A survey that gathered information about farm structure, grazing system, feeding and reproductive management was conducted in 181 farms. Parda de Montaña is the main breed regarding cows (92.4%), heifers (95,3%) and calves (84,1%). Bulls belong to Parda de Montaña (65%) breed but also Limusine, Charolaise and Blonde d'Aquitaine. Farms had an average size of 53.6 cows. Feeding depends largely on grazing in different forage resources, from June to October in high mountain ranges, in spring and autumn in natural meadows and forage crops. In winter most farms kept cattle indoors, where cows are fed hay, straw or silage. Most of the farms sell calves after weaning (5.5 months) and grow their heifers for replacement. Cows are mainly bred by natural service with bulls, which are from own farm or shared. Calving is prevented during the summer period. Age at first calving is 24-32 months. Most of the farms intend to maintain the herd size whereas 29.3% mean to increase it.
