| 摘 要： | 本试验为比较研究滇南小耳猪与DLY商品猪肉的营养价值，分别检测了53头滇南小耳猪和58头DLY猪背最长肌肉的水分、粗蛋白质、粗脂肪、灰分、氨基酸及脂肪酸等营养成分含量，比较分析其差异性。结果显示，滇南小耳猪背最长肌的水分含量极显著低于DLY商品猪背最长肌（P < 0.01），粗蛋白质、粗脂肪含量极显著高于DLY商品猪（P < 0.01），灰分含量差异不显著（P > 0.05）；其中滇南小耳猪背最长肌的7种必需氨基酸（苏氨酸、缬氨酸、蛋氨酸、异亮氨酸、亮氨酸、赖氨酸、苯丙氨酸）、肉豆蔻酸、棕榈酸、油酸、顺式异油酸、11-顺-二十碳烯酸，饱和脂肪酸、单不饱和脂肪酸、总脂肪酸含量均极显著高于DLY商品猪（P < 0.01）。综上所述，滇南小耳猪与DLY猪相比具有更高的营养价值和开发价值。 |

| Abstract: | This study was conducted to compare the nutrient composition of longissimus dorsi between Diannan Small-ear pigs and DLY commercial pigs.53 Diannan Small-ear pigs and 58 DLY commercial pigs were chosen and longissimus dorsi samples were collected to determine the content of moisture,crude protein,crude fat,ash,amino acids and fatty acids.The results showed that the moisture content of Diannan Small-ear pigs was extremely significantly lower than DLY commercial pigs (P < 0.01).However,the content of crude protein and crude fat were extremely significantly higher than DLY commercial pigs (P < 0.01).And there was no significant difference in ash content (P > 0.05).The levels of threonine,valine,methionine,isoleucine,leucine,lysine and phenylalanine in longissimus dorsi of Diannan Small-ear pigs were extremely significantly higher than that of DLY commercial pigs (P < 0.01),and the content of myristic acid,palmitic acid,oleic acid,cis different oleic acid,11-cis-20 carbon olefine acid,saturated fatty acids,monounsaturated fatty acids and the total fatty acids in longissimus dorsi of Diannan Small-ear pigs were also extremely significantly higher than that of DLY commercial pigs (P < 0.01).In conclusion,Diannan Small-ear pigs had a better value in nutrient and development. |
