摘要
试验选用450日龄"京红1号"商品代产蛋鸡600只,随机分成4组,每组5个重复,每个重复30只鸡。研究添加不同水平的光合细菌菌液对蛋鸡产蛋性能的影响。试验结果表明:饮水中添加1.5%光合菌液(含菌量为30亿/mL)能改善蛋鸡的生产性能,明显提高其产蛋率和日产蛋量,促进饲料的消化与吸收,提高抗病能力。
600 450-day-old ＂Beijing red 1＂ laying hens were randomized into 4 groups with each group for 5 repeat and every repeat for 30 laying hens. The results suggested that the production performance , feed digestibility and disease resistance of layng hens in drinking water supplemented with 1.5% photosynthetic bacteria liquid （photosynthetic bacteria, 3 billion/ml） were significantly improved.
