Home ranges of pigs are smaller during the dry season than during the wet season. During the dry season pigs preferred cool moist canyon bottoms due to a physiological need for free water. Dense vegetation was more actively sought after than open areas such as grasslands. Oat hay cultivations were also heavily exploited. Females are known to have about five young every 0.86 years and some females have two litters per year. In this study fertility continued to increase with age until it peaked at two to three years of age. 58% of piglets died before weaning.
