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...

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...
