Polymorphisms associated with resistance to infectious diseases in different breeds of pigs of the Belgorod Region of Russia

Using the PCR-RFLP method, we genotyped pigs for genes GBP1 (mutation c. [10A>G; 11A>G]), FUT1 G307A) and MUC4(A243G) associated with resistance to infectious diseases. A total of 188 boars four breeds (Duroc, Large White, Landrace Yorkshire) from Belgorod Region Russian Federation were studied. The highest frequency favorable genotype AG polymorphism GBP1E2, which is resistant pig respiratory syndrome, was characterized by Duroc breed (0.38). Eischerichia coli F18-resistant AA observed in population (0.19). And terms E. fibrium type F4 (K 88), GG White (0,23). In general, it can be noted that genetic studied predominantly only one disease.
