Five of each buffalos were bred by freely grazing and slaughtered at 35. 8-month old age to investigate the fatty acid composition and amino acid content in beef of Dehong buffalo,MD buffalo and ND buffalo. The results showed that,saturated fatty acid content of Dehong buffalo( 44. 33%) was significantly higher than that of ND buffalo( 41. 39%) and MD buffalo( 41. 48%)( P 【 0. 05),and the latter two were not significantly different( P 】 0. 05). The content of PUFA in Dehong buffalo( 53. 90%) was significantly lower than ND( 56. 83%) and MD( 56. 83%)( P 【0. 05),however,the n- 6∶ n- 3( 4. 25) of Dehong buffalo was significantly higher than ND( 3. 14) and MD( 3. 52)( P 【 0. 05). The content of amino acids in muscle was not significantly different between Dehong buffalo,MD buffalo and ND buffalo( P 】 0. 05),while the acidic amino acid content of Dehong buffalo was higher than that of MD buffalo and ND buffalo.展开更多
