Impacto econômico do sistema intelligent precision feeder na produção e distribuição de rações para suínos em crescimento

Abstract

The objective of this dissertation was to study the economic impact of conventional (CS) and intelligent precision feeder (IPF-S) systems in growing and finishing pigs. The feed cost was the main variable used in the economic evaluation. A sample of commercial breeds of 1000 pigs was used from 26 to 105 kg LW during of 83 days. The diets were formulated based on linear minimum-cost approach. The feed costs were integrated into three modules (1) feed industry, (2) feed transportation, and (3) supply. Each module integrates several costs associated with specific conditions. In conventional system were produced 204 ton (60 of growing I, 72 growing II, and 72 finishing). In IPF system was produced the same quantity of CS (48 of diet A and 156 of diet B. The diet costs per ton in CS were R$ 591.49 for growing I, 525.79 for growing II, and 470.98 for finishing. In IPF-S these costs were 706.70 for diet A and 420.08 for diet B. The final average feed costs were of R$ 525.77 and R$ 487.52 in conventional and IPF system, respectively. In industry module the costs of worker and depreciation were similar, except for electricity, nine cents more cheap in IPF system. In this module, the feed cost was 7.57% lower in IPF-system. In feed transportation module, the cost of R$ 11.81 was the same for both systems. In feeding module the cost of IPF system was R$ 4.07 higher than conventional one. The final feed cost was R$ 6.99 lower per animal in IPF system.
