    Describes effects of feeding Bunaji cows supplements of cottonseed cake, molasses-urea or fodder bank on birth & 1-year weight of calves and their viability to 1-year, and milk yield, for both calves & humans, of cows under an agropastoral management system.

    The main objective of ILRI's Sustainable Production Systems Programme is to improve human welfare through the development of more productive and Sustainable crop-livestock sytems in developing countries. The programmes' focus is on market-oriented smallholder crop-livestock systems. In order to improve the productivity and sustainability of these systems, biological, environmental and socio-economic constraints have to be overcome. Therefore, opportunities for changing the systems in a sustainable manner have to be carefully identified and chosen.

    A project proposal whose aim is to promote more appropriate resource management on smallholder crop-livestock farms in East Africa is described. Prototypes of mixed farming systems will be developed to characterise farming systems according to their management objectives. These prototypes will then be used to map improvements of the farming systems by combining prototyping and simulation modelling. Scenarios will be explored to assess natural resource management interventions that promote sustainability of these prototype-farming systmes.

    This report is divided into seven sections. The first section deals with biology of Stylosanthes and its importance in West Africa and Latin America. The second section presents papers on the screening and evaluation of Stylosanthes germplasm. This includes genetic diversity, genetic resources, species screening, multi-locational testing and evaluation of accessions. The third part discusses the dynamics, nutrient requirements, and pests and diseases of Stylosanthes species. Section four looks at Stylosanthes-based pastures for livestock production.

    Kenya, Afrique, Afrique orientale

    Although soil fertility is recognized as a primary constraint to agricultural production in developing countries, use of fertilizer in Sub-Saharan Africa is declining. Smallholder farmers still rely heavily on livestock manure for soil fertility management. To explore the determinants of soil fertility management practices, including both the use of cattle manure and inorganic fertilizer, data are used from a sample of 3,330 geo-referenced farm households across Central and Western Kenya. A bivariate probit model is applied to jointly examine the use of the two technologies.

    Éthiopie, Afrique, Afrique orientale

    Formulation of cost-effective preventive control programmes for helminth infection in small ruminants should be based on sound epidemiological knowledge of the time relationship between contamination of pastures and the seasonal availability of infective larvae in a given geographic area. Epidemiological data generated from an on-station experiment involving the use of tracer lambs and monitoring of pasture contamination levels in the central Ethiopian highlands clearly showed a distinct seasonal pattern of nematode infection in sheep.
