Abstract:
The genetic variations of microsatellites in intron 2 of the porcine adipocyte fatty acid-binding protein (A-FABP) genes were investigated in 420 pigs including Wuzhishan pig, Yimeng black pig, Hanjiang black pig, Laiwu pig, Beijing black pig, Min pig, Chenghua pig, Neijiang pig, Erhualian pig, Bama xiang pig and Large White pig. The results suggested as follows: (i)PIC of the Wuzhishan pig breed is the highest (0.7904) and 11 alleles were detected. Compared with Large White pig,Chinese pig breeds showed a great polymorphism of A-FABP microsatellites except Beijing black pig in which only 2 alleles were detected. (ii) Only Min pig, Bama xiang pig, Beijing black pig and Large White pig were in Hardy-Weinberg equilibrium. (iii) The analysis of genetic differentiation showed that the average value of the A-FABP gene differentiation of 10 Chinese pigs is about 40.83%.
