An experiment was conducted in 1996 and 1997 in semi-arid Niger, to determine the influence of supplementation (no supplement, millet bran + simple superphosphate, or millet bran + simple superphosphate + blood meal) for cattle and mulching (0 or 3 t ha-1 of Aristida sieberiana straw) on soil fer...

Many semiarid regions of Sub-Saharan Africa (SSA) are experiencing vast increases in human population pressure and urbanization. These augment the demand for agricultural products and have led to the expansion, intensification, and often closer integration of crop and livestock production systems...

The sustainability of nutrient transfers in integrated rangeland/cropland systems of the Sahel was examined in relation to the impact of livestock. Rangeland nutrient balances are considered in equilibrium whereas croplands lack the internal capacity to replenish nutrient off takes in grain and c...

Agricultural production in the semi-arid agro-ecosystems of the Sahel centres on cereal staple crops and pastoralism with increasing crop-livestock integration. Animals mobilize soil fertility through manure production, graze crop by-products, and transfer nutrients from distant pastures to crop...

Growing pearl millet and cowpea in combination with raising ruminant livestock is widely practiced in the Sahel. In this farming system, livestock feeding depends mostly on rangeland, fallows and cropland grazing. Nutritional constraints to grazing ruminants stem primarily from feed scarcity and ...

Grazing and herd management in sub-Saharan Africa is discussed in a broad ecological, agricultural and geopolitical context. A brief historical overview of the Development of the livestock sector is presented, followed by an assessment of feed supplies and livestock densities in major ecological ...
