2.1. Brazilian merganser
As part of the Brazilian merganser Conservation Program, the Itatiba
Zoological Park (Sao Paulo state, Brazil) carries out a successful
breeding project. In October 2019, an 8-day-old Brazilian merganser born
in the breeding program became ill presenting respiratory symptoms
(dyspnea, prostration, hyporexia and weight loss). The duck received
prophylactic antibiotic treatment (i.e., Enrofloxacin – Chemitril,
Chemitec – 15mg/kg, IM, q. 12h), with unsuccessful results. The animal
died presenting incoordination and opisthotonos, less than 24 hours
after the first clinical signs.
