Planejamento e avaliação econômica de diferentes sistemas produtivos de pequeno porte de poedeiras de ovos marrons.

Abstract

The study aimed at planning the production of brown eggs in three small-scale farming systems, along with an economic evaluation of each of them. The comparative analysis among these systems aims to identify which one is more advantageous and profitable, taking into consideration aspects related to facilities, equipment, and inputs. To conduct the planning, the Lohmann Brown lineage manuals for cage production system and alternative systems (cage-free and free-range) were used as a basis for productive indices. The production cost analysis was carried out based on market research, followed by an economic analysis. The conventional system showed a benefit/cost ratio of 0.61, 0.68, and 0.71 in up to three production cycles, respectively. The cage-free system had ratios of 0.65, 0.77, and 0.80, while the free-range system had ratios of 0.76, 0.89, and 0.91. Although three production systems were planned with the expectation of achieving viability in up to three production cycles, none of them proved to be economically viable due to the low benefit-to-cost ratio. Therefore, it was estimated for six production cycles, where the benefit/cost ratio for the conventional system was 0.71 and for the cage-free system was 0.87, both still being unviable. However, the free-range system was viable in six production cycles with a benefit/cost ratio of 1.07, meaning it showed a profit of R$ 8,932.90 per month. Therefore, reducing the costs related to feeding in the planning could potentially result in a more favorable benefit/cost ratio and make it viable with fewer production cycles.
