Abstract:

The experiment was carried out to study the composition and contents of fatty acids of Nanyang Black pig, and to provide a theoretical basis for the protection and exploitation of local pig genetic resources in China. 12 Nanyang Black pigs and 12 Large White pigs were chosen, and the composition and contents of fatty acids in longissimus dorsi muscle were measured, and the quality of fatty acids was comprehensive evaluated from nutrition, health, flavor and storage aspects. Monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA), 12-16 carbon saturated fatty acids (SFA1), other saturated fatty acids (SFA2), unsaturated fatty acids (UFA), saturated fatty acids (SFA), SFA2/SFA1, MUFA/PUFA, essential fatty acid (EFA), conjugated linoleic acids (CLA), PUFA/SFA and ω-6 PUFA/ω-3 PUFA were used as the indexes of multiple comparison. The results showed that there were 30 kinds of fatty acids were detected and 23 of them had significant or extremely significant differences between the two pig breeds (P<0.05;P<0.01). Nanyang Black pig had higher values of above measured indexes than that of Large White pig in addition to SFA2/SFA1 and ω-6 PUFA/ω-3 PUFA. 11 indexes such as SFA1,MUFA,PUFA,SFA,UFA, UFA/SFA,SFA2/SFA1,PUFA/MUFA, EFA,CLA, PUFA/SFA and ω-6 PUFA/ω-3 PUFA differed significantly or extremely significantly between the two pig breeds (P<0.05;P<0.01), while SFA2 and PUFA/MUFA had no significant differences between the two pig breeds (P>0.05). In conclusion, the fatty acids of Nanyang Black pig were significantly better than that of Large White pig.
