With the objective of determining the productive reach in bovine Cebú when using as supplement Norgol + molasses-urea to 3 % during the stage of growth-it feeds low shepherding system, 60 properly uniformed toretes was used as for weight and characteristic racial conforming to subjected four experimental groups at nine daily hours of shepherding, on grass PITILLA (Dichantium annulatum) + Tejana (Paspalum notatun) of regular quality; 3 kg of forage of Penisetum Cuba CT - 115; 1.0, 1.5 and 2.0 kg of Norgold for the groups I, II, III and IV, respectively and salt mineral and it dilutes ad libitum. The weight alive initial was determined and final, absolute growth, daily half gain and I consummate as well as was considered the benefit/cost. The animals of the treatment four were able to reach 401 kg of live weight , that is to say, 47.43 % of their weight regarding the weight live initial in 180 days and like average, for the whole period, a daily half gain and conversion of 716.66 g and 10.37 food kg / kg of weight lives respectively. It concludes that the treatments where it is included 2.0 and 1.5 Norgold kg respectively they achieved earnings daily stockings and conversion alimentary superiors significantly (P < 0.05) to the systems that traditionally have been orchestrated with the help of molasses-urea and the employment of other by-products, as well as the meat production that is achieved allows a relationship positive benefit / cost, that which means that the system is feasible, productive and economic.
