摘  要：
对12周龄兴义矮脚鸡和矮脚黄鸡的屠宰性能、常规肌肉品质及肌肉脂肪酸、氨基酸含量进行比较。结果表明:12周龄时,兴义矮脚鸡活重极显著高于矮脚黄鸡(P<0.01),而腿肌率和屠宰率显著低于矮脚黄鸡(P<0.05);肌肉失水率和胸肌纤维直径极显著低于矮脚黄鸡(P<0.01);兴义矮脚鸡除色氨酸外,其余7种必需氨基酸均高于矮脚黄鸡;胸肌亚油酸含量兴义矮脚鸡为17.66%,矮脚黄鸡为15.29%。

摘  要：
The slaughter character and muscle quality of 12-week-old Xingyi dwarf and yellow dwarf chicken was compared in this study.The results showed as follows:Xingyi dwarf's body weight was significantly higher than yellow dwarf chicken(P<0.01) ,but the percentage of its leg muscle and slaughter percentage were all lower than yellow dwarf chicken(P<0.05) at 12 weeks age.The dehydration rate and diameter of breast muscle cellulose of Xingyi dwarf were all significantly lower than those of yellow dwarf chickens(P<0.01) .Except tryptophan content of breast muscle of Xingyi dwarf chicken was lower than that of yellow dwarf chickens,the other 7 kinds of essential amino acid were all higher than those in the latter.The linoleic acid content of breast muscle of Xingyi dwarf chicken was 17.66%,for yellow dwarf chickens,which is 15.29%.
