Importance and basic aspects of chicken's IN-OOO vaccination

Introduction

 

Nowadays, In-OVO vaccination is the most commonly used and used vaccination method in the poultry industry. This method uses most of the world's poultry farms (for example, 96% of the US-based poultry uses an in-OVO vaccination), as it has been shown by many pneumonia that the advantage of this method is compared to other vaccination methods.

 

These are the advantages:

 

  • Early immunity- 2-3 days prior to vacation, vaccine is introduced into embryos where immune reactions occur and we take 1 day chicken, which has an early immune response to specific diseases.
  • Decrease stress – No more than 1 day spray on vaccination in the neck is vaccinated, which is a significant problem prevention. Since the newly-cut chickens are sensitive to any stress.
  • Profitability – The In-OVO vaccination machine is an automatic mechanism that requires much lesser cameras than other vaccination methods. In addition, the injection dose is less than every 1 kg (0,05 ml or 0.1 ml)
  • Reduce the impact of human factors – We do not see any of the chicks that are incorrectly discharged by the operator during the injection in the neck. It is not excluded that the chicken is not vaccinated because in-OVO vaccination is a systematic process that is undergoing mechanical algorithm. It is also worth noting that the human contact with chickens is a mechanical pollutant.
  • A more healthy chicken - A 1 day chickpea is no longer hazardous by vaccination process and goes directly to the poultry where the food and water is obtained early. Also, the In-OVO vaccination device is the needle for all injections, which is the prevention of bacterial contamination.

 

 

In-OVO Peculiarities of vaccination

 

The use of In-OVO vaccination apparatus is a complex process involving knowledge of the embryonic development process or the date of incubation and which vaccine injection should be administered. Optimum time In-OVO vaccination is 17.5-19.2 days of embryo development (chalk is under the right wing, and the yellow park begins to transplant the baby to the abdominal cavity), and the relevant injections are: amniotic hollow and embryo's body. Therefore, post-vaccine reactions are not observed, and the chicken cutting is the maximum. In early or late vaccinated chicks, egg injection in other layers leads to swings and immune reactions.

 

 

Conclusion

 

In recent years, the embryo in-OVO injection has become an important vaccination method used to prevent infectious diseases. The use of new generation vaccines (Transmune IBD, Vectormune ND, VAXXITEK HVT + IBD & hellip;) is recommended by the In-OVO vaccination method to avoid stress in 1-day chickens, based on the above-mentioned advantages as recommended by poultry vaccines manufacturers. And to promote early immunity.
