Изучена генетическая структура по гену PRKAG3 различных популяций, половозра- стных групп свиней пород белорусская мясная и крупная белая, разводимых в Беларуси. Аллель PRKAG3Q, ассоциированный с низкими показателями качества мяса, не иденти- фицирован. Частота встречаемости аллеля PRKAG3I в различных группах откормочного молодняка существенно не различалась и составила в среднем 0,30.Установлена тенденция положительного влияния аллеля PRKAG3I и генотипа PRKAG3II на следующие признаки откормочной и мясной продуктивности молодняка: возраст достижения массы 100 кг, затраты корма на 1 кг прироста, среднесуточный при- рост, длина туши, масса задней трети полутуши и площадь «мышечного глазка», а также на показатели качества мяса: уровень рН, потеря мясного сока при нагревании, влаго- удерживающая способность, содержание внутримышечного жира и протеина.

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.
