It is marked by cough, dyspnea, anorexia and constipation.
Bovine respiratory disease (BRD) is the most common and economically devastating infectious disease affecting beef cattle in the world. [1] It is a complex, bacterial or viral infection that causes pneumonia in calves which can be fatal.

The Muscovy duck (Cairina moschata) is a duck native to the Americas, from the Rio Grande Valley of Texas and Mexico south to Argentina and Uruguay.The species has been domesticated, and feral Muscovy ducks can be found locally in New Zealand, Australia, the United States, and in Central and Eastern Europe.
Derzsy's disease is caused by Anseriform dependoparvovirus 1, in the Parvoviridae family. It affects geese and Muscovy ducks . The virus is shed in the faeces and thus transmission is horizontal, via the direct faecal-oral route and also indirectly via fomites .
The Muscovy is commonly reared for meat. [7]: 78 In commercial production, it is often crossed with a mallard-derived domestic duck such as the Rouen or Pekin to produce the hybrid known as a mulard. [7]: 97 These hatch in about four weeks and grow rapidly like a mallard-type duck, but to about the size and weight of the Muscovy.
The latest analysis revealed that muscovy ducks in the sample were also fed maize. Based on these data, researchers say there was intentional feeding of these animals occurred in this region as ...
