Abstract: Provided herein are methods for promoting production of male embryos in avian eggs, utilizing a composition which includes Ginseng extract, Vitamin D and/or folic acid. Further provided are systems for delivering one or more substances for promoting the production of male embryos in avian eggs via a humidity unit of an incubator in which the fertilized avian eggs are incubated.

Abstract: 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.

Abstract: There is provided herein a system and a method for promoting production of female embryos in eggs. The method comprises the steps of: incubating a plurality of fertilized eggs to promote hatching of the fertilized eggs; and transmitting a soundwave having a frequency ranging from 100 Hz to 1200 Hz to the fertilized eggs, thereby promoting production of female embryos in the fertilized eggs.
