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.

Behind every successful poultry operation is a dependable vaccine supply chain. But producing vaccines is no small feat — it requires precision, foresight and the ability to adapt to biological and regulatory challenges. Daniel Hamby, senior associate director of manufacturing science and technology at Boehringer Ingelheim, gives a behind-the-scenes look at vaccine production and explains what it takes to deliver consistent, high-quality products to the industry.

Currently, 38.7% of laying hen housing systems in the United States are cage-free and this transition continues to increase. However, little attention has been given to pullet housing systems. In this article, Richard Blatchford, PhD, University of California, Davis, provides important considerations for pullet management.

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.

Feed is a vital part of the poultry industry, representing around 60-70% of the total costs. However, even the best feed formulation cannot deliver results if the birds cannot access it readily. Anusha Gautam and Bethany Baker-Cook, PhD, Auburn University, discuss the right type of feeders to select for each of the production phases, appropriate feeder spacing, proper feeder height, and the overall feeder arrangement.

A joint research study conducted by the USDA and North Carolina State University researchers demonstrated that the type of housing system used for laying hens can influence levels of human pathogenic Salmonella in their organs.

Conducting in-lay boosting of adult, organic, free-range laying hens with a Pasteurella multocida vaccine protected against fowl cholera with minimal impacts on production, according to a study conducted by Luke Trimble, DVM, Wilson Vet Co.
