| 摘 要： | 480羽1日龄AA肉鸡,随机分为4组,每组120羽,设6个重复,其中空白对照组饲喂玉米-豆粕型基础日粮,抗生素组基础日粮添加50mg/kg金霉素,试验Ⅰ组(低聚壳聚糖剂量组)和试验Ⅱ组(黄芪多糖高剂量组)分别添加20mg/kg和40mg/kg低聚壳聚糖,试验期42d,研究低聚壳聚糖对肉仔鸡生长性能及免疫器官发育的影响。结果显示,试验Ⅰ、Ⅱ组肉仔鸡的平均体重、日增重、免疫器官重量及其指数均不同程度高于同期空白对照组和抗生素组,其中平均体重与日增重多差异显著(P<0.05),部分免疫器官重量与指数有统计学意义(P<0.05);平均料重比均较明显地低于同日龄空白对照组和抗生素组。试验结果表明,基础日粮添加20、40mg/kg低聚壳聚糖对肉鸡的生长性能及免疫器官发育具有较明显的促进作用,可提高肉鸡的平均日增重和饲料转化率,增强机体的免疫功能。 |

| Abstract: | To study the effects of oligo-chitosan on growth performance and development of immune organs of broilers,a total of 480 one-day-old healthy Arbor Acre(AA) broilers were randomly divided into four groups,and each group was replicated six times with 20 broilers.The control group was fed with the corn-soybean basal diet;the antibiotics group was fed with basal diet added 50 g/t Aureomycin;and the experimental group I(oligo-chitosan low dose group) and group Ⅱ(Oligo-Chitosan high doses group) were fed with the basal diet supplemented with 20 mg/kg,40mg/kg oligo-chitosan respectively for 42 days.Compared with the control group and the antibiotics group of the same age,the average daily gain and body weight of broilers in the experiment group I and Ⅱ increased more significantly(P<0.05),the weight and organ indexes of immune organs increased and there were significant differences in part of these data(P<0.05),but the feed to gain ratio of the experiment group decreased obviously.The results showed that the basal diet supplemented with 20 mg/kg,40mg/kg oligo-chitosan could obviously promote the growth performance of broilers and the development of immune organs,improve the average daily gain and feed conversion ratio of broilers,and enhance the immune function of organism. |
