Sažetak
The aim of this study was analyze reproductive performance of wild boar in different habitat over a 7-year period (2006-2012). A total of 468 pregnant females and 2, 819 fetuses were analyzed, the mean number of fetuses was 6.02 (median=6) per animal (4.62 per juvenile, 6.39 per yearling and 6.77 per adult). In litters, male-biased fetuses occurred significantly more often than female, the overall fetal sex ratio is 1:0.86. Positive reproductive traits increased up to 90 kg of live body weight and then decreased. The reproductive parameters observed in our study reflect a relatively high reproductive capacity compared to the populations in southern and northern Europe, but are comparable with some populations in central Europe. Concerning habitat conditions, it is obvious that they influence the reproductive performance of females, and therefore must be included in management plans.
