摘  要：
选用1日龄AA肉仔鸡共设雄性对照组(Ⅰ)、雄性芦荟粉组(Ⅱ)、雌性对照组(Ⅲ)和雌性芦荟粉组(Ⅳ)4个处理,Ⅰ、Ⅲ组饲喂基础日粮,Ⅱ、Ⅳ组均在基础日粮中添加600 mg.kg-1的芦荟粉。结果表明:雄性芦荟粉组比雄性对照组极显著降低了料肉比(P<0.01);21 d雄性芦荟粉组脾脏指数显著高于对照组(P<0.05);21 d雄性芦荟粉组新城疫血凝抑制效价显著高于对照组(P<0.05);42 d雄性芦荟粉组自然杀伤细胞杀伤活性极显著高于对照组(P<0.01)。说明日粮中添加芦荟粉可以提高肉仔鸡生产性能和免疫机能,且对雄性肉仔鸡生产性能和免疫机能影响效果优于雌性。

摘  要：
One hundred and twenty one-day-old male or female Arbor Acres broilers were randomly divided into two groups.Each group consisted of six replicates(10 birds per replicate).Group Ⅰwas the male control and Group Ⅲ was female control fed on the basal diet,Group II(male treatment) and Group Ⅳ(female treatment) fed on the basal diet supplemented with 600 mg·kg-1 aloe powder.The results showed that the feed conversion ratio of the male treatment group was significantly higher than that of the male control group(P<0.01).The ADG of both the male and female treatment groups had an upward trend compared with the control(P>0.05).Index of spleen of the male treatment group was significantly higher than that of the control on 21d(P<0.05).Indexes of thymus and bursa of the male and female treatment groups showed an increasing tendency compared with those of the controls(P<0.05) on 21d and 42d,respectively.The level of antibody against New Castle disease virus of the male treatment group was significantly higher than that of the control on 21d(P<0.05).The natural killer cell activity of the male treatment group was significantly higher than that of the control on 49d(P<0.01).Consequently,aloe powder appeared to be capable of improving the productivity and immunity of the broilers.And,the greater effect was found in male than in female broilers.
