滇南小耳猪与DLY商品猪背最长肌营养成分比较分析

Nutrient Composition Comparison of Longissimus Dorsi between Diannan Small-ear Pigs and DLY Commercial Pigs

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。

This study was conducted to compare the nutrient composition of longissimus dorsi be-tween Diannan Small-ear pigs and DLY commercial pigs.5 3 Diannan Small-ear pigs and 5 8 DLY commercial pigs were chosen and longissimus dorsi samples were collected to determine the con-tent 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 com-mercial pigs （P〈0.01）.However,the content of crude protein and crude fat were extremely sig-nificantly 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,1 1-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 ex-tremely 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.
