Association of the Asp298Asn Polymorphism in the mc4r Gene with Back Fat Thickness in Pigs of the Large White Breed

摘要

—The association of the Asp298Asn polymorphism in the mc4r gene with the development of traites such as spinal fat thickness in pigs of the Large White breed from AF "Orzhitska" population was investigated. A tendency towards the development of thinner spinal fat was found in animals with the AG genotype. No significant difference was detected in the spinal fat thickness between animal groups with different genotypes of the mc4r gene caused by Asp298Asn polymorphism. The heterogeneous origin of the studied animals can be a possible cause of the absence of any statistically significant difference. A conclusion was reached that it was not expedient to use Asp298Asn polymorphism of the mc4r gene in the selection of pigs of the Large White breed from AF "Orzhitska" population.
