中草药添加剂对林下饲养灵山麻鸡生产性能、屠宰性能和肉品质的影响

    Effects of Chinese Herbal Medicine Additives on the Production Performance, Slaughtering Performance and Meat Quality of Lingshan Ma Chickens Raised Under the Forest

    • 摘要: 为了研究中草药添加剂(金银花、白头翁、黄连、黄芩、黄柏)对林下肉鸡生长性能、屠宰性能和肉品质的影响。选取1 500只、体重相近、60日龄的健康灵山麻鸡分为对照组、试验Ⅰ组、试验Ⅱ组共3组,每组5次重复,每次重复100只鸡(公母各半)。对照组饲喂基础日粮;试验Ⅰ组(益生菌组)在基础日粮基础上增加益生菌复合剂兑水饲喂;试验Ⅱ组(中草药组)在基础日粮基础上增加中草药兑水饲喂;试验期120 d。结果表明:在基础日粮基础上增加中草药添加剂饲喂肉鸡,其增重效果不显著,但耗料量比及料重比分别比对照组低2.32%和1.79%;能够有效提高肉鸡机体的抗病能力,其死淘率最低(5.8%),出栏率最高(94.2%);同时还能够提高肉鸡屠宰性能和肉品质,中草药组的腹脂率、半净膛率、全净膛率等均高于对照组,显著高于益生菌组(P<0.05),胸肌和腿肌的肉色及切力比对照组显著提高;鸡肉中营养成分含量如蛋白质、脂肪含量、不饱和脂肪酸、饱和脂肪酸、油酸、亚油酸含量以及16种氨基酸含量均高于益生菌组和对照组。综合以上分析表明金银花、白头翁、黄连、黄芩、黄柏等中药组合作为林下养鸡的饲料添加剂候选抗生素替代品。

       

      Abstract: In order to explore the effects of Chinese herbal medicine additives (Lonicera japonica, Pulsatilla chiensis, Coptis chinensis, Scutellaria baicalensis and Phellodendri Chinensis Cortex) on the production performance, slaughter performance and meat quality of broiler chickens raised under the forest. 60-day-old health Lingshan Ma chicken was selected as the research object. 1 500 chickens with similar weight were randomly divided into three groups (the control group, experimental group Ⅰ, and experimental group Ⅱ) and each group was repeated five times with 100 chickens (half male and half female) each time. The control group was fed with basic ration; the experimental group Ⅰ(probiotics group) was fed with the probiotic complex additives mixed with water on the basis of basic ration; the experimental group Ⅱ(Chinese herbal medicine group) was fed with the Chinese herbal medicine mixed with water on the basis of basic ration. The experiment lasted for 120 days. The results showed that the effect of weight gain by adding Chinese herbal medicine additives to feed the broiler chickens on the basis of basic ration was not significant, but the ratio of feed consumption and feed conversion were respectively 2.32% and 1.79% lower than those of the control group. Adding the Chinese herbal medicine additives could not only effectively improve the disease resistance of broilers, with the death and culling rate being the lowest (5.8%) and the slaughtering rate being the highest (94.2%), but also improve the slaughter performance and meat quality of broilers. The abdominal fat percentage, the percentage of half-eviscerated yield and the percentage of eviscerated yield in the Chinese herbal medicine group were all higher than those in the control group, which were significantly higher than those in the probiotics group (P<0.05). The flesh color and shearing force of breast muscle and leg muscle were significantly improved compared with the control group. The contents of nutrients such as protein, fat, unsaturated fatty acid, fatty acid, oleic acid, linoleic acid and 16 amino acids in chicken were all higher than those in the probiotics group and the control group. The above analysis indicated that the combination of traditional Chinese medicine, such as Lonicera japonica, Pulsatilla chiensis, Coptis chinensis, Scutellaria baicalensis and Phellodendric hinensis cortex could be considered as the candidate substitute of antibiotics for the feed additives of chickens raised under the forest.
