The current research aimed to evaluate the supplemental effects of iron oxide nanoparticles (IONPs) on production performance, viscera development, blood metabolites, redox status, meat quality, and jejunal histology in broilers. A total of 300 day-old broilers were randomly divided into six groups with five replicates per group. Birds were fed on a corn soybean-based diet supplemented with 0, 20, 40, 60, or 80 mg/kg IONPs or 80 mg/kg of FeSO for 35 days. The feed conversion ratio (FCR) was improved in birds supplemented with 60 mg/kg IONPs. The pH was lower in birds supplemented with 40 mg/kg IONPs compared to that of the bulk group. Pectoral muscle fascicle diameter and fiber density were significantly increased in 20 mg/kg IONP-supplemented birds compared to those of the bulk group, respectively. The muscle fiber diameter was higher in 40 mg/kg IONP-supplemented birds compared with the bulk group. The jejunal villus height, crypt depth, and villus surface area were significantly increased with 60 mg/kg IONP supplementation, whereas villus width was decreased in birds supplemented with 40 mg/kg IONPs. The villus-height-to-crypt-depth ratio was lower in IONP-supplemented birds compared to the bulk group. IONP supplementation improved the FCR, jejunal, and pectoral muscle morphology without affecting the carcass characteristics and redox status of broilers.
当前的研究旨在评估氧化铁纳米颗粒（IONPs）对肉鸡生产性能、内脏发育、血液代谢物、氧化还原状态、肉质和空肠组织学的补充作用。总共300只1日龄肉鸡被随机分为六组，每组五个重复。给鸡喂食以玉米大豆为基础的日粮，分别添加0、20、40、60或80毫克/千克的IONPs或80毫克/千克的硫酸亚铁，持续35天。补充60毫克/千克IONPs的鸡的饲料转化率（FCR）得到改善。与对照组相比，补充40毫克/千克IONPs的鸡的pH值较低。与对照组相比，补充20毫克/千克IONPs的鸡的胸肌束直径和纤维密度分别显著增加。与对照组相比，补充40毫克/千克IONPs的鸡的肌纤维直径更高。补充60毫克/千克IONPs显著增加了空肠绒毛高度、隐窝深度和绒毛表面积，而补充40毫克/千克IONPs的鸡的绒毛宽度降低。与对照组相比，补充IONPs的鸡的绒毛高度与隐窝深度之比更低。补充IONPs改善了肉鸡的FCR、空肠和胸肌形态，而不影响其胴体特性和氧化还原状态。
