Economic evaluation of different technologies for pasture recuperation

The aim of this study was to compare the economic viability of some technol ogies for recovery of degraded pastures, for a period of time, evaluating a nimal development under rotational grazing. The activities were conducted i n Brasilandia, MS, Brazil, studying six modules of 5 ha each. Modules T1 (c orn + Brachiaria brizantha), T2 (rice + B. brizantha), and T3 (rice + B. br izantha + Calopogonium mucunoides) had been renewed following the procedure s recomended by the "Barreirao System". Module T4 had been formed according to traditional regional procedures, with B. brizantha. Modules T5 and T6 w ere selected in the vicinity of the others, to serve as controls; B. humidi cola was predominant in module T5, whereas module T6 was predominantly form ed by B. humidicola and B. decumbens. Economic evaluation was based on cere al production, live weight gain and stocking rate. It was observed that in modules T1, T2, T3, and T4, exploration of beef cattle grazing on recovered pastures is a profitable activity. Pasture renewal according to agricultur al modules T1,T2, and T3 have advantages over the traditional models due to the cereal production which defrays the cost to recover the pastures.
