with varying levels of egg production. The results reveal significant differences in gut microbiota structure among chicken groups with varying egg production levels. High egg-producing chickens showed significantly higher abundances of , , and , while low egg-producing chickens displayed greater microbial α-diversity and more complex community structures. These differences in gut microbiota influence key physiological functions, including nutrient absorption and hormone regulation through metabolic pathways, and directly affect egg production performance. The low and medium production groups partially overlapped on the principal coordinates analysis plot, whereas the high-production group was distinctly separate. This study provides a scientific basis and intestinal microbiome data for selecting probiotics related to high egg production in chickens.
This study elucidates the critical role of gut microbiota in the egg-laying performance of chickens, a key economic indicator in the poultry industry. By employing 16S rRNA sequencing, we uncovered distinct microbial profiles associated with varying levels of egg production. High egg-producing chickens exhibit a higher abundance of specific bacterial taxa, such as and , which are linked to enhanced nutrient absorption and metabolic efficiency. Conversely, lower and medium egg-producing chickens display greater microbial diversity, suggesting a more complex but less efficient gut ecosystem. Our findings provide valuable insights into the relationship between gut microbiota and egg production, offering a scientific foundation for the selection of probiotics that could potentially improve the egg-laying performance of chickens. This research not only advances our understanding of avian gut microbiology but also has practical implications for optimizing poultry farming practices and enhancing economic outcomes.
鸡是经济上最重要的家禽品种之一，其产蛋性能是一项关键的经济性状。肠道微生物群在产蛋性能中起着重要作用。为了阐明鸡肠道微生物群的多样性及其与产蛋性能的联系，本研究利用16S rRNA测序技术对来自13个品种、产蛋水平各异的101只鸡的肠道微生物群进行了特征分析。结果显示，不同产蛋水平的鸡群之间肠道微生物群结构存在显著差异。高产蛋鸡的[具体菌属1]、[具体菌属2]和[具体菌属3]丰度显著更高，而低产蛋鸡则表现出更高的微生物α多样性和更复杂的群落结构。肠道微生物群的这些差异通过代谢途径影响关键生理功能，包括营养吸收和激素调节，并直接影响产蛋性能。在主坐标分析图上，中产蛋组和低产蛋组部分重叠，而高产蛋组则明显分开。本研究为选择与鸡高产蛋相关的益生菌提供了科学依据和肠道微生物群数据。
本研究阐明了肠道微生物群在鸡产蛋性能中的关键作用，产蛋性能是家禽业的一项关键经济指标。通过采用16S rRNA测序，我们发现了与不同产蛋水平相关的独特微生物特征。高产蛋鸡表现出特定细菌类群的丰度更高，如[具体菌属1]和[具体菌属2]，这些与增强的营养吸收和代谢效率有关。相反，中产蛋鸡和低产蛋鸡表现出更大的微生物多样性，表明肠道生态系统更复杂但效率更低。我们的研究结果为肠道微生物群与产蛋之间的关系提供了有价值的见解，为选择可能改善鸡产蛋性能的益生菌提供了科学基础。这项研究不仅推进了我们对鸟类肠道微生物学的理解，而且对优化家禽养殖实践和提高经济效益具有实际意义。
