摘要
采用颗粒饲料和粉状饲料对４００ 只 ＡＡ肉鸡进行饲养试验，试验分为两组，每组各２００只，设一个重复。试验结果表明：饲喂颗粒饲料的平均日增重为 ５４．６５ ｇ，比粉料组的平均日增重４７．６７ ｇ高出 １４．６％。对各周龄雏鸡活重的比较表明，颗粒饲料组极显著优于粉料组（Ｐ <０ ．０１）。但两组的死亡率无显著差异。随着日龄的增加，料重比呈现增大的趋势。粉料组的总料重比为１．８７ 较颗粒饲料组的１．７６高出６．２５％，颗粒料较粉料饲喂经济效益为好。
AA broilers were used in this experiment. All broilers bad been divided into two groups. One group was feed with grain feedstuff, while the other one used powder feedstuff The results showed that the group feed grain feedstuff had a daily increased weight 54. 65 g, which was higher 14. 6% than the powder group. The each weekend weight in the grain group was markedly better than that of powder(P<0.01). There was no difference on death rate between two groups. The feedstuff body - weight ratio was increased with age both in two groups, the general feed weight ratio of the powder group was 6. 25 percent higher than that of the grain group. On economical efficiency the grain group better than the powder.
