Abstract

Objectives: This study was conducted to assess poultry farmers' knowledge and practices regarding antibiotics, antimicrobial usage (AMU), and antimicrobial resistance (AMR), and to identify the sociodemographic factors of inappropriate use of antibiotics in commercial poultry farms in Bangladesh.

Methods: A qualitative survey of 140 farmers in Bangladesh was conducted from March to May 2019. A logistic regression model was used to identify factors associated with the inappropriate use of antibiotics.

Results: 47.1% of farmers were unable to explain antibiotics, 42.9% used antibiotics for preventive purposes, 4.3% used them as growth promoters, 25.7% used them as suggested by veterinarians, 42.9% used leftover antibiotics, 50% did not maintain antibiotics residual withdrawal period, and 98.6% did not know about AMR. In bivariable regression analysis, sex and primary occupation of poultry farmers, their knowledge about withdrawal periods for antibiotics, and no contact with veterinary surgeons (VS) were found to be significantly associated with the inappropriate use of antibiotics, while only 'no contact with VS' was identified in multivariable regression analysis.

Conclusions: The findings suggest an urgent need to improve understanding of antibiotics and AMR. Adequate supervision by veterinarians would ensure adherence to appropriate AMU patterns, and would limit the misuse of antibiotics and associated AMR development in farms.
