Abstract

The removal of antibiotic growth promoters from poultry diets has driven research into alternative feed additives to optimize production performance in laying hens. Among these alternatives, dietary organic acids (OAs) have gained significant attention due to their antimicrobial properties, ability to modulate intestinal acidity, and role in enhancing nutrient utilization. This review comprehensively examines the effects of OAs supplementation on egg production and quality, blood parameters, intestinal morphology, fecal and intestinal microbiota, and bone health in laying hens. Studies indicate that various OAs supplementation improves egg production and quality. Additionally, OAs contribute to superior eggshell quality by enhancing calcium and protein absorption. The physiological benefits of OAs supplementation include improved intestinal morphology, gut microbiota, and immune and physiological responses. On the other hand, the effectiveness of OAs varies depending on the type of acid, dosage, environmental conditions, and interactions with feed ingredients or additives. This review consolidates current findings to provide practical insights into the application of OAs as a viable alternative to AGPs in commercial laying hen production.

饲粮有机酸在蛋鸡生产中的应用综述。

从家禽日粮中去除抗生素生长促进剂推动了对替代饲料添加剂的研究，以优化蛋鸡的生产性能。在这些替代品中，膳食有机酸（OAs）因其抗菌特性、调节肠道酸度的能力和提高营养物质利用的作用而受到广泛关注。本文综述了蛋鸡饲粮中添加oa对蛋鸡产蛋量和品质、血液参数、肠道形态、粪便和肠道微生物群以及骨骼健康的影响。研究表明，各种补充脂肪酸可以提高鸡蛋产量和品质。此外，oa通过促进钙和蛋白质的吸收，有助于提高蛋壳质量。补充oa的生理益处包括改善肠道形态、肠道微生物群以及免疫和生理反应。另一方面，OAs的有效性取决于酸的类型、用量、环境条件以及与饲料成分或添加剂的相互作用。这篇综述整合了目前的研究结果，为在商业蛋鸡生产中应用oa作为agp的可行替代品提供了实际的见解。

期刊介绍： Journal of Animal Science and Technology (J. Anim. Sci. Technol. or JAST) is a peer-reviewed, open access journal publishing original research, review articles and notes in all fields of animal science. Topics covered by the journal include: genetics and breeding, physiology, nutrition of monogastric animals, nutrition of ruminants, animal products (milk, meat, eggs and their by-products) and their processing, grasslands and roughages, livestock environment, animal biotechnology, animal behavior and welfare. Articles generally report research involving beef cattle, dairy cattle, pigs, companion animals, goats, horses, and sheep. However, studies involving other farm animals, aquatic and wildlife species, and laboratory animal species that address fundamental questions related to livestock and companion animal biology will also be considered for publication. The Journal of Animal Science and Technology (J. Anim. Technol. or JAST) has been the official journal of The Korean Society of Animal Science and Technology (KSAST) since 2000, formerly known as The Korean Journal of Animal Sciences (launched in 1956).
