摘　　要：本试验旨在研究发酵中药制剂对肉仔鸡免疫机能和抗氧化机能的影响。发酵中药是将中药粉剂(组方为黄芪、贯众、板蓝根、何首乌、山楂、女贞子、艾叶)按比例加入六神曲、淀粉、水混匀,在30℃的生化培养箱中发酵48h制得。为了检测该制剂的使用效果,特做以下试验:180只1日龄雄性AA肉仔鸡随机分为3个处理,每个处理6个重复,每个重复10只鸡,分别饲喂日粮:A组,饲喂基础日粮;B组,饲喂基础日粮+0.5%中药;C组,饲喂基础日粮+0.5%发酵中药。试验结果表明:(1)与空白对照组相比,发酵中药显著提高了3周龄仔鸡胸腺指数(P<0.05)、血清溶菌酶的活性(P<0.05)、6周龄仔鸡血浆谷胱甘肽过氧化物酶的活性(P<0.05),显著降低了6周龄仔鸡腿肌MDA含量(P<0.05);(2)与中药对照组相比,发酵中药显著提高了3周龄仔鸡胸腺指数(P<0.05)、ND抗体水平(P<0.05)。结果表明,发酵中药显著改善肉仔鸡的免疫机能和抗氧化机能,其使用效果优于中药组。The experiment was conducted to study the effects of fermented Chinese herbs on immune function and antioxidant ability of broilers.The traditional Chinese herbs(Astragalus,Dryopteris crassirhizoma,Radix isatidis,Polygonum multiflorum,Fructus crataegi,Ligustrum lucidum,Argy wormwood leaf)were mixed evenly in proportion with medicated leaven,starch and water,then fermented under 30℃for 48 hin biochemical incubator.In order to test the effects of the fermented herbs,animal trial was carried out as follows.180one-day-old male AA broiler chicks were randomly divided into 3treatments,6replicates per treatment,10 birds each replicate.The different treatments were fed the following diets:A group,fed basal diet;B group,fed basal diet+0.5% Chinese herbs;C group,fed basal diet+0.5% fermented Chinese herbs.The results showed that:(1)Compared with A group,fermented Chinese herbs significantly improved the thymus index(P<0.05),serum lysozyme activity of broilers at 3week(P<0.05),improved plasma GSH-Px activity at 6week(P<0.05),decreased MDA content in thigh muscle of broilers at 6week(P<0.05);(2)Compared with B group,fermented Chinese herbs significantly improved the thymus index(P<0.05),ND antibody level of broilers at 3week(P<0.05).Overall,the immune function and antioxidant ability of broilers can be improved by the fermented Chinese herbs,which have better applicational effect than the herbs.
