CARCASS QUALITY OF PIGS OF DIFFERENT GENOTYPES ON FAMILY FARMS
SUMMARY
Within the project titled “Optimal pig production models on family farms of eastern Croatia”, researches have been curried
on in several family farms from three counties. Together with establishing the current state, researches on the possibilities
of improvement of reproductive, production and other quality traits of pigs have been started. This improvement should be
reached by getting the suitable sires and dams whose crosses (2- and 3-way crossbreeds) would give fattening pigs with
satisfying lean meat yield. Fattenng pigs as final products of pig productions were monitored in this study. Carcass quality
of 1592 fattening pigs from 6 family farms were determined at the slaughter line during 1999 and 2000 year. The highest
shares of lean meat determined by “two points” according to current national regulations method (1999) have been founded
in Hypor hybrid pigs (55.49%, n=51) and 3-way crossbreeds (SLxLW)xP (55.28%, n=692). Markedly lower results
have been recorded in GLxSL and SLxGL crossbred pigs (50.37%, n=204); GLxP (50.34%, n=195); GL and GLxP (49.00%,
n=96); SLxGL and GLxSL (47.51%, n=354). Poorer results achieved at those four farms could be explained by evidently
inapropriate feeding of fattening pigs which should, regarding the genotype, yield in higher share of lean meat.
