Análise econômica do uso de antibióticos na fase de recria de tilápias do nilo (Oreochromis niloticus)

Abstract

The creation of tilapia in Brazil is a promising source of income generation with low implementation costs and rapid return on invested capital. Aiming at a high profitability the realization of the economic analyzes are essential for the viability and success for the producer. The present work compared the technical and economic efficiency of two antibiotics licensed for aquaculture for the Nile Tilapia rearing phase. The first active of the products tested were oxytetracycline and florfenicol. The experiment was carried out in a fish farm in tanks network, using eight units, where 12000 animals were placed per tank, two treatments were carried out with four replications. With the results obtained, it was possible to demonstrate that the florfenicol-based drug presented better zootechnical indexes and economic results, presenting a higher profit margin (17.33%) and a higher survival rate (81.16%), higher than the treatment with oxytetracycline-based medicine.
