RELATION BETWEEN QUALITY TRAITS AND VALUE OF HALVES IN THE FATTENED PIGS PRODUCED FROM DOMESTIC AND IMPORTED PIGLETS

The research has been carried out on the fattened pigs carcasses of the groups A (n=86) and B (n=127). The fattened pigs of the A group were produced from the domestic piglets, acquired by crossing various breeds and hybrid parental lines, bred in the Republic of Croatia. The fattened pigs of the B group were produced from the piglets imported from Hungary. All individuals were fattened on one family farm, on the Prefect District County of Brod and Posavina territory. The carcasses' quality traits were established by the "DT" method (NN 119/99). Various values of the DEM/kg carcass mass in the A group, in the amount of 3,26 DM/kg, and in the amount of 3,44 DEM/kg in the B group, were acquired as the result of the statistically significant differences of the muscle tissue share in the carcasses, differing from 53,54% in the A to the 56,23% in the B group. Within the fattened pigs groups for the correlation coefficient and the regression coefficient established between the carcasses' mass, the thickness of the back fat and the m.l.d. as well as the share of the muscle tissue and the DEM/kg values of the carcass mass, was established with the following values in accordance with the groups: A -0,43** and -0,015**; -0.88** and -0,035**; 0,20 and 0,011; 0,93** and 0,058**, while the B group showed -0,09 and 0,003; -0,92** and -0,047**; 0,22* and 0,011*; and 0,95** and 0,057**.
