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.
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.
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.
Eric Shepherd, DVM, Zoetis, takes a look at potential IBD vaccination programs that may disrupt field virus pressure, restore disease control and support overall flock health.
The USDA Center for Veterinary Biologics has granted Huvepharma approval for the manufacturing and sale of a new broiler-breeder coccidiosis vaccine, Advent P, which contains Eimeria necatrix and E. brunetti.
Breeding for increased appetites and fast growth has resulted in meatier birds. But these heavier birds experience health complications and decreased reproduction. Feed restrictions are used to maintain the lower bodyweight required for broiler breeders. University of Arkansas graduate student Allison Weaver is researching how feed restrictions affect bird welfare.

Avian metapneumovirus has not been detected in the US since the 1990s. So, it was a surprise in 2023 when cases began surfacing in Virginia, West Virginia and North Carolina. By January 31, 2024, the Georgia Poultry Laboratory Network received its first suspect case. Here’s what they did.

A precision poultry-feeding system developed by University of Alberta scientists has the potential to bring improved fertility, better flock uniformity and significant savings for broiler breeder producers.
Europeans have battled avian metapneumovirus (aMPV) since the 1980s. Today, live and inactivated vaccines keep aMPV under control in Europe and most of the world except in the US, according to Aris Malo, DVM, Royal Dutch Veterinary Association.
