| Popis: | EnglishThe goal of the present study was to assess the economic viability relating to the risk of replacing corn with pearl millet in diets with 80% concentration for feedlot cattle confined for 89 days. Replacement levels were: 0, 33, 66, and 100%. The risk was estimated using Monte Carlo simulation, Spearman’s rank correlation test between input variables, stochastic dominance, and analysis of sensitivity. The expected average values ± standard deviation for net present value (R$/animal) were ± 71.74 ± 283.32, 91.23 ± 285.18, 196.05 ± 273.79, and 223.80 ± 267.96 for diets containing 0, 33, 66, and 100% of pearl millet, respectively. The probability of ≥0 net present value was 63.4, 66.1, 78.4, and 82.4%, respectively. The net present values were statistically different (P portuguesO objetivo do estudo foi avaliar a viabilidade economica relacionada ao risco da substituicao de milho por milheto em dietas com 80% de concentrado no confinamento de bovinos por 89 dias. Os niveis de substituicao foram: 0, 33, 66 e 100%. O risco foi estimado usando simulacao de Monte Carlo, correlacao de Spearman entre as variaveis de entrada, dominância estocastica e analise de sensibilidade. Os valores medios esperados ± desvio padrao para o valor presente liquido (R$/animal) foram de ± 71,74 ± 283,32, 91,23 ± 285,18, 196,05 ± 273,79 e 223,80 ± 267,96 para dietas contendo 0, 33, 66 e 100% de milheto, respectivamente. A probabilidade de valor presente liquido ≥0 foi de 63,4, 66,1, 78,4 e 82,4%, respectivamente. Os valores presentes liquidos foram estatisticamente diferentes (p Com base nos resultados da simulacao, a dieta de 100% de milheto mostrou a melhor viabilidade economica |
