A greenhouse experiment was carried out at the International Crop Research Institute for the Semi Arid Tropics (ICRISAT), at Sadord (13°15' N, 2°18'E), Niger, in conjunction with a feeding trial. Eight types of compost were made with millet stover (refusals and faeces with or without urine from s...

A classification of the major ruminant livestock production systems in West Africa is proposed. The proposed typology has two major classes of systems-sole livestock and crop-livestock. The sole livestock class has two systems (rangeland-based and landless) and the crop-livestock class has three ...

An experiment was conducted during the dry season in 1998 to determine the influence of supplementation with groundnut cake (GC) (0, 2.5, 5 and 7.5 g kg-1 LW) and phosphorus (P) (0 and 3 g day-1 animal) on diet and millet stover intake and digestibility, sheep growth rate and nutrient excretion. ...

Published and new data from experiments conducted in several range sites in Niger and Mali were analysed to assess wet season, dry season and year-round animal weight changes, stocking rates, forage availability, feed intake and faecal excretions of cattle, sheep and goats. Herbage availability o...

Short-duration rotation grazing was compared with deferred grazing in a 3-year experiment at ICRISAT, Niger. Short-duration grazing used a mixed herd (2 steers, 4 sheep and 4 goats) and cycles of 15-21 days in the wet season and 91 days in the dry season. Wet season grazing compared high (83-126 ...

In the short term, grazing of a 40-ha fallow in the Sahel, Niger, by sheep and goats reduced the standing herbage mass in the wet season and increased its disappearance during the dry season. The effects of stocking rate (62.5 or 125 k g liveweight/ha) and the proportion of sheep in the mixture (...
