摘要
对ＡＡ肉用种鸡在育雏育成期进行每日限饲和分段限饲对比试验。结果：成活率差异不显著（Ｐ＞０．０５），开产时间均为２４周龄，但分段限饲耗料较少，均匀度优于每日限饲，高峰产蛋率（周）：分段限饲８４．３％，每日限饲６７．６％，差异极显著（Ｐ＜０．０１）。
Results from comparations between daily feed restriction and interval feed restric-tion for AA parent stock at rearing chick and growing period showed that there was no signifi-cant difference(P>0.05)on liveability and maturity(at the age of 24 weeks) between the twomethods,but,compared with daily feed restriction, interval feed restriction birds consumed lessfeed,gave a higher uniformity higher production and peak production rate(P<0. 01).
