维生素C和中草药添加剂对夏季蛋鸡产蛋性能的影响

本试验选用海兰褐父母代蛋用种母鸡，观测在夏季饲粮中，使用不同水平的VC和中草药添加剂，对其产蛋性能的影响。结果表明：在饲粮中添加0．04％V．C、0．02％V．c＋1％中草药添加剂．及1％中草药添加剂组的产蛋率比对照组分别提高11．78％、15．88％、11．04％，差异极显著（P＜0．01）；在饲粮中添加0．5％中草药、0．02％V．C、0．02％V．c＋0．5％中草药添加剂、0．04％V．c＋1％中草药添加剂组的产蛋率显著高于对照组（P＜0．05）；饲料转化率，试验组分别比对照组提高15．23％－20．20％。据验证：在夏季的蛋鸡饲粮中添加0．02％V．c和1％中草药添加剂，其生产性能为最好。

EFFCT OF Vit.-C AND CHINESE HERBS ON EGG LAYING PERFORMANCE DURING THE SUMMER

450 58-week Hyline were randomly divided into 9groups and wefe fed With different level of Vit. C and Chinese herbs. The egg laying ration has been showed that; the group of diet with 0.04% Vit. C. 0. 02%, Vit. C+1. 00% Chinese herbs,1. 00% Chinese herbs has increased by 11. 78%. 15. 88% and 11.04% respectively (P<0.01). The group of dlet with 0. 5% Chinese herbs. 0.04% Vit. C+1.00% Chinese herbs also increased (P<0.05). The efficiency of feed utilization in experimental group has more 15. 23% to 20. 20% than that of control group. In this report; the best diet of the egg-laying poultry during the summer is the diet with addltional 0.02% Vit. C+1.00% Chinese lierbs.
