The effect of feeder space on body weight uniformity of adolescent broiler breeder females during a feed restriction program was evaluated. From 2 to 20 wk of age, broiler breeder pullets were fed a starter/developer diet containing 16.0% protein and 2,944 kcal ME/kg feed. Feed allocations, predicated on mean pen body weight, were fed on an every other day basis. Feeder space was 45 or 90% of that recommended for use with a feed restriction program. The mortality, feed efficiency and body weight uniformity data all support the hypothesis that it is not necessary to provide enough feeder space to enable all birds to eat simultaneously. Broiler breeder pullets provided only 45% of the recommended feeder space responded as well as, or better than, those given 90% of the recommended feeder space.
评估了在限饲程序期间，饲养空间对青春期肉种鸡母雏体重均匀度的影响。从2周龄到20周龄，给肉种鸡雏鸡饲喂含16.0%蛋白质和2944千卡代谢能/千克饲料的育雏/育成期日粮。根据栏舍平均体重进行的饲料分配，每隔一天饲喂一次。饲养空间为限饲程序推荐使用量的45%或90%。死亡率、饲料效率和体重均匀度数据均支持这样的假设，即没有必要提供足够的饲养空间以使所有鸡只能够同时采食。仅提供推荐饲养空间45%的肉种鸡雏鸡的反应与那些给予推荐饲养空间90%的雏鸡一样好，甚至更好。
