Abstract: In order to breed high quality pig strain and improve the pork quality,the intramuscular fat content and the differences of UCP3 gene expression were studied in Luchuan pigs with Duroc reciprocal cross F1 and its parents Luchaun pigs.8 head of Luchuan pigs,Luchuan pigs with Duroc reciprocal cross F1 generation were respectively selected to analyze the correlation of UCP3 gene expression with intramuscular fat and eye muscle area.Expression of UCP3 mRNA in muscles of different pig breeds were measured by Real-time RT-PCR,and the eye muscle area and intramuscular fat content were measured too.The results indicated that the eye muscle area,intramuscular fat and the UCP3 gene expression were significantly different in the three groups of pigs (P<0.05).The crossbreds inherited the big body size of Duroc,and the high intramuscular fat content of Luchuan pig.The extremely significantly negative correlations were observed between UCP3 gene expression and the pig eye muscle area,the extremely significantly positive correlations were observed between UCP3 gene expression and intramuscular fat content.UCP3 gene should be the main candidate gene for fat trait research in pigs.

Key words: Luchuan pig; reciprocal cross; intramuscular fat; UCP3 gene; correlation
