Based on bovine density (FAO, 1999), livestock systems distribution, proportion of oxen in the cattle herd structures and system-specific information on the use of bovine draught power to estimate oxen-working days per km2. Part of a study "Cattle and small ruminant production systems in sub-Saharan Africa: a systematic review" (FAO, 2002).

Based on bovine and human population densities (FAO, 1999), livestock systems distribution, system-specific production parameters, calculations of output per animal to obtain milk offtake per capita were performed using the Livestock Development Planning System Version 2 model. Part of a study "Cattle and small ruminant production systems in sub-Saharan Africa: a systematic review" (FAO, 2002).

Based on bovine density (FAO, 1999), livestock systems distribution, system-specific production parameters, calculations of output per animal to obtain beef production density (output per km2) were performed using the Livestock Development Planning System Version 2 model.
