The influence of genotypes of pituitary transcription factor gene (POU1F1) and growth hormone gene (GH) on meat and fattening qualities in the crossbred pigs

Abstract

By the PCR-RLPH methods was determined the frequency of the genotypes of the POU1F1 / RsaI and GH / FokI genes in the population of hybrid pigs Yorkshire x Landrace x Duroc (n=149) and their effect on fattening and meat productivity. The genotype frequency of the POU1F1 gene was: EE - 0.187; EF - 0.691 and FF - 0.120). The frequency of the E allele is 0.533, and the F allele is 0.466. Pigs with the FF genotype compared with pigs with the EE genotype have a significantly large weight and half-carcass length, average daily weight gain, lower feed consumption per 1 kg gain and age at achievement 100 kg live weight (p <0.01). The genotype frequency of the GH gene was: AA - 0.047; AG - 0.416 and GG - 0.537. The frequency of allele A was 0.255, and that of allele G, 0.745. Pigs with the GG genotype compared with pigs with the AA genotype have a significantly greater mass (p <0.01) and a half carcass length (p <0.02), the average daily weight gain (p <0.001), less feed consumption per 1 kg gain (p <0.02) and the age at achievement 100 kg live weight. (p <0.05).
