Research sheds light on how chicks develop immunity after DOA vaccination

Hatchery day-of-age vaccination has been a cornerstone of broiler health for decades, but new research is shedding light on the mechanisms that help it protect chicks despite the immaturity of their immune systems. The findings are significant because it is widely used throughout the poultry industry, yet relatively little is known about how newly hatched chicks develop protection following vaccination.

Chronic stress decreases neurogenesis in poultry

Poultry researchers use ‘affective valence’ — a positive or negative emotional response — as a measure of animal welfare. Tom Smulders, PhD, an evolutionary neurobiology researcher from Newcastle University, has studied whether hippocampal neurogenesis can be a marker of affective valence in poultry.

Changing IBDV landscape warrants vaccine programming reset

When faced with these emerging IBDV variant strains, it’s important to provide every chick the strongest possible immune start while keeping pace with a changing virus. Kalen Cookson, DVM, MAM, DAPVC, director of clinical research, Zoetis, provides vaccination strategies for poultry vets to consider.

Kogut: What ‘gut health’ really means for broiler performance

Gut health is often discussed in poultry production. But according to immunologist Michael Kogut, PhD, lead research microbiologist at the USDA-ARS, College Station, Texas, the term is really about gut homeostasis, which enables birds to maximize performance and reach their full potential.
