Biosecurity in the Egg Industry
Biosecurity measures form an integral part of egg production in protecting hen wellbeing and food safety and assisting with the prevention of the introduction of infectious diseases to flocks.Biosecurity is about managing the risks of reduced productivity, profitability and long term financial viability of egg production businesses.
Salmonella control in layer chickens
Confidence in the ability to reduce any presence of Salmonella on shell eggs by the use of vaccine technology determined.
Vaccination and infectious bronchitis virus (IBV) challenge in mature laying hens
All pullets currently reared in Australia for egg production are vaccinated with live attenuated strains of infectious bronchitis virus (IBV).However, questions have been raised about possible negative effects of attenuated vaccines in adult layer birds.
The effect of Newcastle disease vaccination with strain V4 on the course of infections with the Peat
This study sought to deliver data from experiments on whether vaccination with V4 is effective against NDV, the Peats Ridge strain of the virus, and the serological response to infection with the Peats Ridge strain prior to vaccination. .
Optimising infectious bronchitis vaccination of laying hens for maximum egg shell quality
This study was designed to evaluate different vaccination protocols for infectious bronchitis virus in laying hens.Age at first vaccination, route of vaccine administration, regular revaccination during lay, and timing of revaccination in relation to an induced moult was investigated.
Enhancing mucosal immunity in chickens
Infection in chickens caused by microbial pathogens at the intestinal surface can be a challenge for the Australian poultry industry.However, there are a number of novel vaccination strategies which can enhance antibody production and reduce the incidence of infection and ultimately improve flock health and performance.
