Resetting the field challenge with a strategic IBD vaccination approach
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.
USDA has authorized Boehringer Ingelheim to import two of the company’s live-virus vaccines for emergency use to help protect US poultry against avian metapneumovirus (aMPV) — a highly contagious respiratory viral infection that can result in severe respiratory symptoms and increased mortality in poultry.
More than 6 million birds have been vaccinated against avian metapneumovirus (aMPV) type B since the September rollout of the first experimental autogenous vaccine produced in the US, according to Ivan Alvarado, PhD, associate director, scientific marketing affairs, Merck Animal Health.
In the last 2 decades, strides in poultry nutrition helped build profitability for poultry producers in the US and around the world. Average US feed-conversion rates (FCR) have improved by 23 points (0.23) since 2000, according to Michael Kidd, PhD, professor in the Department of Poultry Science at the University of Arkansas.
Poultry genetics has evolved rapidly in the last 2 decades and continues to advance steadily, but research from Cargill Animal Nutrition suggests that birds’ diets need to be updated alongside genetic progress to maximize performance.
