The increasing emergence and spread of antibiotic resistance accelerate the desire for antibiotic alternatives. Plant extracts have emerged as a promising and relatively unexplored area of research as potential substitutes. Herein, we investigated the prevalence and distribution patterns of bacteria on egg surfaces and evaluated the inhibitory effects of mangosteen extract on these surface bacteria. In addition, we examined the antioxidant activity and egg quality in improving the ability of mangosteen extract. The results showed that the predominant bacteria isolated from eggshells were Gram-positive, with and as the dominant genera. Notably, mangosteen extract exhibited significant bactericidal activity, effectively inhibiting Gram-positive bacteria on the surface of chicken eggshells. Moreover, the supplementation of mangosteen extract in the feed of laying hens yielded a noteworthy improvement in egg quality, accompanied by positively shaped structure and function of microbial communities on the egg surface and in the feces. Collectively, our findings suggested that mangosteen extract was an effective alternative to traditional antibiotics, offering valuable insights for animal husbandry development.
抗生素耐药性的不断出现和传播加速了对抗生素替代品的需求。植物提取物作为潜在替代品已成为一个有前景且相对未被充分探索的研究领域。在此，我们调查了鸡蛋表面细菌的流行情况和分布模式，并评估了山竹提取物对这些表面细菌的抑制作用。此外，我们还检测了山竹提取物在改善抗氧化活性和鸡蛋品质方面的能力。结果表明，从蛋壳分离出的主要细菌为革兰氏阳性菌，其中 和 为优势菌属。值得注意的是，山竹提取物表现出显著的杀菌活性，能有效抑制鸡蛋壳表面的革兰氏阳性菌。此外，在蛋鸡饲料中添加山竹提取物可显著改善鸡蛋品质，同时使鸡蛋表面和粪便中的微生物群落结构和功能呈正向变化。总体而言，我们的研究结果表明山竹提取物是传统抗生素的有效替代品，为畜牧业发展提供了有价值的见解。
