Résumé
To provide a detailed description of the role of livestock in the farming systems of Kakamega and Siaya districts in western Kenya, a year-long monitoring survey was conducted on 80 farms. Changes in household demography, land, and capital resources, status of field crops, and specific information on livestock was collected. Included were monthly variation in births, deaths, and herd composition as well as milk production, feeding practices and forage quality. Constraints on the system are identified from the survey data and potential interventions are discussed. With 1500-2000 mm annual rainfall bimodally distributed, Kakamega has high potential agriculturally. Siaya represents a medium potential zone with 1100 mm annual rainfall. As farm sizes were extremely small (x = .9-1.1 ha) food production was the primary activity. Food crops were planted on 64-70% of the farm area in both districts, with the balance of land in fallow. Very few cash crops were grown. The productivity of the farm systems was low ; maize yields from maize/bean intercrops, the principal crops, were 980 and 1786 kg/ha in Siaya and Kakamega. Ruminants were found on 61% of all farms although herd size was usually less than 10 animals. Principal species were zebu and crossbred cattle, native hair sheep and east african goats. Livestock were kept for a variety of reasons ; the principal uses included capital storage, milk, and manure production. Only cattle were milked and productivity was low (300-400 kg/lactation). Ruminant ownership represented a strategy farmers used to exploit land such as common grazing areas they had no other right to, thereby increasing the farm’s productive resources. Inadequate nutritional resources were the most important constraint to increased productivity of livestock. A dual purpose goat intervention, though not likely to replace cattle, has potential for subsistence milk production on farms not presently able to support cattle. Potential to increase feed production without decreasing food crop yields is discussed. The importance of viewing livestock production as an integrated component of farming systems is stressed.
