Abstract

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.

Key words: Diannan Small-ear pigs; DLY commercial pigs; longissimus dorsi; nutritient composition
