The aim of this study is to explore the technical and economic aspects of  cattle farms in mountain areas and to identify their technical constraints  and potentialities. One hundred dairy cattle farmers were surveyed for seven  months. The results show that the average farm size is 13 dairy cows and  shows considerable variability at the sample level. For one-third of the  farms, stabling is almost permanent and feed concentrate used as supplement  (on average 7 kg /cow/day). 85% of the factors of production (useful  agricultural area and possession of tractor) are owned by 45% of the  breeders. Cow productivity averages is around 10.5 kg / day with two milkings  / day. In addition, the average self-consumption of milk is 6 kg / day, which  represents 2.8% of milk production. Feed expenses represent 90% of production  costs. Annual income range from 99 909 AD / livestock unit (LU) nearly 148  421 AD / livestock unit. This variation is a function of the endowment of  production resources. Subsidies for milk production represent 58% of the  average income of farmers, what shows the low yield of dairy cattle farms.  Today, with the drastic reduction in financial resources, dairy production  development policies should focus on strategies to improve cow productivity  and profitability in those areas.
