Decreased incidence of condemnation

Vaccination in poultry production is vital to protect the birds against the main viral diseases: Marek’s disease, infectious bursal disease or Gumboro disease, infectious bronchitis, Newcastle disease, avian influenza, etc, as well as bacterial diseases: colibacillosis, mycoplasma infections, etc and also coccidiosis. If we refer more specifically to broiler chicken meat production worldwide, the implemented vaccination programs aim at controlling these diseases, and help improve liveability for the most highly impacting diseases such as Newcastle disease or highly pathogenic avian influenza. They also help prevent the consequences of poor control of less acute forms of these diseases, such as: condemnation of broilers at the slaughterhouse, increased cost of medication and use of antibiotics, negative impact on overall growing performances, decreased meat production and overall economic value. Sub-acute forms of the disease may also have a strong impact on productivity, such as in the case of subclinical necrotic enteritis, that was estimated as decreasing the value of 20,000 chickens by about US$878 for 4.63lb birds, and up to The cost benefits of vaccination in poultry production
