| 摘 要： | 选择45周龄的两栋共6000只海兰褐父母代,其中一栋设为试验组,另一栋设为对照组,每栋随机分为3个重复,每个重复1000只鸡.试验组在基础日粮中添加1.5 g/kg复合微生态制剂,添加时间为23 d,对照组饲喂基础日粮.结果表明:日粮中添加1.5 g/kg复合微生态制荆可显著提高蛋种鸡的产蛋率(P＜0.05),平均蛋重(P＜0.05),受精率和受精蛋孵化率(P＜0.01),极显著降低料蛋比,破蛋率和淘汰率(P＜0.01);可显著提高日粮粗蛋白、钙和磷的表观营养物质吸收率(P＜0.05),从而提高蛋白哈氏单位和蛋壳相对重(P＜0.05).

| Abstract: | Effects of compound microbial ecological agents on production performance,egg quality and nutrient digestibility of layer breeders were studied in this paper. Two flocks of 6 000 45-week-age Hy-Line brown parents were randomly divided into two groups,each group was assigned 3 replications and 1 000 layers per replication. One flock was control group feeding basal diets and the other were fed basal diets with 1.5 g/kg the compound microbial ecological agents. The study lasted for 23 days. The results showed ... |
