Vaccines are essential tools for managing diseases in poultry and ensuring flock welfare. Taking shortcuts with them is never a good idea, however, and there’s plenty of research to prove it. In the second of a two-part series, Bill Stanley, DVM, and Isabel Gimeno, DVM, PhD, talked about their experiences managing vaccines and ensuring optimum performance.
Incubation lighting has a limited impact on fear and stress responses in broilers, according to research presented by Angela Perretti, University of Arkansas poultry science graduate student, at the 2024 Poultry Science Association annual meeting.
In a recent Poultry Science publication, researchers in Egypt and Saudi Arabia reported that prebiotic and probiotic supplementation in flocks vaccinated for coccidiosis did not alter vaccine effectiveness or improve short-term, vaccine-induced declines in growth performance.
A deep dive into Eimeria research reveals a strong inter-relationship between coccidiosis and secondary infections, such as necrotic enteritis, that poses formidable disease control challenges in poultry.
A novel probiotic has been developed as a direct-fed microbial in both poultry and swine feed to improve gut health and weight-gain efficiency, according to the University of Arkansas.
Immunosuppression is a costly yet often misunderstood problem in the poultry industry. But what exactly is immunosuppression, and how can it be detected, diagnosed and measured? In the first of a two-part series, Isabel Gimeno, DVM, PhD, and Bill Stanley, DVM, share their expertise on this topic.
Stocking density is a key determinant of profits from a broiler operation as revenues per unit of space increase with increasing stocking density. However, overcrowding due to high stocking density can lead to negative behavior and welfare consequences.
Meeting tougher demands by the USDA’s FSIS to control Salmonella doesn’t warrant reinventing the wheel, according to Chuck Hofacre, DVM, PhD, president of the Southern Poultry Research Group, Inc.

Reducing the use of phosphate in feed can increase the security of raw material supply, cut costs and reduce farming’s environmental impact. But can this be done effectively without compromising bird health and welfare?
The pre-slaughter phase for broiler chickens is a period that contains many stressors and risks for animal welfare. Understanding the factors that can lead to negative welfare outcomes is important to make improvements in broiler chicken welfare during the pre-slaughter phase.
Molecular biology is a powerful tool the poultry industry can use to better understand and ultimately control avian coccidiosis. In a presentation at the 2024 PSA meeting, Mark Jenkins, PhD, discussed the usefulness of molecular biology and improved vaccination strategies to control coccidiosis.
