Goslings and Muscovy ducklings that have waterfowl parvoviruses have severe morbidity and mortality, with mortality rates ranging from 10% to 80% and sometimes up to 95%. The majority of isolated Goose Parvovirus (GPV) and Muscovy Duck Parvovirus (MDPV) strains are harmful to young animals and highly virulent. Anorexia, prostration, watery diarrhoea, gastrointestinal symptoms, and mortality are the hallmarks of this illness. Both infected older birds and young birds that have survived exhibit growth retardation and degenerative skeletal muscle myopathy. The condition, also known as Derzsy's disease, has a significant financial impact on the care of ducks [1]. Additionally, in France, Hungary, Poland, and Taiwan, several unique GPV strains result in symptoms like small bills with projecting tongues and growth retardation in mule and Tsaiya ducks.
