Novamune® Stops the Gumboro cycle

The bursa colonization by SyZA-26 prevents the infection and shedding of the field virus, therefore STOPPING The Gumboro Cycle in the pullet house.
For many years, layer producers have been vaccinating their pullets against Gumboro Disease through drinking water and, most recently, rHVT IBD. Due to inadequate vaccine take or inability to replicate in the BF, these types of vaccines cannot prevent the replication of field virus in this primary lymphoid organ, consequently preventing the shedding of the field virus to the environment.

What is Novamune®?

The best option to control IBD is to use a live attenuated IBD vaccine, which is capable of reaching the bursa and generate a high level of protection against various types of IBD viruses and effectively preventing shedding.
The best option to control IBD is to use a live attenuated IBD vaccine, which is capable of reaching the bursa and generate a high level of protection against various types of IBD viruses and effectively preventing shedding. This way, the virus pressure decreases cycle after cycle, and the likelihood of the emergence of virulent variant IBDV can be strongly reduced.

Gumboro control in layers

The Gumboro control in pullets includes both protection and prevention.
The Gumboro control in pullets includes both protection and prevention. Therefore the objective of Gumboro disease vaccination must be to ensure continuous protection against infection with IBD virus, prevent the build-up of higher virus pressure cycle after cycle, and reduce the risk of IBD virus mutation towards a more virulent strain.

Gumboro disease in layers

"Gumboro Disease" is caused by the IBD virus that replicates and damages the bursa of Fabricius of young pullets leading to high mortality, poor performance.
Infectious bursal disease (IBD) or "Gumboro Disease" is caused by the IBD virus that replicates and damages the bursa of Fabricius of young pullets leading to high mortality, susceptibility to other diseases and poor performance.

Don't let immunosuppressive diseases compromise broiler performance

Disease experts discuss the importance of managing immunosuppression in broiler flocks. Sponsored by Poultry Health Today.
Immunosuppressive diseases such as infectious bursal disease virus, Marek's and reovirus can compromise a bird's ability to fight off secondary infections. Keeping them in check becomes even more critical as poultry companies reduce or eliminate antibiotics. Poultry Health Today talked with disease experts about the importance of managing immunosuppression in broiler flocks.

Why live ND vaccines are NOT good enough for low ND challenge countries?

Novel ND vaccines permit massive and uniform vaccine administration at the hatchery to induce early and lifelong lasting immunity with minimal additional field interventions have been achieved.
In low ND challenge countries, industrial chickens are often facing the uncontrolled circulation of lentogenic (vaccine) strains, especially in high densely populated poultry areas. As a result, they may show subtle to overt respiratory signs, because of the inflammation of the trachea. It may worsen in case of suboptimal husbandry conditions. As a result, flock uniformity will decrease, and secondary opportunistic respiratory infections may arise with the need to apply antibiotic medication. Ultimately, slaughterhouse condemnations may increase due to excessive airsacculitis.
