Egg injection method, apparatus and carrier solution for improving hatchability and disease control
First Claim
1. A method for increasing the hatchability of avian hatchery eggs and for improving the process of automatic injection of said eggs in the control of disease of viral, bacterial, and microbial types, wherein said eggs are injected with beneficial formulations of vaccines, vitamins, nutrients, and trace minerals, said method comprising forming a mixture of said formulations with an injectable disinfectant contamination control carrier solution effective in preventing contaminants from entering said egg during the injection thereof, applying said solution to an intended injection site of the shell of said egg prior to injection of said mixture, and injecting said mixture directly and invasively into developing embryos of said egg during the incubation period thereof, or into the amniotic fluid supporting said embryos prior to setting said eggs into an incubator.

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.

17. An egg injection machine with an injectant delivery system which utilizes the disinfectant properties of a contamination-control injectant carrier solution to provide sterilization of the injectant delivery system and localized egg injection site, and wherein the egg injection machine delivers contamination-free beneficial injectables into the hatchery egg;
- said machine comprising;
(a) means for positioning a plurality of eggs arranged in a tray directly coincident with a corresponding plurality of hollow injection needles; (b) means for advancing said needles into said eggs; (c) means for pulsing a jet of disinfectant solution toward said eggs, thereby sterile-washing elements of said machine and eggs at the localized injection site prior to penetration of said needles into said eggs; (d) means for producing pulses of injectant carrier solution through said needles; (e) timing means for generating timed production of said pulses of said disinfectant solution and said injectant solution in synchronism with said advancement of said needles; (f) means for decelerating said needles after the shells of said eggs have been pierced; and (g) means for withdrawing said needles from said eggs. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
- said machine comprising;
-
33. A method for increasing the hatchability and control of viral, bacterial, or microbial diseases in avian specie hatchery eggs comprising the steps of:
-
(a) preparing a formulation of beneficial injectable materials in an aqueous contamination control carrier solution, (b) placing a tray containing eggs into a tray holder assembly for alignment coincident with strokes of a plurality or hollow injection needles, (c) initiating a timed sequence of needle drive and pump energization which sterile-washes the egg shell and injectant delivery system and, at the end of said needle strokes, delivers through said needle into a corresponding egg a measured amount of beneficial formulation, and (d) retracting said needles from said eggs. - View Dependent Claims (34, 35, 36)

37. An injectable liquid for conveying nutrients and/or antibiotics by invasive injection directly into the embryo or amniotic fluid of a fertilized egg, said liquid including, a live-virus vaccine suspended in a carrier solution having disinfectant properties effective in preventing contaminants from entering said egg during the injection thereof, when applied to the intended injection site of the shell of said egg prior to injection, said carrier solution comprising a mixture in the range of 50%, to 80% ethanol, and a balance of water.
