Title

Meatiness and meat quality depending on the genotype of pigs and their and feeding systems applied

Abstract

The objective of this study was to prove the influence of the genotype (Line 990 and 890) and feeding systems (ad libitum, diet and restricted) on carcass meatiness, backfat thickness, and basic meat composition (water contents, water contents capacity, protein and inte-rmuscular fat contents). Simultaneously, a carcass quality classification, based on a longissimus dorsi (mld) muscle, Was carried out. Various genotypes showed insignificant influence on meatiness and meat quality. It was proved, however, that the ad libitum feeding system had positive impact on the inter muscular fat content, which influences quality of meat obtained. The Ad libitum feeding system, in comparison to the restricted system, did not cause significant carcass meatiness reduction, and, at the same time, decreased the level of meat defects.
