An in ovo jet injection apparatus and related methods for treating live eggs. The jet injection apparatus includes one or more jet injection delivery devices configured to deliver one or more treatment substances to predetermined areas of eggs using a high pressure stream of the treatment substance(s). Multiple treatment substances can be delivered so that they are spatially and/or temporally separate. The devices and methods of the invention enable the effective use of a plurality of treatment substances, including those that are effective when used alone but can be noxious if mixed. The methods and apparatus for the jet injection of substances into embryonic chicks reduce the risk of mechanical injury to the developing birds that would be caused by injection needles. The methods and apparatus of the invention can also reduce the introduction of an infection into the chicks.

L'invention concerne un dispositif de jet par injection in ovo et des procédés connexes de traitement des oeufs d'oiseaux. Le dispositif comprend un ou plusieurs appareils d'injection permettant de fournir une ou plusieurs substances de traitement dans des parties préétablies des oeufs, sous flux haute pression. On peut ainsi délivrer plusieurs substances en séparation spatiale et/ou temporelle, et assurer l'utilisation efficace de ces substances, y compris les substances efficaces en utilisation séparée mais nocives en utilisation mélangée. L'injection dans des oeufs embryonnés réduit les risques de blessure mécanique sur les poussins naissants, contrairement à une injection par seringue. On peut enfin réduire de la sorte les risques d'infections.
