TOOLBOX, Issue 36: An interview with Manuel Da Costa, DVM, PhD, Associate Director, Outcomes Research, Zoetis
Consistent surveillance and analysis of infectious bronchitis virus (IBV) at poultry production facilities can guard against “overvaccination” — where too much vaccine virus in the environment causes a rolling reaction in flocks.
E.coli may be largely responsible for focal duodenel necrosis (FDN) in layer chickens, according to research presented at the 2022 International Poultry Scientific Forum (IPSF).
A higher risk of bacterial challenges in cage-free egg production means a live-vaccination program against Escherichia coli is a “must-have minimum” for flocks reared in alternative systems.
