Abstract

The increasing livestock demand in developing countries raises concerns about endemic zoonotic diseases, such as bovine tuberculosis (bTB). Farmer behaviors and social contexts drive transmission, necessitating behavior change interventions. An epidemiological field survey was conducted to assess artificial insemination (AI) use and bTB incidence among dairy farmers in Madagascar, combined with socioeconomic interviews with 114 farmers in Malagasy from 2021 to 2022. A probit regression model analyzed farm-level bTB infection status as the dependent variable. AI was used by 14.1% (15 households), with 93.3% (14 households) employing natural bull mating. The herd-level bTB prevalence was 41.2% (50 cows), and 41.6% (47 households) owned at least one bTB-positive cow. AI use increased the risk of bTB, likely due to inadequate cleaning of AI equipment. Despite AI’s potential to improve productivity, improper implementation may increase the risk of bTB. These findings underscore the need for enhanced farmer education on bTB prevention and proper sanitation of AI equipment.
