摘要
试验选取40、70、150和230日龄健康、体重接近的武定鸡公、母鸡各12只,比较不同性别、日龄和屠体部位肌肉肌苷酸(IMP)及IMP前体物、IMP降解物和ATP总代谢物含量,探讨肌苷酸的沉积规律。结果表明:日龄对武定鸡肌肉IMP及其相关核苷酸含量影响显著(P<0.05),随着日龄的增加IMP含量呈先增后降的趋势,150日龄时IMP含量显著高于其他日龄(P<0.05);性别及屠体部位对武定鸡肌肉IMP含量有显著影响(P<0.05),但对其相关核苷酸含量影响不明显,150日龄时武定鸡母鸡肌肉IMP含量显著高于公鸡(P<0.05),40和230日龄时其胸部肌肉的IMP含量显著高于腿部肌肉(P<0.05)。
The experiments through compared the contents of Wuding chicken＆#39;s muscle IMP and its related nucleotides （ATP,ADP,AMP,Hx,HxR） in different gender, age and carcass parts to explore the deposition rule of IMP. The results showed that the age having significant effects to the contents of IMP and its related nucleotides （P〈0.05）, with the age increasing, the contents of IMP showed a tendency that first increased and then dropped, and the contents of IMP were significant higher in 150-day-age than other ages （P〈0.05）. The gender and carcass parts also having significant effects to the contents of IMP （P〈0.05）, but no significant effects to the contents of IMP related nucleotides;The contents of IMP in the hen muscles in 150-day-age were significant higher than the cock （P〈0.05）, and the IMP contents of chest muscles in 40-day-age and 230-day-age were significant higher than the leg muscles（P〈0.05）.
