Abstract: Detect the adiponectin and insulin content of Chuanzang Black swine hybrid and DLY pig by enzyme-linked immunosorbent assay (ELISA) and analyze its relationship with intramuscular fat content.The results showed that the adiponectin content of Chuanzang Black swine hybrid of 90,110 and 130 kg body weight respectively were 82.49,79.15 and 82.49 μg/L,and insulin content respectively were 37.44,39.77 and 37.53 mIU/L;Adiponectin content of DLY respectively were 62.59,62.86 and 61.81 μg/L,and insulin content respectively were 48.48,46.45 and 48.29 mIU/L.There was no significant difference in different bodyweight of the same breeds (P >0.05),and there was very significant difference in different breeds of the same bodyweight (P <0.01).Correlation analysis showed that adiponectin and intramuscular fat content had a highly significant positive correlation (P <0.01),and insulin content and intramuscular fat content had a highly significant negative correlation (P <0.01),which prompt adiponectin and insulin might be achieved the overall regulation of intramuscular fat through blood.

Key words: Chuanzang Black swine hybrid; DLY; intramuscular fat content; adiponectin; insulin
