摘要
本文测定了长白猪、北京黑猪及东北民猪背最长肌脂肪酸及氨基酸的组成。结果表明：１，长白猪总饱和脂肪酸含量显著高于北京黑猪（Ｐ＜０．０５）及民猪（Ｐ＜０．０５），北京黑猪显著高于民猪（Ｐ＜０．０５）；民猪的总不论和脂肪酸含量显著高于长白猪（Ｐ＜０．０５），与北京黑猪差异不显著（Ｐ＞０．０５）；不同性别猪各脂肪酸含量差异不显著，２，３个猪种中１５种氨基酸及衍生物含量有显著差异（Ｐ＜０．０５）。民猪和北京黑猪赖氨酸的含量显著高于长白猪，北京黑猪苏氨酸含量低于长白猪（Ｐ＜０．０５）。不同性别个体间游离氨基酸组成除丝氨酸、缬氨酸、苯丙氨酸外，没有显著差异（Ｐ＞０．０５）。
This paper tested the fatty acid and amino acid compositions on Longissimus muscle of Landrace、Beijing Black pigs and Min pigs.The results showed:1,the percentage of total saturated fatty acid(TSFA) of Landrace is higher than Beijing Black pigs(P<0 05) and Min pigs significantly (P<0 05) , and Beijing Black pigs is higher than Min pigs significantly(P<0 05).Meanwhile,The percentage of total unsaturated fatty acid(TUFA) of Min pigs is significantly higher than Landrace (P<0 05) The effects of sex on the components of fatty acid are not significant(P>0 05).2,The contents of 15 out of 20 amino acids are significantly different among the three breeds(P<0 05). The level of lysine in Beijing Black pigs and Min pigs are significantly higher than Landrace (P<0 05) ,and the level of threonine in Landrace is higher than Beijing Black pigs(P<0 05).The level of amino acids are not significantly different between males and females with exception to serine,valine and phenyalanine.
