Análise econômica de diferentes alternativas de desmame através de simulação

Abstract

The aim of this study was to make a systemic and economic analysis of the weaning methods used in beef cattle in Rio Grande do Sul. The analysis of the economic return of three methods was made through simulation: conventional tablet and interrupted at 90 days. The number of matrices which were used was 100, varying factors such as cost of implementing the method, the sale price and weight of the animals, pregnancy rate achieved with the method, current pregnancy rate of the property were taken into consideration. According to these values, the viability of the methods was simulated, the conventional one was used as control, it means, it had its implantation cost and profitability set to zero. The method of interrupted weaning was proved feasible for all observed scenarios, due to its low cost of implantation. Nevertheless, the early weaning method had its viability varying according to the sale price, sale weight and pregnancy rate achieved. We concluded that the feasibility of the methods depends on the market, price of raw material and products. However, the developed simulation model can be used in any reality, allowing the changing of all the variables leading to results that fit to any reality at any time.
