For poultry companies, a successful infectious bronchitis vaccination program depends on more than choosing the right vaccine for the challenge at hand. According to Jose Linares, DVM, Ceva Animal Health, consistently high vaccine takes depend just as much on the quality of vaccine application.

In the third installment of Phibro Academy’s three-part webinar series, “Coccidiosis Tools and Strategies,” Greg Mathis, PhD, president of Southern Poultry Research, Inc., discusses anticoccidial sensitivity testing and how best to interpret results and apply them in the field.
Today’s cage-free laying systems provide extra vertical space for birds to be physically active, which can lead to variability in feed intake and body composition. If feed was restricted, would chickens change their activity levels, or would a hypothalamic response be triggered to increase feed intake?
Research from the University of Arkansas suggests that giving turkey poults feed cues with green, moisture-rich feed attractants may help them find feed sooner, forage earlier and gain more weight during the first 10 days after placement.

An innovation taking the broiler/breeder industry by storm is Comfort Nest™, a mechanical egg-laying system from VAL-CO that more than doubles the nest size to accommodate high-yield broiler-strain hens.
Can laser enrichment improve broiler health and marketability? Kayla Elmore, a graduate student at Iowa State University, conducted a study to investigate this question, following up on two previous studies that reported increased activity among broilers exposed to lasers.
Hatchery day-of-age vaccination has been a cornerstone of broiler health for decades, but new research is shedding light on the mechanisms that help it protect chicks despite the immaturity of their immune systems. The findings are significant because it is widely used throughout the poultry industry, yet relatively little is known about how newly hatched chicks develop protection following vaccination.
Broiler breeder fertility has been declining over the past decade, raising concerns about both productivity and the long-term sustainability of the industry. Marcela Quino, a graduate student at Auburn University, examined how time of day, rooster competition and behavior influence mating success and fertility during the early production period.
When faced with these emerging IBDV variant strains, it’s important to provide every chick the strongest possible immune start while keeping pace with a changing virus. Kalen Cookson, DVM, MAM, DAPVC, director of clinical research, Zoetis, provides vaccination strategies for poultry vets to consider.
