摘要
300只海兰白商品代60周龄的产蛋鸡，随机分为3组。试验I组、Ⅱ组分别在基础日粮中添加0．5％、1％中药添加剂，第Ⅲ组为对照组。观察各组每天的产蛋率、日产蛋量等生产性能指标，并定期测定蛋品质指标。结果：试验Ⅰ组、Ⅱ组比对照组的料蛋比、产蛋率、哈夫单位及蛋黄颜色均显著提高，平均蛋重、蛋形指数及蛋壳厚度均比对照组高，但差异不显著，其他指标与对照组差异不显著。结论：在蛋鸡日粮中添加0．5％～1％的中药散剂，可显著提高产蛋率和蛋品质。
300 60-week-old layers were divided into 3 groups randomly, in experimental groupⅠ andⅡ , 0.5% and 1% Chinese herb additive were added into diet respectively, group Ⅲ was control group. The egg quality and the performance indexs inclding laying rate and egg production were studied. The results indicated that, the laying rate, the feed conversion rate, haugh unit and yolk color of group Ⅰ and group Ⅱ were significantly higher than those of the control group, and no significant difference in other indexs was observed among the groups. In conclusion, Chinese herb additive at the dosage of 0.5%-1% added into the layers diet could improve the performance and the egg quality of layers obviously.
