摘要
2880只385日龄的伊莎褐商品蛋鸡分为两组,每组1440只.试验组日粮是在基础日粮中添加0,5%芽孢杆菌添加剂.对照组喂基础日粮.在3周试验期间,试验组产蛋率提高的幅度(13.09%)高于对照组(8.42%).试验组与对照组相比,每产1kg蛋少耗饲料0.37kg,提高饲料效率9.69%.使用芽孢杆菌制剂后每枚蛋重平均增加0.26g.
2880 385-day-old ISA brown commercial laying hens were assigned to one of two groups with 1440 hens each. Hens in the experimental group were fed the basal diet added with 0. 5% spore bacilli. The basal diet was fed to hens in the control group. During the 3-week experimental period, a bigger increase in egg production was observed in the experimental group (13. 09%)than in the control group(8. 42%). A 0. 37-kg decrease in feed consumption per kg of eggs produced was observed in the experimental group compared to the control group. Feed efficiency improved 9. 69%. Use of spore bacilli resulted in an increase of 0. 26g in average weight per egg.
