Diet – largely herbivorous
The species is omnivorous, though stomach and faecal contents analyses reveal that vegetable matter, principally fruits, seeds, roots and tubers, constitutes about 90 per cent of the diet (34).
A field study of the Indonesian wild pig, S. s. vittatus, in Ujung Kulon National Park in Java, showed that these animals are predominately frugivorous, feeding on about 50 species of fruits, especially those of strangling figs (Ficus spp.), and that they are important seed dispersal agents (34). By comparison, analyses of the stomach contents of wild pigs (also S. s. vittatus) in agricultural areas of West Malaysia by Diong, revealed that sugar cane, tapioca and rice were most commonly eaten. Other items commonly consumed by these pigs included soil, earthworms, roots and other vegetable matter and, in mangrove areas, molluscs, crabs and other arthropods and even fish (34).
