ABSTRACT

Many animal health actions depend on the availability and appropriate use of veterinary drugs, including antibiotics. The objective of this work is to provide a profile of antibiotic prescription and consumption in the poultry sector, such as poultry layers, in order to propose solutions for improving antibiotic use in the urban municipality of Dubreka. The study found that all animal health workers are professionally trained, but only 62.5% are permanently employed on the farms. As there is no veterinary diagnostic laboratory in Dubreka, animal health workers in addition to observation of clinical signs perform autopsies to establish the diagnosis. As a result, 87.5% of them consider antibiotic therapy as a priority for all infections. In addition, 14.3% use anticox and alfaceryl for the control of avian diseases. The majority of poultry farmers, who have no previous training in poultry farming, practice self-medication of chickens (70.4%). In case of persistent clinical signs, they consult the health agent (30.6%). We identified fifteen (15) antibiotic molecules belonging to eight (08) families including tetracyclines, sulfonamides, quinolones and fluoroquinolones, macrolides, aminosides, diaminopyrimidines, polymyxins and nitrofurans for a total of 662.229 kg of active ingredient being sold from January to June 2019 by the four (04) veterinary medicine points of sale. The point of sale with the most sales is the point ''D'' with 45.66% of sales. The month of January is the one in which the most active ingredients were sold, with 70.82 kg. Poultry are more exposed to sulfonamides, which are anticoccidials, especially alfacox super and anticox. However, they have a higher exposure time for oxytetracycline 50% with 2159 kg d.
