ABSTRACT:
An egg injection machine, beneficial injectable formulations for increasing the hatchability of avian hatchery eggs, and an improved method for the control of contamination in the injection process are provided. A novel ethanol-based contamination control carrier solution allows beneficial vaccines, vitamins, nutrients, and trace minerals to be injected into fertile eggs without risk of contamination of the eggs by machine, solution, or egg-to-egg cross-contamination by the injection needle. The invention is useful in both the chicken and turkey hatchery industry for egg injections prior to incubator setting or during transfer to hatch bins. Hatch improvements of +2.29 percent to +5.33 percent are shown for varying conditions. A method for facilitating the injections of virus vaccines is disclosed.
