Abstract: Fasciola hepatica is a parasitic flatworm that causes fascioliasis, a significant disease in livestock leading to substantial economic losses in agriculture. This paper develops and analyzes a mathematical model that incorporates optimal control strategies to manage the transmission of F. hepatica. The model includes four control measures: pasture management, anthelmintic treatment, isolation, and snail control. Stability analysis demonstrates that the disease-free equilibrium is locally and globally stable when the effective reproduction number R0 is less than 1. The model exhibits a forward bifurcation at R0=1. Sensitivity analysis identifies key parameters that influence F. hepatica transmission. The use of muscicides is a highly influential parameter in the transmission of the disease. Pontryagin's maximum principle was applied to determine optimal time-dependent control strategies for cattle fascioliasis. Cost-effectiveness analysis, using the incremental cost-effectiveness ratio, shows that combining all four control measures is the most cost-effective strategy.
