VARIABILITY OF INDICATORS OF PERFORMANCE AND MEAT TRAITS OF YOUNG PIGS OF BELARUSIAN MEAT BREED CROSSED WITH LANDRACE BREED

Abstract

The paper presents data on assessment of fattening indicators of young pigs of Belarusian meat breed crossed with Landrace pigs, as well as materials of variability of meat and fat traits of cross-bred animals. Thus, the assessment of the main indicators of fattening traits of young pigs of Belarusian meat breed crossed with Landrace pigs showed that the average age of reaching 100 kg of weight made 185.4 days, the average daily weight gain made 738 g, and the feed cost per 1 kg of weight gain made 3.58 feed units, slaughter yield - 68.7%, carcass length - 98.6 cm, backfat thickness - 25.1 mm, loin area - 41.6 cm², hind quarter weight - 11.2 kg. Assessment of variability level of indicators of meat-and-fat traits of animals obtained by crossing sows of Belarusian meat breed with Landrace boars showed there was a need for more stringent selection according to backfat thickness, since variability of this indicator showed the widest range from 6.4 to 18.8%.
