| 摘 要： | 选择1日龄AA肉鸡(父系)与褐壳蛋鸡商品代(母系)的杂交肉鸡2400只,采用饲养试验,研究肉杂鸡在一个生产周期中对能量的适宜需要量。将肉杂鸡随机分成3个处理(中能组、高能组和低能组),三个处理除能量水平不同外,其余营养水平均一致。试验结果表明,在杂交肉鸡的整个饲养周期内,中能组的料重比显著高于高能组和低能组(P<0.05),本试验条件下肉杂鸡的最适能量水平前期(0～3周)和后期(4～6周)均为11.30MJ/Kg,这表明在不同的饲喂阶段选择合适的能量水平能够节约生产成本,提高肉杂鸡的生产性能。

| Abstract: | An experiment was conducted using 2400 one-day-old cross-bred chickens(paternal Arbor Acres broiler chickens×maternal commercial layer of brown-shell)to evaluate adequate energe requirement of hybridized chickens in one growth cycle.Three treatments include moderate-energy,high energy and low energy groups(no differences in any else nutrients levels).The results showed that the feed to gain ratio of cross-bred chickens in moderate-energy group were significantly higher than those in high energy and low energy groups(P<0.05)in the whole growthcycle.The adequate energy requirement of chickens in early growth and later growth stage were 11.30 MJ/kg,The results indicated that appropriate energy level can improve growth performance of cross-bred chickens and save in different growthstages. |
