A simulation model related to embryo transfer programs in bovine was carried out through a mathematical model directed to events, considering the dynamic of two resources: recipients and embryos. Individual answers of donors to consecutive collections and corresponding events in embryo transfer were not evaluated. The same protocol for superovulation was simulated for all the donor collections, using similar doses of hormones and drugs for all the animals. Recipients were synchronized using prostaglandin. Meantime, the number of viable embryos produced by donor and its variability were based at Monte Carlo random simulation process, which presupposed a negative exponential distribution of density of probability. Costs were inserted in the model through a basis scenery to calculate economic indicators of profitability (cost per pregnancy, Net Present Value and Internal Rate of Return). The analysis suggested the impracticality of the activity if it is carried out in the proposed scenery NPV (US$ - 25,042.04). An estimate average cost of US$ 512.25 and of US$ 426.01 was obtained by the proposed scenery to get a pregnancy at an optimized situation, (5/100; 5/190).
