摘 要:为研究获得高原地区海兰褐蛋鸡的最佳复合预混料配方,本试验选用海兰褐蛋鸡10 000羽,将其随机分为4组,每组2 500羽,试验组A、B、C分别饲喂低、中、高营养水平的自配预混料,对照组D饲喂商品料,并统计各组18~60周龄的产蛋量、产蛋率、平均蛋重及死淘率。结果表明,A组产蛋量、产蛋率、平均蛋重及成活率均最高;C组在产蛋量、平均蛋重和累计死亡率方面均优于D组和B组;B组仅产蛋率较高,累计死亡率排在第2。在海兰褐蛋鸡无抗养殖中,A组的复合预混料配方是最佳配方。In order to obtain the optimal compound premix formula for Hy-Line Brown hens in plateau area,10000 Hy-Line Brown hens were randomly divided into 4 groups with 2500 hens in each group.Experimental groups A,B and C were fed low,medium and high nutrient level premix,respectively,while control group D was fed commercial feed.The egg production,laying rate,average egg weight and death rate of all groups aged 18 to 60 weeks were analyzed.The results showed that group A had the highest egg production,laying rate,average egg weight and survival rate.Group C was superior to group D and group B in egg production,average egg weight and cumulative mortality.Group B only had higher egg production rate,and the cumulative death rate ranked second.The compound premix formula of group A was the best formula in the non-antibiotic culture of Hy-Line Brown hens.
