Effects of Dendrobium officinale-Pinellia ternata Compound Additive on Growth Performance,Meat Quality,Immune Function and Antioxidant Function of Bian Chickens
试验旨在研究铁皮石斛-半夏复方添加剂对边鸡生长性能、肉品质、机体免疫和抗氧化功能的影响.选取60日龄边鸡(公鸡)240只,随机分为4个处理,每组6个重复,每个重复10羽.各组分别饲喂基础饲粮(对照组)和基础饲粮添加0.5%(试验Ⅰ组)、1.0%(试验Ⅱ组)、1.5%(试验Ⅲ组)铁皮石斛-半夏复方添加剂的试验饲粮.预试期5 d,正试期60 d.结果表明,与对照组相比,试验Ⅱ组边鸡的末重和平均日增重显著提高(P<0.05),料重比显著降低(P<0.05).铁皮石斛-半夏复方添加剂与边鸡末重、平均日增重和料重比呈二次曲线显著相关(P<0.05).试验Ⅱ组和试验Ⅲ组边鸡胸肌红度(a*)45 min和24 h显著提高(P<0.05),亮度(L*)24 h和滴水损失显著降低(P<0.05).试验Ⅱ组和试验Ⅲ组边鸡血清中免疫球蛋白A(IgA)、免疫球蛋白G(IgG)和白细胞介素-2(IL-2)含量显著提高(P<0.05),白细胞介素-1β(IL-1β)含量显著降低(P<0.05).试验Ⅱ组和试验Ⅲ组边鸡血清和肝脏中谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)活性和总抗氧化能力(T-AOC)显著提高(P<0.05),丙二醛(MDA)含量显著降低(P<0.05).综上所述,边鸡饲粮中添加铁皮石斛-半夏复方添加剂可以有效提高边鸡生长性能和肉品质,同时改善边鸡机体免疫功能和抗氧化能力.在本试验条件下,边鸡饲粮中铁皮石斛-半夏复方添加剂的最佳添加剂量为1%.
This experiment was conducted to investigate the effects of Dendrobium officinale-Pinellia ternata compound additive on growth performance,meat quality,immune function and antioxidant function of Bian chickens.A total of 240 60-day-old Bian chickens(males)were randomly allocated to 4 treatments with 6 replicates per treatment and 10 chickens per replicate.Chickens in each group were fed a basal diet(control group)or the basal diet supplemented with 0.5％(experimental group Ⅰ),1.0％(experimental groupⅡ)or 1.5％(experimental group Ⅲ)of Dendrobium officinale-Pinellia ternata compound additive,respectively.The pre-feeding period lasted for 5 days,and the experimental period lasted for 60 days.The results revealed that,compared with the control group,the final body weight and average daily gain of Bian chickens in group Ⅱ were significantly elevated(P<0.05),whereas the feed-to-gain ratio was significantly reduced(P<0.05).A notable quadratic curve correlation was observed between the Dendrobium officinale-Pinellia ternata compound additive and the final body weight,average daily gain and feed-to-gain ratio of Bian chickens(P<0.05).The meat color redness(a*)at 45 min and 24 h of Bian chickens in groups Ⅱ and Ⅲ were significantly enhanced(P<0.05),while the meat color lightness(L*)at 24 h and drip loss were significantly lowered(P<0.05).The serum levels of IgA,IgG and IL-2 of Bian chickens in groups Ⅱ and Ⅲ were significantly raised(P<0.05),and the level of IL-1β was significantly diminished(P<0.05).The serum and liver activities of GSH-Px,SOD and T-AOC of Bian chickens in groups Ⅱand Ⅲ were significantly improved(P<0.05),and the MDA level was significantly declined(P<0.05).In summary,dietary inclusion of Dendrobium officinale-Pinellia ternata compound additive can effectively enhance the growth performance and meat quality of Bian chickens,as well as boost the immune function and antioxidant capacity of Bian chickens.Under the conditions of this experiment,the optimal supplemental dosage of Dendrobium officinale-Pinellia ternata compound additive in the diet of Bian chickens is 1％.
