Sumario:The main objective of this study was to evaluate the production of meat during the dry period in Brachiaria hybrid cv. Mulato II pasture with three stocking rates, irrigated and spring fertilized. The research was conducted for 140 days at the Center for Research Turipaná of the Colombian Corporation of Agricultural Research (Corpoica), located at Cereté, Córdoba (Colombia). Were grazed 48 cattle, commercial zebu with average weight of 339 ± 29 kg in an area of 12 hectares. Three treatments (3, 4, 5 animals/ha) were evaluated with two replications in a randomized block design. Production, chemical and botanical composition, in situ degradability of dry matter and the daily weight gain was determined. Economic feasibility was determined by the benefit/cost ratio. The dry matter production was 1.925.16, 1.111.18 and 884.92 kg ha-1 for treatments 3, 4, 5 animal/ha respectively, detected differences (p<0.05). The quality of the pasture showed no difference (p>0.05). For daily gain analysis found differences (p<0.05), with gains of 1.07, 0.989 and 0.940 kg animal for treatments 3, 4, 5 animal/ha. The treatment 5 animal/ha provided the best indicators economical.
