GENETIC AND STATISTICAL ANALYSIS OF INDICATORS FOR BREEDING VALUE OF PRODUCING BOARS AT PIGS ARTIFICIAL INSEMINATION STATION

Abstract

It was determined that producing boars supplied to the republican stations of artificial insemination of pigs have high average daily weight gain values and age of reaching live weight of 100 kg - 643-731 g and 138-153 days. Producing boars were also characterized by high meat traits: backfat thickness varied - within 9,8-13,7 mm, height of the longissimus dorsi - 42,6-49,7 mm, meat yield - 57,7-62,5 %. The average in population values of traits that make a comprehensive assessment of the breeding value of boars are determined: average daily weight gain from birth to live weight - 665 g, backfat thickness - 10 mm, lean meat content - 60 %, number of nipples for maternal breeds (lines ) - 15, for paternal - 14, multiple pregnancy - 13,4 and 10,4 piglets respectively.
