Claims
- 1. A method of non-invasively infusing a fertilized avian egg with oxygen such that the structural integrity of the shell of the egg is not compromised, said method comprising the step of: subjecting the external surface of the eggshell to the oxygen under positive pressure from a pressure source having a total positive pressure greater than ambient total pressure, said pressure being from about 5 PSI to about 32 PSI, for about 45 seconds to about 24 hours whereby the hatch rate of the oxygen-infused egg is greater than that of a fertilized egg not so infused with oxygen, wherein said oxygen is from a source selected from the group consisting of pressurized air, pressurized gaseous O.sub.2 and pressurized gaseous O.sub.3.
- 2. The method of claim 1 wherein substantially all of the external surface of the eggshell is subjected to the condition of positive pressure.
- 3. The method of claim 1 further comprising the step of: subjecting the extensional surface of the eggshell to vacuum of from about 28.5 inches Hg to about 29.8 inches Hg for about 40 seconds to about 10 minutes prior to subjecting the external surface of the eggshell to said positive pressure.
- 4. A method of non-invasively infusing a fertilized avian egg with oxygen such that the structural integrity of the shell of the egg is not compromised, said method comprising the steps of: subjecting the external surface of the eggshell to vacuum of from about 28.5 inches Hg to about 29.8 inches Hg for about 40 seconds to about 10 minutes, and, subjecting the external surface of the eggshell to the oxygen under positive pressure from a pressure source having a positive pressure greater than ambient pressure, said pressure being from about 5 PSI to about 32 PSI, for about 45 seconds to about 24 hours whereby the hatch rate of the oxygen-infused fertilized egg is greater than that of a fertilized egg not so infused with oxygen, wherein said oxygen is from a source selected from the group consisting of pressurized air, pressurized gaseous O.sub.2, and pressurized gaseous O.sub.3.
- 5. The method of claim 4 wherein substantially all of the external surface of the eggshell is subjected to the condition of positive pressure.
