Pigs are one of the most important livestock species raised by smallholder farmers in the Philippines and Southeast Asia and are the main species raised specifically for the purpose of providing disposable family income. However, there is little baseline information on health problems, or on opportunities available to smallholder farmers to improve current levels of productivity in village pigs. This small project will study smallholder pig production at western Leyte and northern Benguet using two techniques - a cross-sectional study during the first 12 months followed by a longitudinal study of 20 months.
