Healthier poultry starts with precise immunization. Only the Embrex® Inovoject® System, a BioDevice from Zoetis, provides the highest level of injection site accuracy to help ensure your chicks are protected from disease challenges.*,1,2

Precise in ovo vaccination with Embrex technology provides benefits to bird healthwhen compared with competitor single-needle in ovo vaccination and subcutaneous vaccine administration.2


The Inovoject System does more than just deliver vaccine accurately and effectively. It can also help make your entire operation more efficient.

    • Optimum sanitation – A well-synchronized disinfection system in conjunction with a dual needle which separates the shell surface contaminants from the injection needle allows for optimum sanitation after each injection.
    • Lower potential for human error – Automated process not only reduces the margin for human error, it can also lead to labor savings and more accurate results.
    • Reduced bird stress – Minimize the need for subcutaneous vaccinations at chick processing, allowing birds to be transported to the farm faster and into the ideal grow-out environment.
    • Vaccine savings – Identifies infertile and early dead eggs, helping to ensure only viable eggs are vaccinated. The result: it cuts in ovo vaccine doses by an average of 10%,3 which helps contain costs and promote value.
