Análise de sensibilidade da margem bruta da receita e dos custos do confinamento de diferentes grupos genéticos

Abstract: RESUMOAnálises de sensibilidade da margem bruta foram realizadas com dados de desempenho e custos de 149 animais confinados por períodos variáveis de acordo com acabamento de carcaça dos grupos genéticos: Nelore sobreano, Nelore desmamado, ½ Valdostana ½ Nelore, ½ Simental ½ Nelore, ½ Braford ½ Brangus, ½ Braford ¼ Angus ¼ Nelore, Brangus, ½ Canchim ¼ Angus ¼ Nelore e ½ Canchim ¼ Simental ¼ Nelore. Sensibilidade da margem bruta foi realizada com variações nos preços de venda da carne e de compra do milho, soja… Show more

“…Several studies involving the deterministic economic evaluation of feedlot cattle in different regions of Brazil (Restle et al, 2007;Lopes et al, 2011) agree with this comment, although with no sensitivity analysis. Analyzing economic aspects related to finishing cattle of different genetic groups in feedlots, Ferreira et al (2005) evaluated the sensitivity of gross margin and found that it was more sensitive to variations in the purchase price of thin animals, followed by the sale price of beef, soybean and finally, corn (diet-related).…”

“…A variação no preço de compra do boi magro pode sofrer influência de diferentes fatores como oferta e demanda, peso inicial e principalmente do grupo genético dos animais (Ferreira et al, 2005). Para o momento de compra e venda dos animais, a utilização de algumas ferramentas do mercado futuro pode auxiliar o pecuarista para diminuir o risco desta oscilação de mercado.…”

“…Many extensive systems need to acquire females for the reproductive cycle, and this practice in addiction to be a practical of high-cost has strong influence of market oscillations (9,18) . These systems make impossible the genetic selection, which as cites Jorge Júnior et al (19) becomes another factor that has a negative impact on the improvement of reproductive rates.…”
