Patterns and drivers of antibiotic use in small-scale broiler production systems in Lilongwe District, Malawi
Reducing the inappropriate use of antibiotics in food animals is a global priority to address antimicrobial resistance (AMR). We investigated practices and factors associated with antibiotic use in small-scale commercial broiler farms in Lilongwe district, Malawi. We used structured questionnaires t...

| description | Reducing the inappropriate use of antibiotics in food animals is a global priority to address antimicrobial resistance (AMR). We investigated practices and factors associated with antibiotic use in small-scale commercial broiler farms in Lilongwe district, Malawi. We used structured questionnaires to collect data on recent antibiotic use practices among 128 broiler farmers, who kept between 50 and 1 000 birds, from December 2022 to March 2023. Logistic regression analysis was used to identify risk factors associated with antibiotic use. Over half (53.1 %, n=68) of the farms reported using antibiotics at least once in the previous production cycle. Overall, 11 different types of antibiotics were used either for treatment and/or preventive purposes, with oxytetracycline (88.2 %), erythromycin (29.4 %), and enrofloxacin (26.5 %) reported as the frequently used. One-third of all antibiotic formulations contained multiple active antibiotic ingredients, with 12 % containing four antibiotics. Covariates associated with an increased likelihood of antibiotic use include disease incidence (OR=13.8, 95 % CI 5.27–42.50, p<0.001) and entry of wild birds into poultry houses (OR=3.56, 95 % CI =1.44–9.61, p=0.008). Our study highlights inappropriate usage of antibiotics, largely associated with reduced biosecurity and disease incidence. These findings underscore the need to strengthen veterinary services, reinforce regulations on antibiotic access and use, and farmer education programs promoting proper husbandry, biosecurity, and responsible antibiotic use. |
