摘要: 试验选取70日龄大恒优质肉鸡4个纯系与2个杂交品系共120只(各品系公、母各10只)为试验材料,对其胸肌肌苷酸和鲜味氨基酸的含量进行了研究。结果表明:①肌苷酸含量在品系间存在差异,其中S08品系的含量最高;除了S03与S08、S02与 S06、S02与 S08×S01、S06与 S08×S01之间差异不显著,其他各品系两两间均达到差异显著水平(P<0.05);②谷氨酸、甘氨酸、天冬氨酸、丙氨酸和精氨酸含量在各品系间存在差异,其中杂交品系S08×S01的5种鲜味氨基酸含量均最高;③性别对肌苷酸的含量没有显著影响(P>0.05)。大部分品系不同性别间的5种鲜味氨基酸含量均达到差异显著水平(P<0.05)。

Abstract: 6 strains of 120 90-day-old Daheng quality broilers were collected, every strain including 10 females and 10 males, their contents of IMP and amino acids in the chest muscle were determined. The results indicated that: ①there were different IMP content among strains, and the highest content was strain S08; IMP content between strains were significantly different (P<0.05), except between S03 and S08, S02 and S06, S02 and S08×S01, S06 and S08×S01. ②The content of glutamic acid, glycine, aspartic acid, alanine and arginine showed differences among these strains. The hybrid strain S08×S01 showed the highest content of five amino acids. ③There were no significant differences between cocks and hens for most strains of IMP(P>0.05). There were significant differences between cocks and hens for most strains five amino acids content(P<0.05).

Key words: broilers; IMP; delicious amino acids
