Vaccines For Broilers

Vaccination is an effective means to prevent and/or reduce the adverse effects of specific diseases that can cause problems in a poultry flock. Approved vaccines are allowed under the USDA organic standards. Always check with your certification agency before administering any product to your livestock

Vaccination programs for broilers is an essential tool for disease prevention, particularly for viral diseases, in poultry farming.  It causes an immune response in birds to protect them from the field infection. Vaccines usually contain the attenuated pathogen or at low concentrations to cause a mild infection, or antigenic components of the microorganism.

Description

For the modern poultry industry vaccination plays a key role in the prevention of infectious diseases. Vaccination of broiler breeders is especially important as this protects not only vaccinated birds (the breeders) but also their progeny (broilers). There are two main types of vaccines available for the broiler breeders (BB) – live and killed.

Live vaccines contain live microorganisms, viruses (like Newcastle Disease virus), bacteria (like Salmonella typhimurium) or parasites (like coccidia – E maxima etc.). Fairly recently, new types of live vaccine were introduced – recombinant vaccines. Recombinant vaccines currently available on the market contain a live virus as a carrier.  In the genes of this virus a portion of the genes of another virus have been inserted (for example, Herpes Virus of Turkeys, a virus that is commonly used to protect chickens against Marek’s Disease carries a portion of the genes of Infectious Bursal Disease virus). Vaccination with this type of vaccine protects against both diseases. The biggest advantage of live vaccines is that they can be applied by mass application techniques such as spray or in the drinking water. Unfortunately, live vaccines can be easily damaged in the process of transportation, storage or application (by high temperatures, sunlight or disinfectants).

Killed vaccines contain inactivated (dead) viruses or bacteria in (most often) an oil emulsion. Killed vaccines must be injected to each bird in the flock but provide long lasting immunity which is important for long living birds like broiler breeders. This is especially true after “priming” with live vaccines (if live vaccine of the same type is given before the killed). Most of the killed vaccines are commercial products manufactured and licensed for a certain country or region. A unique type of killed vaccine is the “autogenous vaccine”. When a pathogen (virus or bacteria) is affecting one or a group of flocks and no commercial product is available, autogenous vaccine is made to prevent those diseases. They are made in smaller batches under supervision of a veterinarian.
