Abstract:

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.
