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 in the interior cavity. Eggs are disposed in the interior cavity, 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 440-460 nm, or other narrow range.

A system for handling eggs includes a pusher comprising an axis and an egg support at a free end of the axis. The system for handling eggs further includes a brake associated with the pusher, to selectively apply a brake force thereon.

The present invention relates to a method for promoting production of female embryos in fertilized eggs, comprising steps of :incubating said eggs; generating at least one type of energy with a predetermined energy profile; and simultaneously generating a pre-determined profile of a non-energy parameter by means of an energy generation device, applying both energy profile and the non-energy parameter to the eggs; and, collecting the eggs; wherein said method is non-toxic to the embryos, the application of both the energy profile and the non-energy parameter increases the fraction of females in the hatched chicks.

Provided are methods and compositions an organism of the order Clostridiales for improving the health of an avian, wherein an effective dose of the composition is applied to an outer surface of an egg containing the avian as an embryo prior to hatching. Also disclosed are compositions comprising a strain within the order Clostridiales selected from the group consisting of Caldicoprobacteraceae; Christensenellaceae; Clostridiaceae; Defluviitaleaceae; Eubacteriaceae; Graciibacteraceae; Heliobacteriaceae; Lachnospiraceae; Oscillospiraceae; Peptococcaceae; Peptostreptococcaceae; Ruminococcaceae; Syntrophomonadaceae and combinations thereof and their use in such methods.

A method and a device for treating poultry eggs with an electron beam bundle to sterilize the calcareous shell are disclosed. The method includes moving at least one egg through the beam path of an electron beam source; irradiating the eggs, whereby the calcareous shell is irradiated with a varying dose; and either carrying out an irradiation encompassing all regions of the calcareous shell of the egg by employing the electron beam bundle, whereby an element is inserted into the path of the electron beam bundle; carrying out an irradiation of a rolling/rolled egg by employing the electron beam source in the path of the electron beam bundle; or carrying out an irradiation of the held eggs by employing the electron beam source in the electron beam bundle path at a zero degree position of one side in a device arranged upstream of a turning device.

An egg grasp device is provided. Such a device includes a body and a plurality of elongated members extending from the body. The elongated members are interlaced to form a sheath capable of retaining an egg. The sheath has a distal end and a proximal end at which the elongated members are operably engaged with the body. The elongated members cooperate to define an opening at the distal end through which an egg is received when the elongated members engage and deflect about an egg such that the egg is seated within the sheath. Associated systems and methods are also provided.

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.
