The Scandinavian wild boar (Sus scrofa) has increased in numbers the last decades and the population is estimated to around 60 000 individuals. However the Swedish population in bigger areas is difficult to estimate because of the lack of good survey methods. Studies have shown that there are some important factors related to the increased populations, the lack of natural predators and supplemental feeding, to name a few. In some hunting estates the feeding amount of oat can reach up to two-three tons a week distributed on different locations on the estate. With a high feeding distribution comes a bigger risk of spreading parasites and other diseases. The intention with supplemental feeding is to drag the wild boars attention from crops to prevent damage and attract them for selective hunting. The commonly parasitic burden with the domestic pig (Sus scrofa domesticus), many surveys has been done and it’s well known. However, there are no published studies on the parasitic fauna in the Scandinavian wild boars. This study sows that it is a differential in the prevalence in the fauna depending on geographical locations and it also shows the prevalence of nematodes in the Scandinavian wild boar in Sweden and the age on feeding places makes a different in the prevalence of parasites. The collected material and the study main objective have been to detect and determine the parasitic fauna in the Scandinavian wild boar. The intention of this study has been to set a ground for further research and to gain knowledge about the parasitic fauna of the Scandinavian wild boars.
