Fowl cholera is a bacterial disease of poultry that commonly affects chickens around 15 weeks of age and older, but it can impact birds as young as 6 weeks, cautions Charlie Broussard, DVM, Merck Animal Health.
Merck Animal Health has introduced Innovax®-ILT-IBD, a vaccine that provides combined protection and immunization against Marek’s disease (MD), infectious laryngotracheitis (ILT) and infectious bursal disease (IBD) in a single injection.
Vaccination is key to managing fowl cholera in poultry. For a program to be successful, however, it’s critical to train vaccination crews to monitor vaccine “takes” or major cutaneous reactions within a flock — no easy task with today’s employee shortages and rotating vaccination crews.
Since it was first isolated in broiler flocks on the Delmarva Peninsula, the latest mutation of infectious bronchitis virus (IBV), DMV/1639, has spread through the eastern seaboard of the US and west toward Mississippi and Texas.
There are many pests and pathogens to monitor on poultry farms, but bed bugs typically aren’t top of mind. Nevertheless, bed bug infestations have been resurfacing in US poultry farms. Does that present a health, performance or welfare problem for flocks?
Developing a thorough vaccination strategy for fowl cholera — one that includes selecting the right vaccine strain for the field challenge that the birds are facing and proper vaccine administration — is critical when managing this bacterial disease.
Even with the best flock-management and vaccination protocols, fowl cholera can occasionally find a crack in the system. Chronic, low-grade cholera problems can materialize, or occasional breaks in breeder flocks can suddenly appear.
