ABSTRACT Quantitative RT-PCR was applied to measure the relative expression levels of the adipose differentiation-related protein (ADFP) gene, fatty acid transport protein 1 (FATP1) gene and apolipoprotein B (ApoB) gene in subcutaneous fat, abdominal fat, liver and muscle at five growth stages (28, 49, 70, 91 and 112 d) to determine the effect of the expression ofthese genes on fat deposition in Daweishan Mini chickens.The relative expression of ADFP gene mRNA in the abdominal fat andthe liver was significantly different between 49 d and 70 d (p<0.05). The relative ApoB gene expression on 91d was higher in the liver, followed by muscles,subcutaneous fat, and abdominal fat, and was significantly higher in the liver than in the other three tissues. FATP1 gene expression in the liver presented a significant positive correlation with subcutaneous fat thickness (p<0.05). The results of this study suggest that the three genes may control the fat development in Daweishan Mini chicken.
