EVALUATION OF MORPHOLOGICAL COMPOSITION OF PIG CARCASS AT DIFFERENT MANAGEMENT TECHNOLOGIES

Abstract

Dependence of morphological composition of pig carcasses on the management technology has been determined. The weight of cooled carcass shows superiority of animals managed on deep bedding - by 0.5 %, by slaughter yield - by 1.6, by backfat thickness over 6-7th thoracic vertebra - by 6.2-7.3 %, 7cm below the sagittal line - by 5.7-6.9 %, respectively. Decrease in backfat thickness at point of 7 cm below the sagittal line compared with its thickness above the 6-7th thoracic vertebrae averaged 1.2-1.4 cm or 37.1-41.9 % in groups. The slaughter yield of animals managed on deep bedding is higher than of those managed on concrete floors by 1.6-1.9 %.
