The experiment was conducted to evaluate the effect of onion (Allium cepa L.,) on the performance, gut microflora and intestinal histomorphology of broiler chicks. Three hundred and twenty day old broiler chicks (Ross) were randomly divided into four groups as A, B, C and D. Group A served as control without any supplementation, group B, C and D was supplemented with onion powder at the rate of 1.5, 2 and 2.5g/kg of feed respectively. Supplementation of onion significantly (P<0.05) increased weight gain and feed consumption. Supplementation of onion showed a significant (P<0.05) reduction in the population of E. coli and increased significantly Lactobacillus and Streptococcus species. Onion supplementation significantly (P<0.05) increased the morphometry of length, width, crypt depth and surface area of the villus in duodenum, jejunum and ileum of the small intestine. In conclusion, onion supplementation in broiler produced a positive effect on performance, gut microflora and intestinal histomorphology.
本试验旨在评估洋葱（Allium cepa L.）对肉仔鸡生产性能、肠道微生物群和肠道组织形态学的影响。320只1日龄肉仔鸡（罗斯品种）被随机分为A、B、C和D四组。A组作为对照组，不添加任何物质，B、C和D组分别以1.5、2和2.5g/kg饲料的比例添加洋葱粉。添加洋葱显著（P<0.05）提高了体重增加和采食量。添加洋葱显著（P<0.05）减少了大肠杆菌数量，并显著增加了乳酸杆菌和链球菌数量。添加洋葱显著（P<0.05）增加了小肠十二指肠、空肠和回肠绒毛的长度、宽度、隐窝深度和表面积的形态学指标。总之，在肉仔鸡日粮中添加洋葱对生产性能、肠道微生物群和肠道组织形态学产生了积极影响。
