Simple Summary: In total, 216 wild boars (Sus scrofa), a known host of roundworm (Ascaris suum) and giant thorny-headed worm (Macracanthorhynchus hirudinaceus), were examined. The infection rates of the free-ranged and captive populations were compared from June 2015 to June 2023 in Hungary. Of the 173 dissected wild boars from the wild, 57 (32.9%) were infected with A. suum, while 30 (69.8%) of the 43 individuals from the captive area were infected. The prevalence of M. hirudinaceus in the wild population was 9.25% (16 wild boars), while that of the captive animals was 34.89% (15 wild boars). The prevalence of A. suum in the entire population was 40.28% (87 wild boars), while the prevalence of M. hirudinaceus was 14.35% (31 wild boars). In the case of the examined helminths, the captive herd was 36.9% more infected than the herd living in the open area. Ascaris suum and Macracanthorhynchus hirudinaceus cause a large loss of yield in farm animals as well as in free-living and captive wild boar herds, thereby causing economic damage. This study compared A. suum and M. hirudinaceus infections in free-ranging and captive wild boars (Sus scrofa) in Hungary. The authors measured the A. suum and M. hirudinaceus infections of a 248-hectare wild boar garden and an 11,893-hectare free-living wild boar herd in the sample area. In all cases, samples were collected from shot wild boars. In total, 216 wild boars were examined from June 2015 to June 2023 in Hungary. Of the 173 dissected wild boars from the wild, 57 (32.9%) were infected with A. suum, while 30 (69.8%) of the 43 individuals from the captive area were infected. The prevalence of M. hirudinaceus in the free-living area population was 9.25% (16 wild boars), while that of the captive population was 34.89% (15 wild boars). In the case of the examined helminths, the captive herd was 36.9% more infected than the herd living in the open area. [ABSTRACT FROM AUTHOR]
