Crowds gathered at the Zoetis exhibit at the 2015 International Production and Processing Expo to help the company celebrate another milestone: 230 billion eggs vaccinated worldwide with Embrex Biodevices. Chris Williams, one of the machine’s early developers, talked with Poultry Health Today about the evolution of this game-changing technology and its impact on the global poultry industry.
More than 20 billion eggs are injected each year using Embrex® in ovo vaccine technology, a tool that has enabled producers to streamline operations, save costs and provide protection against viruses like Marek’s disease from hatch.
A steady shift to in ovo vaccination in the Asia-Pacific region is encouraging many hatcheries there to improve practices and management in preparation for the switch.
Antibiotic-free poultry production is creating ethical conflicts for veterinarians while raising questions about sustainability, animal welfare and the industry’s ability to feed a growing population, says David French, DVM, of Sanderson Farms.
John Glisson, DVM — professor emeritus at the University of Georgia and well-known respiratory disease specialist — talks about the ups and downs on infectious laryngotracheitis (ILT) in poultry and the best ways to manage this unpredictable disease.
