This paper outlines the role of livestock in integrated nutrient management in semi-arid west Africa. Farmers' strategies in the use of animal manure as well as research efforts to better understand the process of nutrient cycling through livestock in mixed farming systems are described. It 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...
