To produce chicks from hatching eggs, the eggs are incubated in a hatcher incubator. After hatching, chicks of lesser quality are screened out, and the remaining chicks are transferred to a poultry barn. During the first week in the barn, a number of chicks are lost. When the loss rate exceeds a certain value, treatment with antibiotics is usually applied. Methods and compositions for reducing the loss rate during the first week and thus the number of antibiotic treatments are disclosed. The methods include providing in the air of the hatcher incubator at least during a final stage of the incubation and hatching of the eggs in the hatcher incubator, an active amount of a pheromone composition with the appeasing effect of the mother hen pheromone. The pheromone composition can be applied in the hatcher incubator at a specific height in the form of a formulation.

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.

Disclosed are methods of reducing incidence of disorders such as Woody Breast in poultry, by incubating pre-hatching eggs in an atmosphere enriched in carbon dioxide, preferably combined with administration to the post-hatching birds of water comprising oxygen-containing nanobubbles.

A system and method to promote biological responses within incubated eggs using lighting devices within an incubation chamber. A light supporting device is installed within the incubation chamber in spaced relation to an incubation device housing a plurality of eggs. The light supporting device is positioned to direct light at pre-determined wavelengths into the interior cavity of the incubation device to irradiate the plurality of eggs to promote a biological response within the eggs.

An improved poultry production method comprising providing dry hydrogen peroxide (DHP) to poultry eggs, chicks and birds, and devices for providing DHP to poultry production during laying, incubating, hatching, and growing.

The invention relates to the use of a cyclone separator for separating keratin particles originating from poultry out of a gas, in particular air. The separated particles comprise down particles. The invention furthermore relates to a climate chamber for hatching eggs and/or keeping poultry. Said climate chamber comprises a substantially closed compartment having two opposite side walls provided with one or more passages; as well as a substantially closed duct which extends outside the compartment and connects one of said side walls to the other of said side walls so as to form a substantially closed circuit together with the compartment. Said climate chamber furthermore comprises a cyclone separator, the inlet of which ends in the substantially closed duct and the outlet of which ends outside the closed duct for discharging into the environment.
