摘要：目的研究中草药添加剂对鸡产蛋率、产蛋性能及蛋鸡本身的影响，从而为运用鸡冠花籽粒、枣粉配伍组成的中草药添加剂合理进行蛋鸡养殖、降低养鸡饲料成本提供可靠的实验室依据。方法日粮中添加不同比例的中草药饲料添加剂，观察并记录分析蛋鸡产蛋性能（产蛋率、产蛋数、蛋总量、耗料总量、料蛋比）及鸡蛋品质（蛋壳厚度、蛋形指数、蛋白高度、蛋黄比色等）。结果由鸡冠花籽粒、枣粉按一定比例配伍组成的中草药饲料添加剂提高了蛋鸡产蛋率及产蛋性能，对鸡蛋品质无影响。并且日粮中添加4%的添加剂比添加2%更有效。结论由鸡冠花籽粒、枣粉按一定比例配伍组成的中草药饲料添加剂能够有效提高蛋鸡产蛋率及产蛋性能，对鸡蛋品质无影响。

Abstract:Objective To study effect of Herbal feed additive on Chicken egg production,laying performance and egg itself.Thus the use of cockscomb seeds, jujube powder reasonable compatibility of Chinese herbal medicine consisting of the laying hens to reduce the cost of chicken feed which could provide a reliable basis for the laboratory.Methods Diets supplemented with different proportions of herbal feed additives, observe and record the performance of laying hens (laying rate, egg number, egg volume, total feed consumption, feed egg ratio) and egg quality (shell thickness , egg shape index, a high protein, egg yolk than the color, etc.). Effects The herbal feed additives of cockscomb seeds and jujube powder formed by a certain percentage improved laying rate and egg production performance and had no effect on egg quality. The Dietary additives of 4% were more effective than 2%. Conclusions The herbal feed additives of cockscomb seeds and jujube powder formed by a certain percentage could improve the performance of laying hens and egg laying rate and no effect on egg quality.
