The pig sector in Nepal is widespread and mainly characterized by small-scale, mixed farms. Pig farming is dominated by small household (HH) production units of 1-2 pigs, which accounted for 86% (464,200 HH) of all households raising pigs in 2011. Production is typically low-input low-output, using unimproved breeds. The most common sources of pig feed are food industry by-products, kitchen waste, and grain by-products. Pigs therefore serve to convert limited waste and by-products of low value into high value food for consumption or/and sale.
