Proceedings of the second Pastures Network for Eastern and Southern Africa (PANESA) workshop, held at the International Laboratory for Research on Animal Diseases, Kabete, Nairobi, Kenya, 11-15 November 1985 IDRC-MR165e November 1987 The International Development Research Centre is a public corporation created by the Parliament of Canada in 1970 to support research designed to adapt science and technology to the needs of developing countries. The Centre's activity is concentrated in five sectors: agriculture, food and nutrition sciences; health sciences; information sciences; social sciences; and communications. IDRC is financed solely by the Parliament of Canada; its policies, however, are set by an international Board of Governors. The Centre's headquarters are in Ottawa, Canada. Regional offices are located in Africa, Asia, Latin America, and the Middle East. Le Centre de recherches pour le développement international, société publique créée en 1970 par une loi du Parlement canadien, a pour mission d'appuyer des recherches visant a adapter la science et la technologie aux besoins des pays en vole de développement; il concentre son activité dans cinq secteurs: agriculture, alimentation et nutrition; information; santé; sciences sociales; et communications. Le CRDI est finance entièrement par le Parlement canadien, mais c'est un Conseil des gouverneurs international qui en détermine l'orientation et les politiques. Établi à Ottawa (Canada), il a des bureaux régionaux en Afrique, en Asie, en Amérique latine et au Moyen-Orient. ACKNOWLEDGEMENTS The editors are grateful to Mrs. C.

Box 21, Kikuyu, Kenya Introduction Non-ruminant smallholder farm livestock Smallholder ruminants in Kenya Smallholder livestock feeding systems Feed-resource options available to the smallholder Conclusions Acknowledgements References Introduction The use of agro-ecological zone delineation to define areas with similar natural production potentials and constraints has been found to be of considerable value for planning purposes in many countries (FAO 1978). In Kenya a comprehensive field survey of six provinces was carried out during the period 1977-1980 by the Ministry of Agriculture with assistance from the Federal Republic of Germany. This survey resulted in the publication of the Farm Management Handbook of Kenya in which the agricultural areas were classified according to agro- ecological potential (Jaetzold and Schmidt 1982). Maps were prepared for each District at a scale of 1:500,000. Seven major ecozones were identified, very largely on the basis of water availability, with subsidiary classification being based on combinations of altitude, temperature and soil-type parameters (Table 1). Table 1. Agro-ecological potential zones in Kenya Zone Climate type Water availability (rainfall/Eo) % of country 1 Humid >80 5 2 Sub-humid 65-80 5 3 Semi-humid 50-65 5 4 Transitional 40-50 10 5 Semi-arid 25-40 15 6 Arid 15-25 20 7 Pre-arid >15 40 Eo = Potential evapotranspiration. Source: Kenya Soil Survey 1982. Care is needed in the use of such classifications based on average conditions. Variation in the climate in any particular season can shift the effective zone boundaries considerably (Downing et al. 1985). However, using the average classification, the small-farm sector to be considered in the
