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.
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.

The starter-phase duration for broiler breeders can affect their reproductive performance later, including development, fertility and hatchability, according to a study led by Edgar O. Oviedo-Rondón, DVM, MSc, PhD, Dipl. ACPV, North Carolina State University.
Researchers at North Carolina State University evaluated the effects of housing systems and genetic strains on broiler mobility in slow-growing strains vs fast-growing strains in both indoor and outdoor environments.

Consumer interest in poultry welfare has led to the expansion of unconventional poultry-rearing systems, such as silvopasture. Justin Lowery, MS, and a team of researchers from North Carolina State University conducted a broiler research trial comparing the impact of conventional and silvopasture production systems on the cecal microbiota of slow- and fast-growing broilers.
Cases from an outbreak of aMPV among broiler flocks in Mississippi are mostly coming with secondary infections, which can exacerbate disease severity. A research team led by Autumn Gregg, DVM, a poultry resident at Mississippi State University, investigated the infections appearing in the outbreak.
HPAI is a significant threat to the poultry industry, and vaccination alone is not enough to combat this virus, said David Swayne, DVM, PhD, DACVP, a former USDA scientist who has spent more than 30 years studying this disease. Swayne discussed HPAI vaccination programs, addressing four misconceptions about the vaccines.
The One Health approach, which encompasses human, animal and environmental health, is well-suited to address a disease issue such as HPAI, according to Meghan Davis, DVM, PhD, associate professor at John Hopkins Bloomberg School of Public Health and Engineering.

Gut health is often discussed in poultry production. But according to immunologist Michael Kogut, PhD, lead research microbiologist at the USDA-ARS, College Station, Texas, the term is really about gut homeostasis, which enables birds to maximize performance and reach their full potential.
