Despite the industry’s best efforts to control colibacillosis in layers, broilers and breeders, the bacterial disease caused by avian pathogenic Escherichia coli (APEC) continues to challenge producers and researchers.
Most poultry producers today use vaccines to help manage coccidiosis. Live coccidial vaccines are designed to uniformly infect birds with a controlled number of Eimeria oocysts to stimulate a protective immune response, but not all vaccines are the same.
Feeding broilers a high dose of a bacterial 6-phytase alongside a xylanase-glucanase enzyme combination resulted in performance improvements and cost savings, in a field study.
Turkeys are seasonal breeders, meaning exposure to a long-day photoperiod triggers the reproductive response. The challenge is that the photoreceptors are deep within the brain. The light must therefore penetrate the skull and brain tissue to elicit a response.
A multistate salmonella outbreak in the US due to the consumption of contaminated turkey products spurred a joint effort between the Centers for Disease Control and the turkey industry to identify an untraditional serotype of Salmonella, S. enterica serotype Reading (S. Reading).
Adding fishmeal into the diets of broiler breeder roosters could improve egg hatchability, North Carolina State University research suggests.
Continuous lighting is commonplace in commercial broiler houses, but is that what’s best for the birds?
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.
Utilizing postbiotic feed additives in poultry diets could help producers find customized solutions to challenges facing the poultry industry, according to an expert in poultry gut health.

The National Chicken Council recently developed a Q&A on vaccines to help veterinarians, producers and others involved in live production educate their families, friends and communities about their usage in poultry production.
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.
