摘要: 为培育优质猪品系,提高猪肉品质,本试验探索了陆川猪与杜洛克猪正反交F1代及其亲本陆川猪肌内脂肪含量和UCP3基因表达差异。试验分别选取陆川猪、陆川猪与杜洛克猪正反交F1代各8头,采用实时荧光定量RT-PCR方法测定肌肉中UCP3基因mRNA在不同品种猪中的表达量,并测定眼肌面积和肌内脂肪含量,以分析UCP3基因的表达量与脂肪和眼肌面积的相关性。结果显示,3组猪在眼肌面积、肌内脂肪含量和UCP3基因mRNA表达量上均差异显著(P<0.05),且正反交F1代均遗传了杜洛克猪体型大、陆川猪肌内脂肪含量高的优势,UCP3基因的表达量与猪眼肌面积呈极显著负相关,与肌内脂肪含量呈极显著正相关。初步推断UCP3基因可作为影响猪脂肪性状的主效基因。

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
