A study was carried out to assess the efficacy of prebiotic delivered in ovo on performance, carcass traits, meat quality and gut health in the face of a natural coccidiosis infection in Kuroiler chickens. On d 12 of incubation, 150 fertile eggs were divided into a prebiotic group injected with trans-galactooligosaccharides (Bitos) and a control group uninjected. Hatched chicks from each group were further divided: One group received antibiotic chick formula while the other was left untreated, giving rise to 4 groups-Control (C), Antibiotic (A), Bitos (B), and Bitos + Antibiotic (AB). Prebiotic improved growth performance at six weeks of age, AB birds were the heaviest at the end of the rearing period. The highest intestinal lesion scores and oocyst counts were recorded in C birds. B group had a slightly higher carcass weight and cuts yields tended to be higher in treated groups compared to C. Meat from B group displayed a higher amount of polyunsaturated fatty acids compared to C and a positively lower n-6/n-3 ratio compared to C and A. In conclusion, prebiotics with or without antibiotics reduced severity of intestinal lesions and oocyst excretion induced by natural infection with , with positive effects on Kuroiler chicken productive traits.
开展了一项研究，以评估在面对黑羽肉鸡自然感染球虫病的情况下，在蛋内递送益生元对其生产性能、胴体性状、肉质和肠道健康的影响。在孵化第12天，将150枚受精蛋分为注射低聚半乳糖（Bitos）的益生元组和未注射的对照组。每组孵化出的雏鸡进一步分组：一组接受抗生素雏鸡配方饲料，另一组不进行处理，从而产生4组——对照组（C）、抗生素组（A）、Bitos组（B）和Bitos+抗生素组（AB）。益生元改善了6周龄时的生长性能，在饲养期结束时，AB组的鸡最重。C组鸡的肠道病变评分和卵囊计数最高。与C组相比，B组的胴体重量略高，处理组的切块产量往往更高。与C组相比，B组鸡肉中多不饱和脂肪酸含量更高，与C组和A组相比，n-6/n-3比值更低。总之，无论有无抗生素，益生元都降低了自然感染引起的肠道病变严重程度和卵囊排泄量，对黑羽肉鸡的生产性状有积极影响。
