摘要
试验采用单因子设计方案,选取339日龄的健康海兰褐蛋鸡360只,随机分成对照组和试验组,每组设3个重复,每个重复60只鸡。对照组饲喂基础日粮,饮用普通水;试验组在基础日粮和饮水中添加泓缘403菌,试验期8周。试验结果表明:试验组较对照组料蛋比显著降低(<0.05),每只鸡平均多盈利0.17元,经济效益得到了提高。
Signal factor design was employed in the experiment. A cohort of 360 healthy Hailan Brown Layers of 339 days were chosen randomly and divided into control group and experimental group.In each group there were 3 repeats, each of which with 60 layers. During the 8 weeks test period, control group were fed basal diet, while the experimental group were fed basal diet added with Hongyuan 403 Bacteria. The results turned out that in experimental group, addition of Hongyuan 403 Bacteria significantly reduced feed to egg ratio compared with control group （P 〈 0.05）and every layer profited more 0.17 yuan,the economic efficiency was improved.
