The influence of night grazing on feeding behavior, nutrition and performance of cattle was studied. Twenty-four steers weighing 367 kg (SD = 76) grazed either from 0900 to 1900 (day grazers), 2100 to 0700 (night grazers) or 0900 to 1900 and 2400 to 0400 (day-and-night grazers) during 13 weeks. F...

The selective use by cattle of range resources in the Sahel was assessed in terms of quantity and nutritional quality of the herbage grazed and diet selected. Peak standing crop was 1951 kg ha -1 dry matter (DM) with 47.9 kg nitrogen (N) ha-1 and 7.4 kg phosphorus (P) ha -1. Esophageally fistulat...

A survey was conducted from February to June of 1997 among livestock herders in two villages of Niger, Kodey and Toukounous, on their perceptions, practice, and problems of night grazing. Cattle and sheep were the species that were taken out for night grazing by the herders. Small herd size an...

Integrated natural resource management (INRM) is considered in the context of evolving crop-livestock systems in West Africa and recent Developments in approaches for INRM research. The major crop-livestock systems, ranging from extensive grazing, through integrated crop-livestock farming to inte...

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 (...
