<p>The study was conducted in 16 units producing milk (UPM) on small extent (< 300 liters/day) in towns located at Jaboticabal - SP rural development office of. Data were collected through observations and interviews with producers, aiming at characterizing the regional system of milk production in small-scale properties, facilitating grouping them by similarity and assisting them on decision making. Using the techniques of main component analysis, it was possible to reduce 22 original variables to nine, and then observed UPM clustering by using cluster analysis. So four groups were made in which it was possible to observe the relationship trend among variables: size of property, land used in cattle milk, degree of importance of dairy farming, efficient use of manpower, implementation of mandatory vaccinations, productivity, percentage of milking cows and its concentration per hectare, distance of UPM from the closest city. One can observe that, in general terms, on smaller farms (21.4 ha), dairy farming are more important, but with more pronounced sanitary deficiencies, as seen by the lack of vaccination. The highest yield (5896.20 L/ha/year) were achieved by the furthest UPM from the city (21.5 km), whereas larger farms (425 ha) had the worst yield (830.66 L/ha/year), but with better efficiency in the use of labor.</p> <br /> <br />
