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。
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（P0.05）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.
