[Distributions of polymorphism of ADD1, MC4R, H-FABP gene, associated with IMF and BF in 3 populations in pig].
Different breeds of pigs varied in traits of meat quality, especially between local abroad varieties. Intramuscular fat content (IMF) and back fat thickness (BF) have extra difference between Chinese breeds and foreign breeds. We have known that polymorphism of H-FABP, MC4R and ADD1 gene associated relation with IMF or BF in recent research. The Meishan, Sutai and Duroc x Landrace x Yorkshair become experimental animal in this research. Result show three breeds have different IMF and BF because different distributions of polymorphism three genes. Meishan has particular genetic background, so it should be protected. The results of associated analysis show that the polymorphism of three genes was associated traits of IMF and BF, polymorphism of MC4R gene was not associated traits BF. The molecular marker can apply to pig breeding by molecular marker-assisted selection (MAS).
