ABSTRACT
The economic viability of finishing sheep on Tanzania grass under intermittent grazing was evaluated with four concentrate supplementation levels (0; 0.6; 1.2 and 1.8% LW), two herd separation systems (electric and net fence) and three pasture sizes (1.0; 3.0 and 5.0 ha). The analysis was carried out to determine the minimal necessary conditions to have a viable business. Net income, benefitcost ratio, net present value and internal rate of return with an interest of rate of 8.75% per year were verified. The total implantation cost and maintenance to each system was estimated according to Fortaleza/CE market. Sale price between R$ 2.60 to 3.20/kg LW was considered to estimate total budget. The pasture sized 1.0 ha was economically unviable for both kinds of system tested.The system with net fence was more expensive than the one with electric fence. For the systems with supplementation, data showed viability only for a sale price above R$ 3.00/kg LW and, in some cases, in areas above 5.0 ha.
