The gastrointestinal microbiota plays a pivotal role in maintaining animal health, immunity and reproductive performances. However, literature about the relationship between microbiota and reproductive performance is limited. The aim of the present study was to determine differences in the intestinal microbiota of broiler breeders with different egg laying rate. A total of 200 AA+ parent broiler breeders (41-week-old) were separated into two groups according to their different egg laying rate [average egg laying rate group (AR: 78.57 ± 0.20%) and high egg laying rate group (HR: 90.79 ± 0.43%). Feed conversion ratio (FCR), ovary cell apoptosis rate (ApoCR) and relative abdominal fat weight were lower ( = 0.01), while the hatchability rate of qualified egg was higher ( = 0.04) in HR group than that in AR group. abundance were lower ( = 0.012) in ileum of HR birds. (genus) in ileum was negatively related to the feed efficiency ( = -0.58, < 0.05), (phylum) and (genus) abundances in cecum were positively related to the egg laying rate (ELR) ( = 0.35 and 0.48, < 0.05), feed efficiency ( = 0.42 and 0.43, < 0.05), while (phylum) and (genus) abundances in cecum were negatively related to the ELR ( = -0.43 and -0.70, < 0.05), feed efficiency ( = 0.54 and 0.48, < 0.05), and positively related to ApoCR ( = 0.46 and 0.47, < 0.05). Our results suggested that microbiota, such as (phylum) and (genus) have positive relationship, while (phylum) (genus) abundances exert negative relationship with broiler breeders' reproductive performances.
胃肠道微生物群在维持动物健康、免疫力和繁殖性能方面起着关键作用。然而，关于微生物群与繁殖性能之间关系的文献有限。本研究的目的是确定不同产蛋率的肉种鸡肠道微生物群的差异。总共200只AA + 父母代肉种鸡（41周龄）根据其不同的产蛋率分为两组[平均产蛋率组（AR：78.57 ± 0.20%）和高产蛋率组（HR：90.79 ± 0.43%）]。与AR组相比，HR组的饲料转化率（FCR）、卵巢细胞凋亡率（ApoCR）和相对腹脂重量较低（P = 0.01），而合格种蛋孵化率较高（P = 0.04）。HR组肉种鸡回肠中[某菌属]丰度较低（P = 0.012）。回肠中[某菌属（属）]与饲料效率呈负相关（r = -0.58，P < 0.05），盲肠中[某菌门]和[某菌属]丰度与产蛋率（ELR）呈正相关（r = 0.35和0.48，P < 0.05）、饲料效率呈正相关（r = 0.42和0.43，P < 0.05），而盲肠中[另一菌门]和[另一菌属]丰度与ELR呈负相关（r = -0.43和-0.70，P < 0.05）、饲料效率呈负相关（r = 0.54和0.48，P < 0.05），且与ApoCR呈正相关（r = 0.46和0.47，P < 0.05）。我们的结果表明，微生物群，如[某菌门]和[某菌属]具有正相关关系，而[另一菌门]和[另一菌属]丰度与肉种鸡的繁殖性能呈负相关关系。
