摘要
The aim of this study was to determine and compare field dressing percentage in free-living wild boars from lowland (Spacva) and hilly (Papuk) habitats in Croatia. The obtained data indicate a better dressing percentage for wild boars from the Papuk region, with mean values of 77.35% for piglets, 79.61% for yearlings, 80.1% for subadults and 81.93% for adults. The dressing percentage for wild boars from the Spacva region was on average 75.10% for piglets, 73.68% for yearlings, 74.85% for subadults and 63.24% for adults. Furthermore, the internal organs were divided into eatable (heart, liver and kidneys) and non-eatable viscera. Of the complete viscera weight, the eatable part represented 17.57% in piglets, 17.97% in yearlings, 13.37% in subadults and 15.69% in adult boars from the Papuk region. The same values for the Spacva region were 19.79% in piglets, 14.06% into yearlings, 12.87% in subadults and 8.67% in adults. The results obtained in this study indicate a better growth rate and dressing percentage for wild boars from the Papuk region. When the similar feeding potential and habitat characteristics of both hunting grounds are taken in consideration, the most possible explanation for the observed differences is crossbreeding of wild boars with domestic pigs. The nomadic keeping of domestic pigs in the area of Spacva remains a huge problem for the preservation of the pure, autochthonous wild boar genome.
