Adipose differentiation-related protein (ADFP) is a fatty acid-binding protein that can promote the absorption of long-chain fatty acids. However, few results have been published regarding its role in Yunnan Native chicken breeds. The aim of this study was to determine ADFP gene tissue-specific expression in Piao chickens (PC) and Wuliangshan black-bone chickens (WBC) by RT-qPCR. The ontogenetic expression levels of the ADFP gene were significantly different during growth and development phases in the subcutaneous fat, liver, and pectoralis muscle of PC, and in the subcutaneous fat, liver, and pectoralis muscle of WBC (p 0.05). Individual tissue-differential expression levelswere detectedon d 91 and 112 in PC, with highest levels determined in abdominal fat and subcutaneous fat, respectively. However, in WBC, the highest levels were determined on d 49, 91 and 112 d in the pectoralis muscle and liver. Correlation analysis revealed ADFP expression level in liver of WBC was significantly related with LW and HC (p 0.05), while no significant correlations with carcass fatness (CF) were found in PC (p>0.05). The results suggest ADFPdifferential expression in the liver and pectoral muscles of PC and WBC during the growth and development phases (p 0.05). The observed expression patterns indicate that the ADFP gene plays an important role in lipid metabolism of PC and WBC, and that these patterns are expressed differently in the tissues of different chicken genotypes.(AU)
