肉用仔鸡早期限食饲养试验

The Experiment of Feeding Limited Forage to small chick

试验对7日龄肉用仔鸡进行了10d限食饲养,限食量分别为对照组的70%、60%、55%和50%,到56日龄时,除限食量为50%组日增重较低外,其它各试验组分别比对照组提高8.5%(P〈0.05)、7.5%(P<0.05)和6.79%,饲料报酬和心脏病发生率以限食量为60%和55%的试验组较好。试验就肉用仔鸡实施限制性饲养进行初探,旨在提供一个降低养鸡成本的途径。

The experiment lasted ten days.I fed limited forage to seven-day-old chicks,The number of forage is orderly 70%,60%,55%and50%.After 56 days except that the 50%-group put on weight comparatively slowly every day,the other groups increased orderly 8.57% （P 〈0.05）,7.5% （P 〈0.05）and6.99%.The 60% -group and the 55%-group,their cost of forage is less,and the heart disease rate is lower.The experiment is a first attempt on feeding limited forage to small chicks,in order to supply a way that can decrease the cost of raising chicks.
