摘要
研究加味强壮散对白羽肉鸡的抗氧化功能和免疫球蛋白及脏器组织形态结构的影响,为加味强壮散用于白羽肉鸡健康养殖提供依据。选取88只健康、体重相近的1日龄白羽肉鸡,雌雄各半,随机分成4组,包括1个空白对照组(饲喂基础饲粮)和3个试验组(分别在基础饲粮中添加0.2%、0.4%、0.8%的加味强壮散),连续饲养42 d。与对照组相比,饲粮添加0.8%加味强壮散能显著提高血清总抗氧化能力、谷胱甘肽过氧化物酶活力(P<0.05),显著降低血清中丙二醛含量(P<0.05),能显著提高血清免疫球蛋白IgA和IgM的含量(P<0.05);组织形态学观察发现加味强壮散可促进免疫器官发育。在饲粮中添加不同比例的加味强壮散可提高白羽肉鸡的抗氧化功能,增加免疫球蛋白含量,促进免疫器官发育,其中以0.8%的添加量效果最佳。
To study the effects of Jiawei Qiangzhuang powder on antioxidant function,immunoglobulin and morphological structure of viscera in white-feathered broilers,providing an experimental basis for Jiawei Qiangzhuang powder to be used in the healthy breeding of white feather broilers,eighty-eight healthy 1-day-old white feather broilers of similar weight(half male and half female)were randomly divided into four groups,including one control group(Group C)(fed with basic diet)and three experimental groups(added with 0.2%,0.4%and 0.8%Jiawei Qiangzhuang powder in basic diet respectively),low dose group(Group L),medium dose group(Group M)and high dose group(Group H)respectively,and were feed continuously for 42 days.Compared with Group C,Group H significantly improved total antioxidant capacity(T-AOC)and the glutathione peroxidase(GSH-Px)activity(P<0.05),and significantly reduced the content of malondialdehyde(MDA)in the serum(P<0.05),and significantly increased the contents of IgA and IgM in the serum(P<0.05).Viscera histomorphology observation found Jiawei Qiangzhuang powder could promote the development of immune organs.Adding different proportions of Jiawei Qiangzhuang powder to the diet could improve antioxidant function of white feather broilers,and increase the contents of immunoglobulins,promote the development of immune organs,with 0.8%being the best addition.
