Problems solved by technology

Because males and females are born at an approximate 50/50 sex ratio, approximately half of all avian born at such operations are thus lost and unproductive or provide diminished production.
For that matter, studies have shown that increased incubation temperature in very specific H&H stages (a series of normal stages in the development of the chick embryo as provided

Embodiment Construction

[0031]In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and / or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings.

[0032]The various systems and methods disclosed herein relate to controlling or influencing the sex of embryos in eggs in order to promote the development of embryos of a selected sex.

[0033]The systems and methods rely on the application of light having selected wavelengths to incubated eggs in order to influence the sex ratios of embryos in development within the eggs. The systems include an incubating device having an interior cavity in which lighting elements emitting ...

Abstract

The sex of embryos in eggs is influenced or controlled through the application of light having selected wavelengths in order to promote the development of embryos of a selected sex. An incubating device is provided having an interior cavity that can be sealed from an outside, and having a plurality of lighting elements disposed on each of a plurality of trays disposed in the interior cavity. Eggs are disposed on the trays, and pre-determined environmental conditions are applied to the interior cavity to promote hatching of the eggs. Concurrently with the application of the environmental conditions, the eggs are irradiated according to pre-determined lighting conditions. The lighting conditions include applying light having wavelengths substantially concentrated in selected ranges, such as light wavelengths within the 390-419 nm, 410-450 nm, 420-450 nm, 450-495 nm, or other narrow range.
