Journal Article 1996

Autor: Powell, J.M. Fernández Rivera, S. Hiernaux, Pierre H.Y. Turner, M.D.

In the Sahel of West Africa, the productivities of rangelands, croplands and livestock are inextricably linked. Cattle, sheep and goats graze rangelands and crop residues, and their manure/urine is used to fertilize crops. Rangelands provide important feeds during the manuring period, resulting i...

The influence of 0, 60 or 120 min access to a grove of either Ziziphus mauritiana (Ziziphus) or Combretum aculeatum (Combretum) on forage intake and on the digestibility, growth and excretion of nutrients was determined using 40 Oudah rams grazing for 7 h/day on poor-quality dry season pasture in...

Journal Article 2004

Autor: Schlecht, E. Hiernaux, Pierre H.Y. Achard, F. Turner, M.D.

Poor cropland fertility and a rapidly rising demand for food force Sahelian farmers to cultivate more land and shorten fallow periods. This mostly leads to a gradual decline in crop yields per hectare, which can be counterbalanced by the systematic use of livestock manure on cropland. To assess t...

An experiment, was conducted in semi arid Niger to determine the influence of supplementation with groundnut cake (GC) )0 g kg 1, 2.5 g kg 1, 5 g kg 1, and 7.5 g kg 1 live weight (LW)) and P (0 g day`' and 3 g day 1 animal 1) on diet and millet stover intake and digestibility, sheep growth rate, ...

In the Sahelian rangelands biomass production is constrained by soil moisture in the drier (100-250 mm) parts and by soil nutrients in the wetter parts. Similarly, for a given Sahelian range, nutrient deficiency would be more prominent in good than in poor rainfall years. To test this hypothesis,...

Conference Paper 1996

Autor: Powell, J.M. Fernández Rivera, S. Hiernaux, Pierre H.Y. Turner, M.

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...

Conference Paper 1998

Autor: Schlecht, E. Fernández Rivera, S. Hiernaux, Pierre H.Y.

The influence of forage type, feed allowance and watering time on faeces and urine excretion by cattle, sheep and goats was studied. Higher amounts of nitrogen (N) were excreted during the day than during the night. The occurrence of defaecation and urination was highest at the time of getting up...
