Abstract
The methods and compositions provide for increasing the productivity of quality hatchery eggs by applying a coating to the outer surface of the eggs. The liquid coating compositions and methods described herein facilitate mechanical enforcement of the shell, protection against adverse environmental conditions, prevention of contamination, differentiation of egg parentage and allow for appropriate gas exchange during storage or shipping periods.
Claims20
A method for increasing the productivity of fertilized avian eggs comprising
- a) treating the egg's outer surface with a liquid coating composition comprising:
- i. an aqueous solvent
- ii. a film-forming coating agent;
- and
- iii. one or more surfactants;
- b) allowing said liquid coating composition to form a coating on the egg,
- c) incubating the egg under conditions to cause hatching to occur;
- wherein the productivity of said avian eggs is increased as compared to control eggs not treated as defined in (a) to (b).
A liquid coating composition for coating the outer surface of an egg comprising:
- a) an aqueous solvent;
- b) a film-forming coating agent;
- and
- c) one or more surfactants;
- wherein said liquid coating composition is readily removable from said outer surface of an egg.
