“Turkeys will pick up the oocysts from the feces in the bedding,” Pollock said. “Between day 0 and day 60, we want to have a coccidiostat or a vaccine. After that, they stop being susceptible. Coccidiosis parasites endanger turkey gut health by penetrating and replicating in GI epithelial...

Many studies show that ambient temperatures outside the normal range can negatively affect the health and performance of chickens, but there is little comparable research in turkey poults. Moreover, most chicken studies focus on extreme heat stress -- for example, 7-10°C (about 13-18°F) above an...

Poultry water systems can be a vector for both avian and human pathogenic bacteria. To sanitize, producers often use bleach -- an economical, chlorine-based, solution of sodium hypochlorite (8.25% NaOCl). New research evaluates current water sanitation practices and their effect on Salmonella,...

With previous outbreaks of HPAI in 2015 and 2022, quickly and efficiently depopulating flocks was crucial to preventing the spread. However, preferred methods (foam, containerizing gassing, and mechanical) are not always an option when quick action is required. This recent study from The...

The majority of today’s broiler breeders are highly concentrated. With this comes increased risk of disease outbreaks and corresponding responses (such as depopulating flocks) to combat disease. This study from The Journal of Applied Poultry Research shows that postmolt vaccination can...
