摘　　要：文章旨在分析发酵玉米蛋白粉对肉鸡生长性能、免疫器官指数及肠道组织形态的影响。试验以1日龄AA肉鸡为研究对象,共分为4组,对照组根据《鸡饲养标准》设计基础日粮,其余3组在等氮条件下分别添加10%、20%、30%发酵玉米蛋白粉,每组5个重复,每个重复10羽,总计200羽。试验为期21d。结果表明,(1)发酵玉米蛋白粉添加水平为20%时,肉鸡末重显著提高8.29%(P<0.05),平均日增重显著提高了8.90%(P<0.05),料重比显著降低了8.67%(P<0.05)。(2)不同水平发酵玉米蛋白粉均可显著提高肉鸡的胸腺指数和法氏囊指数(P<0.05)。(3)不同水平发酵玉米蛋白粉均可显著提高肉鸡十二指肠的绒毛高度、绒隐比(P<0.05),回肠的绒毛高度、绒隐比(P<0.05)。结论 :基础日粮添加发酵玉米蛋白粉可提高肉鸡的生长性能和免疫器官指数,改善肠道组织形态,其中发酵玉米蛋白粉添加水平为20%时效果最佳。To analyze the effects of fermented corn protein powder on the growth performance,immune organ index,and intestinal tissue morphology of broiler chickens.The experiment focused on 1-day AA broiler chickens and divided them into 4 groups.The control group was designed with a basic diet according to the Chicken Feeding Standards,while the other 3 groups were added with 10%,20%,and 30%fermented corn protein powder under equal nitrogen conditions.Each group had 5 replicates,with 10 chickens per replicate,totaling 200 chickens.The test lasted for 21 days.The results showed that,(1)When the addition level of fermented corn protein powder was 20%,the final weight of broiler chickens significantly increased by 8.29%(P<0.05),the average daily weight gain significantly increased by 8.90%(P<0.05),and the feed to weight ratio significantly decreased by 8.67%(P<0.05).(2)Different levels of fermented corn protein powder significantly increased the thymus index and bursal index of broiler chickens(P<0.05).(3)Different levels of fermented corn protein powder significantly increased the villus height and villus to fat ratio(P<0.05)in the duodenum of broiler chickens,as well as the villus height and villus to fat ratio(P<0.05)in the ileum.Conclusion:Adding fermented corn protein powder to the basic diet can improve the growth performance and immune organ index of broilers,improve intestinal tissue morphology,and the best effect is achieved when the addition level of fermented corn protein powder is 20%.
