초록
본 실험은 산란노계에서 강제환우 후에 단백질과 에너지수준이 다른 사료를 급여시에 생산성에 미치는 영향을 구명하고자 실행하였다. 76주령 이사브라운 노계를 강제환우후에 2수준의 단백질(15,17%)과 3수준의 대사에너지(2,750, 2,800, 2,850kca1/kg)를 2
This experiment was conducted to investigate the influence of different dietary ME and CP on post-molt performance of spent laying hens. Four hundred and thirty two, ISA brown after molt induction were fed 6 experimental diets containing 3 ME(2,750, 2,800, 2,850 kcal/kg) and 2 CP(15, 17%) levels in factorial design. The influence of ME and CP were measured on body weight, egg production, egg weight and feed intake throughout 24 weeks of production. Egg mass and FCR were calculated for the entire experimental period body weight remained less in hens receiving 2,800 kcal/kg. ME and showed the highest egg Production coupled with 15% CP. Feed intake decreased with the increasing level of ME and CP. As the results of this experiment, 2,800 kcal/kg ME can be used to maintain the low body weight and to obtain higher egg production with 15% CP in induced molting hens.
