The role of livestock in nitrogen cycling in mixed crop-livestock farming systems of sub-Saharan Africa was explored. Cattle were fed a range of diets to investigate the effects on partitioning of nitrogen between urine and faeces and on the chemical composition of the manures produced. The trade...

Implications of livestock feeding management on soil fertility in the smallholder farming systems of sub-Saharan Africa
An action research process was conductedwith communities in Gununo, southern Ethiopia (2000–2003), to develop alternative cropping strategies for achieving their food security and cash needs. Farmers identified three major production objectives depending on their household priorities and socio-ec...

Due to inadequate feed supplies for livestock production, farmers throughout the tropics and sub-tropics are being encouraged to supplement low quality basal diets with leguminous forage and concentrates. The varying quality (e.g. nitrogen, lignin and polyphenol content) of these diets will influ...
