摘　　要：[目的]为京海黄鸡的肉品质评价方法和评价标准的制定提供参考依据。[方法]以京海黄鸡为试验素材,研究不同日粮蛋白和能量水平对京海黄鸡肌肉中IMP和IMF沉积规律的影响。[结果]试验4组公鸡胸肌中IMP含量极显著高于试验1组(P<0.01),在腿肌中IMP含量差异不显著(P>0.05);母鸡肌肉中IMP含量在同一部位、不同组别间差异均不显著(P>0.05),公、母混合后IMP含量随着蛋能水平的增加呈上升趋势,但在相同部位、不同组别间差异均不显著(P>0.05)。试验4组公鸡腿肌IMF含量显著高于试验1组(P<0.05),极显著低于试验2组(P<0.01),在胸肌中的IMF含量差异不显著(P>0.05);母鸡肌肉中IMP含量在同一部位、不同组别间差异均不显著(P>0.05),公、母混合后,试验2组腿肌IMF含量显著高于试验1组(P<0.05),极显著高于试验4组(P<0.01)。[结论]不同蛋能水平与京海黄鸡肌肉中IMP的沉积呈正相关,与IMF沉积呈负相关。[Objective] The research aimed to provide reference basis for making the evaluation methods and standards of meat quality of Jinghai Yellow Chicken. [ Method] Taking Jinghai Yellow Chicken as test materials, the effects of different protein and energy levels of diet on the deposition laws of inosine monophosphate （IMP） and intramuscular fat （IMF） in the muscles of Jinghai yellow Chicken were studied. [ Result] IMP content in the breast muscle of cocks in test group 4 was significantly higher than that in test group 1 （ P 〈 0.01 ）, but IMP con- tent in leg muscle had no significant difference （P 〉 0.05 ）. There was no significant difference of IMP content in the same tissue among differ- ent groups in the muscles of hen. After mixing hens and cocks, IMP content in showed the increasing trend with the increase of protein and en- ergy levels, but there was no significant difference in the same tissue among different groups （ P 〉 O. 05 ）. IMF content in the leg muscle of cocks in test group 4 was significantly higher than that in test group 1 （P 〈0.05）and significantly lower than that in test group 2（P 〈0.01 ）. But there was no significant difference in the leg muscle （P 〉 0.05）. There was no significant difference of IMP content in the same tissue a- mong different groups in the muscles of hens （P 〉 0.05 ）. After mixing hens and cocks, IMF content in the leg muscles in test group 2 was significantly higher than that in test group 1 （ P 〈 0.05 ） and significantly higher than that in test group 4 （ P 〈 0.01 ）. [ Conclusion] Different protein and energy levels showed positive correlations with the deposition of IMP in the muscles of Jinghai Yellow Chicken and negative correla- tion with IMF deposition.
