Sustainability of semi‐arid extensive livestock systems in Senegal:elements for modelling animal‐ plant interactions

摘要：

In the Sahel cattle often graze free during the dry season (8 months).This system allows feeding cattle on rangelands and crop residues and recycling manure to maintain crop field fertility.The matter recycling depends on animals. daily circuit which depends on localisation of the well, the night park,and fenced areas.To evaluate long‐term sustainability of such a system both animal performances and matter transfers are approached by modelling animal behaviours.
