Stomach contents of Japanese Wild boar in winter

Abstract

Stomachs of wild boars were collected from hunters in the central Japan. 134 contents were analysed and measured their volumes and weights. Some correlations were seen between the volume and the dry weight of stomach content. Vegetable items of the foods, such as rhizomes, were found in 95% of the samples, whereas animal items, such as earthworms, were found in 30%. Caloric estimation showed the animals lived under poor nutritional conditions in winter.
