A Review of Traditional Technologies Based on Literature and Field Experiences Livestock play an important but variable role in both rural and urban societies. At the request and with the support of the Japanese Government, FAO has compiled experiences of livestock keeping from different parts of the world, categorized by production systems, to make it easier for interested people to select ideas for their own conditions. This document presents a sample of such technologies intended for livestock keeping in urban and peri-urban areas. It describes the livestock production system in traditional sectors and identifies constraints. Suggestions for improving production in the livestock sector are given and a literature list is included for further reference.
