摘 要：
为了比较扬州鹅及其杂交组合肉用仔鹅肌肉中氨基酸和肌苷酸(IMP)含量,试验以扬州鹅(A×A、B×B)及其4个杂交配套组合(B♂×A♀、K♂×A♀、D♂×A♀和C♂×A♀)共6个群体的肉用仔鹅分别作为对照组和试验组,采用氨基酸自动分析仪、高效液相色谱仪测定肌肉中氨基酸和IMP的含量。结果表明,公鹅胸肌中,除谷氨酸(Glu)、丙氨酸(Ala)、总氨基酸(TAA)、必需氨基酸(EAA)、鲜味氨基酸(DFAA)外,其他氨基酸含量在各组间均存在显著或极显著差异(P<0.05;P<0.01);各试验组一磷酸腺苷(AMP)、IMP含量均显著高于对照组A×A(P<0.05)。公鹅腿肌中各组间天冬氨酸(Asp)、Glu含量存在显著或极显著差异(P<0.05;P<0.01);试验组C×A、K×A肌苷(INO)含量均显著高于两对照组(P<0.05)。母鹅胸肌中各组间甘氨酸(Gly)、甲硫氨酸(Met)、精氨酸(Arg)含量存在显著或极显著差异(P<0.05;P<0.01);试验组K×A IMP含量显著高于两对照组(P<0.05)。母鹅腿肌中各组间Asp、Glu、Met、Arg含量均存在显著或极显著差异(P<0.05;P<0.01);试验组K×A IMP、IMPc含量均显著高于对照组A×A(P<0.05)。公、母鹅胸肌中次黄嘌呤(HYP)含量试验组C×A显著高于对照组A×A(P<0.05),试验组B×A AMP含量显著高于两对照组(P<0.05)。公、母平均腿肌中各组间Ala含量存在显著差异(P<0.05);试验组K×A、D×A AMP含量均显著高于两对照组(P<0.05)。由此可见,扬州鹅杂交配套组合在一定程度上提高了肌肉中氨基酸和肌苷酸含量,改善了肉品质。

摘 要：
This study was aimed to compare the content of amino acid and inosine monphosphate(IMP)in muscle of Yangzhou geese and its crossbred combinations.Yangzhou geese(A×A,B×B)and its 4 different crossbred combinations(B♂×A♀,K♂×A♀,D♂×A♀ and C♂×A♀)were used as control and test groups,the contents of amino acid and IMP were detected by amino acid automatic analyzer and high performance liquid chromatography(HPLC),respectively.The results showed that in the chest muscle of male geese,the content of other amino acids in all groups were significant or extremely significant differences except for Glu,Ala,total amino acid(TAA),essential amino acid(EAA)and delicate flavor amino acid(DFAA)(P<0.05;P<0.01),the contents of AMP and IMP in group A×A was significantly higher than that of in control group(P<0.05).In the leg muscle of male geese,the contents of Asp and Glu in each group were significant or extremely significant differences(P<0.05;P<0.01),the content of INO in groups C×A and K×A were significantly higher than that of in two control groups(P<0.05).In chest muscle of female geese,the contents of Gly,Met and Arg were significant or extremely significant differences(P<0.05;P<0.01),the content of IMP in group K×A was significantly higher than that of in two control groups(P<0.05).In leg muscle of female geese,the contents of Asp,Glu,Met and Arg were significant or extremely significant differences(P<0.05;P<0.01),the contents of IMP and IMPc in group K×A was significantly higher than that of in control group A×A(P<0.05).In the chest muscle of male and female geese,the average content of HYP in group C×A was significantly higher than that of in control group A×A(P<0.05),and the content of AMP in group B×A was significantly higher than that of in two control groups(P<0.05).In the leg muscle of male and female geese,the average content of Ala was significant differences(P<0.05),the content of AMP in groups K×A and D×A were significantly higher than that of in two control groups(P<0.05).In conclusion,Yangzhou geese crossbred combinations could improve the contents of amino acid and IMP in muscle,and the study demonstrated that crossed combination had better meat quality.
