试验旨在探究党参黄芪粗提物(CAE)对三黄鸡生长性能、血清生化指标、免疫器官指数及肠道形态的影响.选取初重(27.0±0.5)g、生理状态良好的1日龄广西三黄鸡360羽,随机分为3组,每组6个重复,每个重复20只鸡.CON组饲喂基础饲粮,CAE组饲喂基础饲粮+2.5 g/kg党参黄芪粗提物,ANT组饲喂基础饲粮+0.05 g/kg金霉素.试验期42 d.结果显示,与CON组相比,CAE组和ANT组三黄鸡的末重和平均日增重显著升高(P＜0.05),料重比显著降低(P＜0.05),死淘率降低3.33％(P＞0.05).与CON相比,CAE组和ANT组血清中谷草转氨酶活性及甘油三酯、胆固醇含量显著降低(P＜0.05).与CON相比,CAE组和ANT组法式囊指数显著升高(P＜0.05).与CON相比,CAE组、ANT组十二指肠绒毛高度和绒隐比显著升高(P＜0.05).研究表明,党参黄芪粗提物对三黄鸡生长性能、血清生化指标、免疫器官指数和肠道形态的改善均有不同程度的改善作用,与抗生素的应用效果相当.
Effects of crude extract of Codonopsis pilosula and Astragalus membranaceus on growth performance and intestinal morphology of Sanhuang chickens
The purpose of this experiment was to explore the effects of crude extract of Codonopsis pilosula and Astragalus membranaceus(CAE)on growth performance,serum biochemical index,immune organ index,and intestinal morphology of Sanhuang chickens.A total of 360 one-day-old Guangxi Sanhuang chicks weighing(27.0±0.5)g and in good physiological condition were randomly divided into three groups with six replicates in each group and 20 chickens in each replicate.CON group was fed a basal diet,CAE group was fed basal diet with 2.5 g/kg crude extract of Codonopsis pilosula and Astragalus membranaceus,and ANT group was fed basal diet with 0.05 g/kg chlortetracycline.The trial period was 42 days.The results showed that compared with CON group,the final weight and average daily gain of CAE group and ANT group increased significantly(P＜0.05),the feed-to-weight ratio decreased significantly(P＜0.05),and the mortality rate decreased by 3.33％(P＞0.05).Compared with CON group,the activity of aspartate aminotransferase and the content of triglyceride and cholesterol in serum of CAE group and ANT group decreased significantly(P＜0.05).Compared with CON group,CAE group and ANT group had significantly higher French capsule index(P＜0.05).Compared with CON group,the villus height and villus-saphenous ratio of twelve intestines in CAE group and ANT group were significantly higher(P＜0.05).The study indicates that the crude extract of Codonopsis pilosula and Astragalus membranaceus has positive effects on the growth performance,serum biochemical index,immune organ index and intestinal morphology of Sanhuang chickens,which was equivalent to the application effect of antibiotics.
