Multi-strain bacterin vaccine demonstrates broad protection against spotty liver disease

Recently, Campylobacter hepaticus was identified as the causative agent for chicken spotty liver disease (SLD), an illness which manifests as acute infectious hepatitis and causes a significant drop in egg production and high mortality in layer chickens. Researchers from Iowa State University, led by Orhan Sahin, DVM, PhD, are studying Campylobacter bacterins in the control of SLD.

New focus on the mental strain of humane endings in animal-health work

Euthanizing animals can be a psychologically traumatic experience for veterinarians — and mass-depopulation events such as those associated with highly pathogenic avian influenza (HPAI) are putting the issue front of mind.  

Shane: Vaccination needed in face of airborne HPAI threat

sspiegel0120@gmail.com on January 25, 2024

Evidence that airborne spread of highly pathogenic avian influenza (HPAI) is possible near flocks of wild birds underlines that even extreme biosecurity won’t completely protect egg-production flocks, according to an industry commentator.

Researchers exploring sale of uncontaminated table eggs from HPAI-positive farms

Common causes of mortality in cage-free egg production systems

While some mortality is expected in all layer flocks, regardless of the housing type or breed, the rate and causes can vary depending on the production system. Cage-free systems may not inherently have higher mortality than cages and experience in managing birds in cage-free systems plays a big role in maintaining low mortality.
