Methods and compositions for increasing the hatchability of hatchery eggs

摘要

Provided is a method for the hatching of hatchery eggs including: (a) treating the egg shell surface with a coating composition including a coating agent, to form a coating on the surface of the egg's shell; and (b) incubating the egg under conditions to cause hatching to occur; wherein the yield of hatching of the hatchery eggs is improved as compared to control eggs not treated as defined in (a). Further provided is a composition for the treating of hatchery eggs prior to incubation, where the composition includes a coating agent, and where the composition improves the hatching yield of the hatchery eggs.

主权项

1. A method for improving hatching yield of hatchery eggs, comprising:
applying a coating composition to a surface of a shell of at least one hatchery egg,
the coating composition comprising a coating agent and a liquid vehicle,
the coating agent being present in a concentration of from 0.01 to 8% w/w based on the total weight of the coating composition and being selected from the group consisting of a polymer, a polysaccharide, a lipid, a protein, a natural wax, a natural resin, a hydrocarbon and a latex, and mixtures thereof; evaporating the liquid vehicle from the coating composition to form a porous solid or semi-solid coating over the surface of the shell; and incubating the at least one hatchery egg under conditions sufficient to cause hatching,
wherein the hatching yield of the at least one hatchery egg subjected to the coating composition is greater than that the hatching yield of other hatchery eggs that were not subjected to the coating composition.
