摘要
在优化出海兰灰蛋鸡氨基酸模型的基础上,确立了日粮低蛋白水平15%、14%的试验;集成和优化了蛋鸡安全环保型日粮的配方和添加剂组合(包括复合酶、植酸酶、益生素、果寡糖、除臭灵等),开发出了产蛋鸡安全环保1%预混合饲料,使用该环保添加剂,在生产性能不降低的前提下,可使蛋鸡粪便氮、磷排出量分别降低;同时蛋壳质量和鸡蛋品质得到改善。
Based on the established model of the optimization of the amino acids pattern in Highland gray layers,the test of low-protein diet of 15%,14% were performed.The ration of integration,optimization and safe,and the supplement of additives（including the complex enzyme,phytase,probiotics,FOS,deodorant agent,and so on） were established in the layer.The 1% of pre-mixed feed was explored for safe and environmental protection.The supplement of additives with environmental protection was used to decrease dry matter,nitrogen and phosphorus excretion by 7.80%,26.47% and 39.06% in stool of layer,and the performance was not declined.In addition,the quality of the egg and eggshell was improved.
