Dietary prebiotics are thought to be potentially important alternatives to antibiotic growth promoters in poultry production because of their beneficial performance and health effects. The administration of dietary prebiotics has been demonstrated to improve animal health, growth performance, and microbial food safety in poultry production. In this study, we evaluated the effects of Saccharomyces-derived prebiotic refined functional carbohydrates (RFC) with yeast culture on growth performance and gastrointestinal and environmental microbiota when administered in-feed and through drinking water to broiler chickens. Broilers were administered 2 doses of prebiotic in-feed through 42 d of production and prebiotic-treated water in the final 72 h. Administration of prebiotic RFC improved ADG and decreased cecal Campylobacter counts, while the high dose also increased final BW. Additionally, significant main effects of prebiotic RFC dose were observed with the high dose improving ADG and ADFI over the finisher phase and final BW. Although the effects were not significant, the prevalence of Campylobacter in the cecum after feed withdrawal was 17% lower when broilers were administered the high prebiotic dose, and recovery of Campylobacter from litter was up to 50% lower when broilers were administered prebiotic RFC. Our results suggest that co-administration of RFC with yeast culture as a prebiotic can be used to improve growth performance and reduce human foodborne pathogens in poultry.

饲喂益生元可提高肉鸡的生长性能并减少病原体定植。

膳食益生元被认为是家禽生产中抗生素生长促进剂的潜在重要替代品，因为它们具有有益的性能和健康影响。已经证明，饲喂益生元可以改善家禽生产中的动物健康、生长性能和微生物食品安全。在这项研究中，我们评估了酵母菌衍生的益生元精制功能性碳水化合物 (RFC) 与酵母培养在饲料中和通过饮用水对肉鸡施用时对生长性能以及胃肠道和环境微生物群的影响。在 42 天的生产和最后 72 小时的益生元处理水中，肉鸡被给予 2 剂益生元饲料。给予益生元 RFC 提高了 ADG 并减少了盲肠弯曲杆菌的数量，而高剂量也增加了最终体重。此外，观察到益生元 RFC 剂量的显着主要影响，高剂量可提高育肥期和最终体重的 ADG 和 ADFI。虽然效果不显着，但当肉鸡服用高剂量益生元时，停食后盲肠中弯曲杆菌的流行率降低了 17%，而当肉鸡服用益生元 RFC 时，从垫料中回收的弯曲杆菌降低了 50%。我们的研究结果表明，RFC 与酵母培养物作为益生元的共同给药可用于改善家禽的生长性能并减少人类食源性病原体。虽然效果不显着，但当肉鸡服用高剂量益生元时，停食后盲肠中弯曲杆菌的流行率降低了 17%，而当肉鸡服用益生元 RFC 时，从垫料中回收的弯曲杆菌降低了 50%。我们的研究结果表明，RFC 与酵母培养物作为益生元的共同给药可用于改善家禽的生长性能并减少人类食源性病原体。虽然效果不显着，但当肉鸡服用高剂量益生元时，停食后盲肠中弯曲杆菌的流行率降低了 17%，而当肉鸡服用益生元 RFC 时，从垫料中回收的弯曲杆菌降低了 50%。我们的研究结果表明，RFC 与酵母培养物作为益生元的共同给药可用于改善家禽的生长性能并减少人类食源性病原体。
