Abstract
The organic manures are the backbone of pesticide free food products and also the same is the culprit to transmit the antibiotics to food chain. The maximum concentrations of Oxytetracycline (OTC), Enrofloxacin (ENRO) and Chlorotetracycline (CTC) in poultry litter were 183 mg kg-1, 83 mg kg-1 and 726 mg kg-1, respectively and 72 mg kg-1, 52 mg kg-1 and 133 mg kg-1 in cowdung, respectively. During the composting process period, the antibiotics viz., OTC, ENRO, CTC were noticed in decreasing trend. The matured poultry manure recorded the OTC, ENRO and CTC concentration of 22, 18 and 162 mg kg-1, respectively whereas the vermicompost recorded the OTC, ENRO and CTC concentration of 12, 10 and 32 mg kg-1, respectively. From the present investigation, the poultry manure recorded more quantity of antibiotics viz., OTC, ENRO and CTC. It is also concluded that the composting process had significant reduction of antibiotic concentration compared to raw materials.
