摘 要:选择140日龄健康的伊苏褐商品蛋鸡7984羽,随机平分成试验和对照两组,试验组在蛋鸡全价料中前期(147-210日龄)添加400mg/kg和后期(280-420日龄)添加300mg/kg的801生物活性添加剂。结果表明:全期试验组比对照组蛋鸡死亡率下降16.86%(P<0.01),产蛋量增加1.96%,料蛋比下降0.78%,投入产出比为1:4.18,平均每羽获利1.20元,尤其在热应激时效益更为明显,投入产出比为1:6.07.Isabrown Commereial Layers of 20 week-old were randomly divided into two groups for different diet treatment. BA 801 was added to the diet for the experimental group(3 992 hens)at calculated levels of 400 ppm during 21 week old to 30 week old, and 300 ppm during 40 week old to 60 week old.The results showed that the experimental layers during 21th week to 60th week displayed the mortality being 16.81% lower(P<0.01),egg weight 1.96% higher and feed consumption 0. 78% lower,thus the input and output ratio reaching 1:4.18,and the profit per hen going up to 1.20 Yuan (RMB).Perticularly during the hot time(48th week to 55th week)the income was greatly increased,the input and output ratio came to as high as 1:6.07.
