To achieve this, we selected 20 farms with predominance of <em>B. decumbes </em>and <em>B. humidicola</em>, and divided the study into two phases: 1) static, in which we measured the socio-economic and the biophysical variables of the farm, the meadows, and the animals through characterization sheets; and 2) dynamic, in which we evaluated the productive performance of grasslands and animals. The qualitative variables were analyzed by contingence tables and correspondence analysis; while the quantitative variables, by descriptive statistics and, subsequently, multivariate statistics (PCA and clusters). The farms have 83±11 % of area in grasslands, 100 % divide and rotate the meadows, with periods of occupation of 3.71±3.33 days; in addition, 15 % of the farms have protein banks, 85 % depend on livestock activity, 80 % are owner managed, and 10% amend the soil. Weed control varies among mechanical, chemical, and mixed. The productivity of dry matter was 1,825.93±905.92 kg/ha/court, the grassland load capacity was 0.73 AU/ha, with milk yield of 1,492.95±416.55 kg/ha/year. In conclusion, the studied farms are dual-purpose family farms, with moderate technification and productivity.</p> ER -
