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...

In the tropics, numerous organizations have promoted multipurpose fodder trees (MPFT) with an emphasis on exotic species. These species have generally been selected and recommended by the research system through the conventional nutritional and agronomic experimentation for use as animal feed and...

Agriculture in the dry savannas is intensifying in response to increasing populations of humans and livestock. As a result, increased productivity demands are placed upon integrated crop-livestock systems and more emphasis is on the roles of legumes such as cowpea. Cowpea has the potential to fun...

Journal Article 2006

Autor: Jenet, A. Fernández Rivera, S. Tegegne, Azage Wettstein, H.R. Senn, M. Saurer, M. Langhans, W. Kreuzer, M.

This study tested the hypothesis that purebred Boran (Bos indicus) cows and crossbreds of Boran and Holstein respond differently to long-term changes of feeding level in nutrient partitioning to milk and body fat stores. A total of 27 cows of these two genotypes were subjected either to a low or ...

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...

Conference Paper 2002

Autor: Williams, Timothy O. Thornton, Philip K. Fernández Rivera, S.

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...

Autor: Somda, Z.C. Powell, J.M. Fernández Rivera, S. Reed, J.D.

Mixed farming systems in semi-arid West Africa rely on recycling organically bound nutrients to maintain soil productivity. The passage of plant biomass through ruminant livestock plays a major role in the nutrient cycles of this region. The feeding value of crop residues and browses and their im...
