Broilers do not spread evenly across their environment. Some may cluster near a wall, equipment line, or other boundary, while other areas appear relatively unoccupied. Shawna Weimer, PhD, University of Arkansas, explores the behavior of wall hugging and what it means to broiler production.
When vaccine decisions are grounded in sound diagnostics and veterinary guidance, but flock performance does not improve as expected, the vaccine itself may not be the problem. It may be time to review how the product was stored, prepared and applied. Abigail Graham, DVM, MAM, DACPV, Zoetis, explains how.
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.
