Influence of genotype on the share and distribution of muscle, fatty and bone tissues as well as commercial and energy value of pig carcasses

Research was carried out on the carcasses of Large White, Swedish Landrace and Line 3. Carcasses were dissected after Weniger et al.(1963) method. Carcasses of Line 3 (57, 10%) and Swedish Landrace (56.49%) had approximately the same muscle tissue share whereas Large White carcasses had a lower muscle tissue share (50.99%). Different distribution of muscle, fatty and bony tissue in carcasses of the investigated pig genotypes was determined. Carcasses of Line 3 and Swedish Landrace, which had approximately the same meatiness, also differed in the share of muscle, fatty and bony tissue. The largest share of ham tissue and abdominal rib part in pig carcass weight was determined in Line 3 (20.29%, i.e. 10.43%). Muscle tissue of back, shoulder and neck had the highest share in the weight of Swedish Landrace carcasses (10.96%, 10.94%, i.e. 6.47%). As a consequence of different tissue shares and distribution, different sales value of pig carcasses of alanlyzed genotipes was determined. Higher commercial value was genotype carcasses with higher muscle tissue share - Swedish Landrace and Line 3 and lower in Large White carcasses. Tissue arrangement, i.e. their composition had significant influence on commercial carcass value. Of total 20 right dissected carcasses of each genotype, the largest number of Large White carcasses (11) belonged to commercial class “U”, whereas the largest number of Swedish Landrace carcasses (14 i.e. 16) and Line 3 belonged to class “E”. Energy value of Swedish Landrace carcasses and Line 3 was the same and statisticantly lower than energy values of Large White carcasses.
