Analysis of PRKAG3 gene polymorphism and Belarusian meat breed of young pigs at fattening performance of different genotypes on the gene studied
Abstract
Genetic structure on PRKAG3 gene of different populations age and sex groups of Belaru- sian meat breed and Great white breed of pigs reared in Belarus was studied. PRKAG3Q allele associated with low meat quality was not identified. The PRKAG3I occurrence frequency in different groups of young animals at fattening did not differ considerably and made averagely 0,30.The tendency of PRKAG3I allele and PRKAG3II genotype positive effect on the following traits of meat and fattening young animals performance was determined: age of reaching 100kg of weight, forage spends per 1 kg of weight gain, average daily weight gain, carcass length,weight of rear third part of carcass and “loin” area as well as meat quality: pH level, meat juice loss at heating, moisture-retaining power, intramuscular fat and protein content.
