Summarises the impact of trypanosomiasis on development of trypanotolerant livestock. Describes current genetic research being carried out by collaborating national and international organisations in the African Trypanotolerant Livestock Network, and discusses the importance of conserving these g...

The potential of 3-year-old grazed pastures of Stylosanthes hamata, Chamaecrista rotundifolia and Centrosema pascuorum to contribute to subsequent maize production was investigated in subhumid Nigeria in 1993. All three legume pastures had the ability to give better maize grain yields than native...

Presents energy budgets and estimates of forage intake requirements developed for adult camels, cattle, sheep and goats managed by nomads of the arid Turkana district of north - western Kenya. Includes data on livestock activity patterns, diet quality, weight changes and milk yields with literatu...

Crop growth on acid sandy soils of the Sudano-Sahelian zone is primarily limited by the low amounts of organic matter and available mineral nutrients in the topsoil. The shortening of fallow periods with population growth, the exploitation of fire wood, spatial nutrient transfers by wind and wate...

The role of livestock in nitrogen cycling in mixed crop-livestock farming systems of sub-Saharan Africa was explored. Cattle were fed a range of diets to investigate the effects on partitioning of nitrogen between urine and faeces and on the chemical composition of the manures produced. The trade...

The integration of crop and animal production is well developed in the farming systems of Asia, particularly those in small-scale agriculture. There is marked complementarity in resource use in these systems, with inputs from one sector being supplied to others. Specific examples of the main crop...

Mixed crop–livestock systems are the backbone of African agriculture, providing food security and livelihood options for hundreds of millions of people. Much is known about the impacts of climate change on the crop enterprises in the mixed systems, and some, although less, on the livestock enterp...

Thiss paper presents an overview of the current status, problems and prospects for achieving a better nutrient balance to support varying levels of productivity from the three major livestock systems in Africa. In free range grazing systems, livestock nutrient deficiencies are mainly overcome by ...

Crop-animal systems, in which livestock play a multi-purpose role, are the backbone of Asian agriculture. In the future, increased productivity from livestock will be necessary in these systems to meet the increased demand for animal products, to alleviate poverty and to improve the livelihoods o...
