【摘要】：本试验旨在研究酵母细胞壁替代恩拉霉素在黄羽肉鸡中的应用效果。采用单因素试验设计,选用1日龄新广黄羽肉鸡240羽,随机分为2个处理组,每个处理组12个重复,每个重复10只鸡,公母各半,分笼饲养。对照组饲喂基础日粮+恩拉霉素(250 g/t),试验组饲喂基础日粮+酵母细胞壁(1000 g/t)。试验期为6周,记录生长性能指标,并于21日龄采血测定血清球蛋白浓度、新城疫抗体水平。结果表明:酵母细胞壁试验组肉鸡生长性能参数较对照组无显著差异(P0.05),但是均有增强的趋势,其中42日龄出栏重提高1.3%,平均日增重提高1.3%,平均日采食量提高2.3%;同时,酵母细胞壁试验组肉鸡血清球蛋白浓度、新城疫抗体水平显著提高(P0.05)。综上,酵母细胞壁在饲料中替代恩拉霉素,对肉鸡生长性能无负面影响,同时可增强肉鸡免疫水平。
[Abstract]:The purpose of this experiment was to study the effect of yeast cell wall substitution for enramycin in yellow broilers. A single factor experimental design was used to select 240 1-day-old New-broad yellow feather broilers, which were randomly divided into 2 treatment groups, each treatment group with 12 replicates, each replica of 10 chickens, male and female half, raised in cages. The control group was fed the basal diet Enramycin 250 g / t and the experimental group was fed the basal diet yeast cell wall (1000 g / t). The test period was 6 weeks, the growth performance index was recorded, and the serum globulin concentration and Newcastle disease antibody level were measured at 21 days old. The results showed that there was no significant difference in growth performance parameters between yeast cell wall test group and control group, but there was a tendency to increase the growth performance of broiler chickens. Among them, the weight of 42-day-old broilers increased 1.3%, the average daily gain increased 1.3%, the average daily intake increased 2.3%, and the average daily intake increased 2.3%. In yeast cell wall test group, serum globulin concentration and Newcastle disease antibody level were significantly increased in broiler chickens. In conclusion, yeast cell wall can replace enramycin in the feed, which has no negative effect on the growth performance of broilers, and can enhance the immune level of broilers at the same time.
