摘　　要：本研究旨在探讨酵母培养物对肉种鸡产蛋后期生产性能的影响。试验选择42周龄体重相近、健康的艾拔益加(AA+)和罗斯(Ross)肉种鸡群共36400只,每个种群都随机分为对照组和试验组,共4个处理组。试验分为预饲期1周,试验期16周。在饲养过程中,对照组饲喂玉米豆粕基础饲粮;试验组饲喂添加0.2%酵母培养物的基础饲粮。研究结果显示,饲粮中添加酵母培养物可降低肉种鸡产蛋后期的死淘率,提高种蛋品质,改善肉种鸡产蛋后期所能提供的合格蛋数。This study was done to investigate the effects of yeast culture on the reproductive performance of broiler breeders. A total of 36,400 healthy broiler breeders of AA and Ross were used in this study, and each population of AA or Ross was randomly divided into control groups and test groups, in total of 4 treatments. The study was performed as a pre-feeding period with 1 wk, and a trial period with 16 wks. During the trail, the birds in control groups were fed with corn-soybean basal diet;the birds in treatment groups were fed the basal diet + 0.2% yeast culture. The results showed that adding yeast culture into the basal diet significantly decreased the mortality and elimination rate of the broiler breeders in late laying period, improved the quality of the breeding eggs, therefore, increased the qualified breeding eggs provided by the broiler breeders at the later stage of laying.
