Abstract: To compare the contents of amino acid in different parts muscle of Haimen goats(♂), Haimen goats(♀), Haimen goats and Boer×Haimen F1(♂) goats, these goats were raised under the same condition and slaughtered at 12-month-old to assay the content and variety of amino acid in buccinators, trapezius, triceps brachii, longissimus dorsi, biceps femoris, quadriceps femoris and gastrocnemius, and the amino acid was determined by the method of HPLC.The results showed that there were 17 kinds of amino acid and the content of glutamic acid was the highest in all the amino acid. The proline content of trapezius was significantly higher than that of triceps brachii, longissimus dorsi in Haimen goats(♂) (P<0.05).The content of serine, glycine, arginine, proline, cysteine and phenylalanine of trapezius were significantly higher than that of longissimus dorsi in Haimen goats(♀)(P<0.05).Compared with other anatomical muscles in Boer×Haimen F1(♂) goats, trapezius had the highest glycine values (P<0.05).There were no significant differences (P>0.05) in the content of essential amino acid, total amino acid and delicious amino acid among 3 different groups and 7 anatomical sites,and the content of delicious amino acid for the three groups were abundant. In summery, no significant differences were observed in most of these amino acid among the groups and anatomical sites, except for a little part of amino acid.But for the Haimen goats,especially Haimen goats (♂), had plenty of amino acid and showed a good delicate flavour.
