摘要
将1200只罗曼商品代产蛋鸡随机分成二组(试验组和对照组)来确定ZA复合添加剂(自制)对产蛋鸡产蛋性能的影响及饲喂效果。试验期间饲喂ZA复合添加剂的试验组产蛋率为72％,而对照组产蛋率为63.2％,试验组较对照组产蛋率高出7.4％,经t检验,二组间产蛋率差异呈现极显著(P<0.01);经济效益分析,试验组比对照组多创利润400多元,经济效益相当可观。
One thousahd and two hundred Romen laying hens were randomly allocated to a trial group and a control group to determine the effects of ZA complex addi-cive on egg laying pergormance and egg-feed ratio The laying rate was 72% in the trial group geeding ZA complex additive in-test; while that of the control group was 63.2% The laying rate of trial group increased 7.4% than the control group By T-test,the laying rates differed significantly between the two groups (p<0.01). The economic efficiency was also significant by analysing. The profits of the trial group increased 400 yuan than that of the control group.
