Grazing has a great influence on the production costs of ovine extensive systems in the Spanish Southwest. This influence is greatly affected by climatic factors. Maintenance of these systems requires the organization of appropriate management strategies and this involves the technology transfer (T). The coordinated management strategies factors are the following: (i) adjustment of nutrient requirements to natural pasture availability (T: lambing seasons; use of forage crops for critical periods; body condition); (ii) production diversity (T: Meat-cheese) and type of products (feedlot or pasture plus suckling lambs; hard or soft cheese); and (iii) re-utilization of manpower (T: milking machine; coop cheese production).
