The aim was to investigate the impact of an automatic in ovo injection of the raffinose family oligosaccharides (RFO) extracted from the seeds of L, on the chicken performance and resistance in a production environment. At day 12 of incubation, a total of 57,900 eggs (Ross 308) were divided into two groups: 1/ Control, injected with 0.9% NaCl and 2/ RFO group, injected with 1.9 mg/egg of the lupin seed extract, dissolved in 0.2 mL NaCl. The performance parameters, biochemical indices (lipid profile, hepatic parameters), gut histomorphology and duodenum structure, oxidative stability of the meat and microbiological counts of the major commensal microbiota species were analyzed. Mortality, body weight, and feed conversion ratio () were not affected. By day 42, several health indices were improved with RFO and were reflected in a beneficial lipid blood profile, increased villi surface and better combating opportunistic pathogens through reduction of and decreased coccidia counts. The RFO increased meat oxidation, but only at the beginning of the storage. The RFO sourced from local legumes can be considered a promising prebiotic for broiler chickens. In ovo delivery of prebiotics and/or synbiotics should be further optimized as an important strategy for the earliest possible modulation of chicken resistance.
目的是研究在生产环境中，对从羽扇豆种子中提取的棉子糖家族低聚糖（RFO）进行自动蛋内注射，对雏鸡生产性能和抵抗力的影响。在孵化第12天，将总共57,900枚鸡蛋（罗斯308）分为两组：1/对照组，注射0.9%氯化钠；2/RFO组，注射溶解于0.2 mL氯化钠中的1.9 mg/枚鸡蛋的羽扇豆种子提取物。分析了生产性能参数、生化指标（血脂谱、肝脏参数）、肠道组织形态学和十二指肠结构、肉的氧化稳定性以及主要共生微生物种类的微生物计数。死亡率、体重和饲料转化率（）未受影响。到第42天，RFO改善了多项健康指标，表现为有益的血脂谱、绒毛表面积增加以及通过降低和减少球虫计数更好地抵抗机会性病原体。RFO增加了肉的氧化，但仅在储存初期。源自当地豆类的RFO可被视为肉鸡有前景的益生元。蛋内递送益生元和/或合生元应作为尽早调节雏鸡抵抗力的重要策略进一步优化。
