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 ...

Cowpea is important for the provision of both grain for food and fodder for livestock but there is often a trade-off between production of the two. To better understand influences on grain and fodder production, and how these may be utilized. Research was conducted at 5 locations in West Africa u...

Three papers are reviewed in this paper. The first paper presents a model of biological processes to investigate long-term effects of soil and crop long-erm effects of soil and crop management strategies while the other two papers present approaches to study crop production strategies at the ente...

In response to on-going agricultural intensification, crop-livestock systems are becoming more important in West African farming systems. The role of livestock in providing stability to such systems, particularly through their interaction with the soil environment is unquestionable. Worldwide, th...

In semi-arid sub-Saharan Africa as in many dryland areas, livestock are an integral part of the farming systems. Livestock offer opportunities for risk coping, farm diversification and intensification and provide significant livelihood benefits to the poor. The ability of livestock systems to con...

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...

The influence of 0, 60 or 120 minutes of access to a grove of either Ziziphus mauritiana (Ziziphus) or Combretum aculeatum (Combretum) on forage intake and digestibility, animal growth and nutrient excretion was determined using forty intact Oudah sheep grazing for 7 h day-1 on poor quality dry s...
