| 摘 要： | 将384只21日龄试验鸡随机分为Ⅰ-Ⅳ组,每组3个重复,每个重复32只.Ⅳ组为空白对照组,饲喂基础日粮;Ⅰ-Ⅲ组为试验组,分别在基础日粮中添加2、4 mg.kg-1中药添加剂和36 mg.kg-1饲用抗生素(含6 mg.kg-1硫酸粘杆菌素和30 mg.kg-1杆菌肽锌),研究以黄芪、黄芩、茯苓、白术为主的复方中药添加剂对优质鸡生产和屠宰性能的影响.结果表明:(1)中药Ⅰ、Ⅱ组试验鸡130日龄体重分别比对照组和抗生素组提高10.60%、11.92%(P<0.01)和0.81%、2.01%(P>0.05);中药Ⅰ、Ⅱ组和抗生素组试验鸡全程料肉比与对照组比较分别降低11.32%、12.45%、11.88%,差异均极显著(P<0.01).(2)中药Ⅰ组公鸡半净膛率比抗生素组和对照组分别提高7.64%(P<0.05)和7.54%(P<0.05);中药Ⅰ组公鸡全净膛率比抗生素组和对照组分别提高8.30%(P<0.05)和9.03%(P<0.05).(3)中药Ⅰ、Ⅱ组公鸡胸肌的剪切力比对照组分别提高58.23%(P<0.05)和98.26%(P<0.05),与抗生素组比较差异均不显著(P>0.05);中药Ⅰ、Ⅱ组母鸡胸肌的剪切力比抗生素组和对照组分别提高67.12%、37.54%和71.60%、41.23%,差异均显著(P<0.05).可见,中药添加剂能提高优质鸡的生产和屠宰性能,改善鸡肉品质.

| Abstract: | Effects of Chinese herbal medicine additives which were made of Astragalus sp.,Poria cocos,Wolfiporia cocos and Atractylodes macrocephala on the growth performance and meat quality of local chickens were investigated.384 21-day-old local chickens were randomly divided into four groups,each group had three replications(32 birds per replicate).Treatment groups(group Ⅰ-Ⅲ) were fed with the basal diet supplemented with 2,4 mg·kg-1 of Chinese herbal medicine additive and 36 mg·kg-1 of mixture of nutritional antibiotics(6 mg·kg-1 of colistin sulfate+30 mg·kg-1 of zinc bacitracin),respectively.The control group(group Ⅳ) was fed with basal diet only.The results showed as follows:(1) the body weight(130 days old) in group Ⅰ and group Ⅱ increased by 10.60%,11.92%(P<0.01) than the control group,by 0.81%,2.01%(P>0.05) than group Ⅲ respectively;during the entire period,the feed conversion ratio of group Ⅰ, group Ⅱ and group Ⅲ were 11.32%,12.45%,11.88% respectively,significantly higher than that of control group(P<0.01).(2) The percentage of half-eviscerated yield in group Ⅰ for male increased by 7.64%(P<0.05) and 7.54%(P<0.05) than group Ⅲ and the control group;the percentage of eviscerated yield in group Ⅰ for male increased by 8.30%(P<0.05),which was 9.03%(P<0.05) and 5.24%(P>0.05) higher than group Ⅲ and the control group,respectively.(3) The shearing force in group Ⅰ and group Ⅱ for male increased by 58.23%,98.26%(P<0.05) than the control group;the shearing force in group Ⅰ and group Ⅱ for female increased by 67.12%,37.54% than the group Ⅲ,by 71.60%,41.23% than the control group respectively.It was indicated that Chinese herbal medicine additives could obviously improve the local chickens′ growth performance,slaughter performance and meat quality. |
