【摘要】 研究复合酶制剂对蛋鸡产蛋后期生产性能、鸡蛋品质及血液生化指标的影响。结果表明:添加复合酶制剂对产蛋率和料蛋比有一定的改善作用,但对蛋重和鸡蛋品质无显著影响;复合酶制剂3组总蛋白、球蛋白、血磷含量均显著增加(P<0.05),各试验组白蛋白和甘油三酯含量均有不同程度的提高,而尿素含量均有不同程度的降低。更多还原

【Abstract】 The effect of complex enzyme preparations on production performance,egg quality and blood biochemical indexes of egg-layers in later laying stage was studied.The results showed that adding complex enzyme preparations improved the egg laying rate and feed-egg ratio in a certain extent,but influenced the egg weight and quality not significantly.The contents of total protein,globulin and blood phosphor in three groups of complex enzyme preparations were all increased significantly(P<0.05),the contents of albumen and triglyceride in each test group were all increased in different degrees,while the contents of urea were all decreased in different degrees.更多还原
