Abstract
Objective - Foot-and-mouth disease (FMD) is a highly contagious viral disease affecting cattle, goat, swine, and many cloven-hoofed mammals worldwide. In Thailand, FMD is considered as a highly epidemic disease that severely affects dairy cows with distinct lesion of blisters on claws, lips, tongue or udders. The aim of this study was to determine the economic losses caused by the FMD outbreak in dairy farms in Mae Wang dairy cooperative, Chiang Mai province.
Materials and Methods – The cross-sectional analytical study with structured interview was used to collect the data that contain farm and farmer information, cost, income, and outbreak information form 51 dairy farms. The cost-benefit analysis was used to analyze the data.
Result - The result of this study showed that 51 dairy farm has highest production cost is 22.28 Baht/Kg, lowest production cost is 12.10 Baht/Kg (Median=16.54 Baht/Kg) and average production cost is 16.93 Baht/Kg. The highest fixed cost is 7.64 Baht/Kg, lowest fixed cost is 1.89 Baht/Kg (Median=3.60 Baht/Kg) and average fixed cost is 3.65 Baht/Kg. The highest available cost is 18.75 Baht/Kg, lowest available cost is 8.27 Baht/Kg (Median=13.28 Baht/Kg) and average available cost is 13.25 Baht/Kg. Three hundred and ninety-three out of seven hundred and four dairy cows (55.82%) showed clinical signs of FMD infection. As a preventive measure, the dairy cooperative informed farmers to stop selling raw milk to the milk collecting center for 15-30 days. The highest amount of discarded milk was at 15,000 kg while the lowest was at 1,000 kg (median=5,700 kg). The highest economic loss in a single dairy farm was at 267,000 Baht while the lowest loss was at 17,500 Baht (median=102,600 Baht). The total amount of discarded milk was 283,800 kg accounting for over 5 million Baht.
Conclusion-From the overall results, it was found that the extent of economic losses caused by foot-and-mouth disease in every dairy farms depended mainly on 3 factors, production cost, milk volume, and the peroid that unable to sell milk. As a result, it is likely that the economic loss is more severe in larger farms compared to smaller farms.
