Knowledge affecting foot-and-mouth disease vaccination behavior: traditional dairy farmers in the dry zone of Sri Lanka

The aim of this study was to identify social and farm factors influencing the knowledge of foot-and-mouth disease (FMD), factors influencing participation in FMD vaccination, and vaccination coverage. The study was conducted with 180 traditional dairy farmers who were engaged in cattle and buffalo farming located in three veterinary ranges of the Ampara district in the eastern province of Sri Lanka, during September and October 2019. The probit and tobit regression models were applied to determine the factors. On an average, the scores for knowledge of FMD and hygiene management were calculated as 54.5% and 49.2%, respectively. Farmers' knowledge of FMD was strongly associated with gender, level of education, and participation in the farmer training program (p < 0.01). The vaccination behavior was enhanced significantly by the number of animals, farming experience, knowledge of FMD score (p < 0.05), and hygiene management score (p < 0.1). It was revealed that social and farm factors contributed to the knowledge of FMD and vaccination behavior. Therefore, we recommend that the livestock educational training program will motivate better participation in the FMD control plan in Sri Lanka.
