Carcass weight, condition and reproduction of wild boars harvested in north-western Poland

During the period from October 2008 till January 2009, in the carcass material assembled from the collective hunting of wild boars (n=165), the age structure of population, body masses and conditions of wild boars were assessed. Among the harvested wild boars, piglets constituted 35.8%, and subadults 53.9%, whereas adults only 10.3%. In females of all age classes corpora lutea and embryos were found. The average number of corpora lutea was 6.3 per female. The average litter size was 5.9 embryos per female. When divided in age classes, in older wild boars the average was 9.0 embryos per female and only 2.0 embryos in the yearling class. Of the embryos whose sex could be determined (n=19), 63.2% were females and 36.8% males.
