微生态制剂HGB在蛋鸡养殖中的应用

目的]探讨微生态制剂HGB在蛋鸡养殖中的应用效果。方法]选取400只健康的80日龄商品代罗曼褐蛋鸡,随机分为试验组与对照组,饲养条件相同,均饲喂基础日粮,试验组添加微生态制剂HGB。结果]使用微生态制剂HGB有助于增加蛋鸡体重、提高蛋鸡对饲料的利用率,并能改善蛋鸡的生产性能,也可改善试验蛋鸡的饲养环境。与对照组相比较,在试验期间的第135~165天,试验组的料蛋比低0.20,产蛋率高8%,产蛋总数增加496枚。经方差分析表明2组结果差异极显著(P<0.01)。结论]使用微生态制剂HGB可增加蛋鸡体重,提高蛋鸡对饲料的利用率,改善蛋鸡的生产性能,提高蛋鸡产蛋量,还可改善蛋鸡的饲养环境。

Application of HGB Microbial Ecological Agents in Layer Breeding

Objective] The aim was to discuss the application effect of HGB microbial ecological agents in layer breeding.Method] 400 healthy commercial stock Roman Brown layers,80 day old,were selected and divided into experimental group and CK group randomly.The raising conditions were same with all feeding basal diet.The layers in the experimental group were added by the microbial ecological agent.Result] Using HGB microbial ecological agents was helpful to increase the weight of layers,advance the utilization rate of layers to feedstuff,improve the production performance of layers and improve the feeding environment of experimental layers.Compared with the CK group,the ratio of feed to egg in experimental group was decreased by 0.02,the laying rate was increased by 8% and the total egg number was increased by 496 in the 135-165 d of experiment.The variance analysis showed that the result of the 2 groups had very significant difference(P<0.01).Conclusion] Using HGB microbial ecological agents could increase the weight of layers,advance the utilization rate of layers to feedstuff,improve the production performance of layers,increase the egg production of layers and improve the feeding environment.
