TY - JOUR T1 - Estimating the total cost of fasciolosis in sheep and goats in Türkiye with a stochastic simulation model AU - Küçükoflaz, Mehmet AU - Sarıözkan, Savaş AU - Danacı, Umut Kamil PY - 2025 DA - August Y2 - 2025 DO - 10.31797/vetbio.1651857 JF - Journal of Advances in VetBio Science and Techniques JO - J Ad VetBio Sci Tech PB - İlker ÇAMKERTEN WT - DergiPark SN - 2548-1150 SP - 100 EP - 107 VL - 10 IS - 2 LA - en AB - This study aimed to estimate the total cost of small ruminant fasciolosis in Türkiye. For this purpose, official and previously published prevalence values were considered, and financial losses were calculated with current prices in 2024 year. A stochastic simulation model (Monte Carlo) was used to estimate the total cost due to fasciolosis. The weighted mean prevalence values were calculated for sheep as 3.47% (95% CI, 3.43-3.51%) and goats as 1.25% (95% CI, 1.20-1.30%). In total cost calculations, mortality losses, production losses and control expenditures were considered. As a result, annual total cost of fasciolosis for sheep was estimated to be $95.2 million (95% CI, $86.7-$104.2) and for goats $5.7 million (95% CI, $3.6-$7.9). The annual total cost of the disease in small ruminants was estimated to be $100.9 million (95% CI, $91.8-$110.2) and this amount is equally to 0.8% of total livestock production value in Türkiye. In conclusion, to reduce the impact of the disease for livestock sector and Turkish economy, producers should be informed about the quantity of losses and prevention/treatment procedures and, fasciolosis should be prioritized in national disease control/eradication strategies.
