Abstract

This study examines how the combination of layer breeder age and oxygen concentration in the incubator impacts Chorioallantoic (CAM) vascularization, embryo and chick organs, blood profiles, and organ histology at hatch. Nine hundred (900) eggs from 33 to 50 wk ISA breeders were incubated at different O₂ levels (15%, 17%, and 21%). Results showed significant interactions between breeder age and oxygen levels, affecting liver and heart weights, blood indices, and CAM vascularity. Hypoxic conditions led to adaptive changes in embryonic organs, with notable differences between breeder age groups, suggesting that mild hypoxia can influence compensatory growth, depending on exposure stages.

种鸡年龄和绒毛膜早期缺氧刺激对血管形成、内部器官发育、血液轮廓和雏鸡器官组织学的影响

本研究探讨了蛋鸡种鸡年龄和孵化器中氧气浓度的组合如何影响孵化时的绒毛膜（CAM）血管化、胚胎和雏鸡器官、血液概况和器官组织学。在不同的氧气水平（15%、17% 和 21%）下孵化了九百（900）枚来自 33 到 50 周 ISA 种鸡的蛋。结果表明，种鸡年龄与氧气水平之间存在明显的交互作用，会影响肝脏和心脏重量、血液指数和CAM血管。缺氧条件导致胚胎器官发生适应性变化，不同种鸡年龄组之间存在明显差异，这表明轻度缺氧可影响代偿性生长，具体取决于暴露阶段。

期刊介绍： The Journal of Applied Poultry Research (JAPR) publishes original research reports, field reports, and reviews on breeding, hatching, health and disease, layer management, meat bird processing and products, meat bird management, microbiology, food safety, nutrition, environment, sanitation, welfare, and economics. As of January 2020, JAPR will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. The readers of JAPR are in education, extension, industry, and government, including research, teaching, administration, veterinary medicine, management, production, quality assurance, product development, and technical services. Nutritionists, breeder flock supervisors, production managers, microbiologists, laboratory personnel, food safety and sanitation managers, poultry processing managers, feed manufacturers, and egg producers use JAPR to keep up with current applied poultry research.
