Avaliação Econômica do Uso de Suplementos Para Novilhos de corte em Pastejo no Período da Seca

Abstract

Brazilian beef cattle farming is mainly based on the pasture production system. Knowing that we have a productive seasonality of forage crops, and that it occurs during the dry period of the year, the use of food supplements for animals is necessary for us to have good animal productivity. The objective of this work was to evaluate profitability and costs, using extruded and/or crumbled multiple mixtures; in addition to the mineral mixture, for beef cattle grazing during the dry season. Three treatments were tested with eight animals each, two treatments using a single multiple mixture that went through one of the processes: extrusion (MME) or fine grinding (MMF), and a third control treatment being offered only mineral supplement (SM) to the animals. animals. The costs of supplementing the animals, the total profit and the net profit obtained in the activity were evaluated. When analyzing the data, no positive net margin and return on invested capital were found in any of the evaluated treatments. Total revenue was R$1,787.60 in the SM treatment, R$1,929.62 in the MME treatment and R$1,924.21 in the MMF treatment. The SM treatment had the lowest supplementation cost of R$32.50, 368.43 and 346.83% lower than the MME and MMF treatments, respectively, and the lowest cost per arroba produced in relation to the other treatments, of R$118,75. The net margin, of R$-79,94 and return of -4.33%, followed by the MMF treatment, which obtained a margin of R$-93.10 and a return of -5.67%, and by the MME treatment, with net margin of R$-94.71 and return of -5.74%. The latter being the one with the highest supplementation cost per animal, of R$152.24, and a daily rate of R$1.74, followed by MMF treatments, with a cost of R$145.22 and a daily rate of R$1.66, and by the SM with a cost of R$32.50 per animal and a daily rate of R$0.51. The total profit was R$-60,35 in the SM treatment, R$-93.10 in the MMF treatment and R$-94.71 in the MME treatment, although this has obtained the highest total revenue among the treatments. It is concluded that under the conditions evaluated, supplementation with multiple extruded or mashed mixtures and mineral supplements for cattle were not economically viable.
