黄腐酸对蛋鸡生产性能的影响

Effects of Fulvic Acid on Production Performance of Laying Hens

将2 000只400日龄健康海塞克斯蛋鸡随机分成2组,对照组饲喂基础日粮,试验组在基础日粮中添加0.5 g/d黄腐酸产品,研究其对蛋鸡生产性能的影响。结果表明:与对照组相比,试验组平均蛋重极显著提高7.40%、平均产蛋率极显著提高5.20%、料蛋比极显著降低15.07%、死亡率降低90%、破蛋率降低42.5%、平均耗料量降低4.04%。

2 000 healthy Hysex Brown laying hens in age of 400 days were randomly assigned to a control and an experimental group. The hens of the control group were fed on a basal diet, while the hens of the experimental group were fed on the basal diet supplemented with 0.5 g/day fulvic acid, to study its effect on the laying performance. The results showed that in comparison with the control group, the average egg weight in the experimental group increased very significantly by 7.40%, its average egg -laying rate in- creased very significantly by 5.20% , its feed conversion ratio decreased very significantly by 15.07% , its death rate was reduced by 90%, its egg shell breaking rate was reduced by 42.5% and its average feed consumption was reduced by 4.04%.
