In the United States, the majority of laying hens are housed in conventional cages. However, there has been a shift towards cage-free systems. Cage-free systems can benefit laying hen welfare. Birds have opportunities to perform a full range of species-specific behaviors, including foraging, dustbathing, perching, and walking, which are restricted in conventional cages.
Brazilian researchers conducted a two-part epidemiological study to determine the serological, molecular and pathological status of ILT in two regions. The team described their findings and what they mean for poultry producers.
The International Poultry Welfare Alliance brings together expertise from across the value chain to develop Key Welfare Indicator Reference Guides for broilers, turkeys and layers, which align measurements and communications of welfare outcomes.
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.
In December 2025, US Poultry & Egg Association (USPOULTRY) released an updated report quantifying the US poultry industry’s on-farm antibiotic use.
Research from Isabel Gimeno, PhD, DVM, North Carolina State University, is adding to the growing support of the role of in ovo vaccination in bolstering early immunity against disease risks both broilers and layers face in the field.
Field data from a large commercial layer enterprise confirm that Cargill’s Biostrong™ C-Protect — a postbiotic/phytogenic blend — supports improved livability in layers in the face of avian pathogenic Escherichia coli (APEC).
By researching the impact of ectoparasite infestations in laying hens through a behavioral lens, Purdue University doctoral student Haley Sutherland aims to identify characteristics or heritable traits that help hens resist mite infestations.
Research from Ceva Animal Health suggests that eggshell rinses may be a viable, accessible way to detect infectious bronchitis virus infection in layer flocks experiencing egg quality abnormalities.

Salmonella exposure to consumers from eggs has been a decades-long concern. Richard Gast, poultry research microbiologist at USDA’s US National Poultry Research Center in Athens, Georgia, has developed two research projects to gain more perspective on Salmonella Enteritidis in cage-free layer housing.
US poultry producers have a new, FDA-approved weapon in the fight against Northern fowl mite (NFM) with Exzolt™ (fluralaner oral solution), a pioneering treatment from Merck Animal Health.
