Devices and methods for promoting production of female embryos in eggs

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.

         23 . A method for promoting production of female embryos in eggs, the method comprising the steps of:
 incubating a plurality of fertilized eggs to promote hatching of the fertilized eggs; and   transmitting a soundwave having a defined frequency to the fertilized eggs, thereby promoting production of female embryos in the fertilized eggs.   
     
     
         24 . The method of  claim 23 , wherein said fertilized eggs are chicken eggs. 
     
     
         25 . The method of  claim 23 , wherein said incubating is performed for a duration of about 21 days. 
     
     
         26 . The method of  claim 23 , wherein the soundwave is transmitted or intermittently transmitted during incubation. 
     
     
         27 . The method of  claim 23 , wherein the soundwave is transmitted or intermittently transmitted during the first 14 days of incubation. 
     
     
         28 . The method of  claim 23 , wherein the soundwave is transmitted or intermittently transmitted during one or more predetermined time periods within the incubation period. 
     
     
         29 . The method of  claim 28 , wherein the defined frequency of the soundwave varies between the one or more predetermined time periods. 
     
     
         30 . The method of  claim 23 , wherein transmitting the soundwave varies depending on an incubation day. 
     
     
         31 . The method of  claim 23 , wherein transmitting the soundwave comprises intermittently transmitting soundwaves on defined incubation days. 
     
     
         32 . The method of  claim 23 , wherein the defined frequency ranges from about 100 Hz to 1200 Hz. 
     
     
         33 . The method of  claim 32 , wherein a frequency during a first predetermined time period ranges from 600 Hz to 700 Hz. 
     
     
         34 . The method of  claim 33 , wherein a frequency during a second predetermined time period ranges from 500 Hz to 600 Hz. 
     
     
         35 . The method of  claim 34 , wherein a frequency during a third predetermined time period ranges from 500 Hz to 700 Hz. 
     
     
         36 . The method of  claim 23 , wherein a duration of a predetermined time period ranges between 10 minutes to 5 hours. 
     
     
         37 . The method of  claim 23 , wherein a pause between two successive predetermined time periods ranges between 1 hour to 5 days. 
     
     
         38 . The method of  claim 23 , wherein said incubation is performed under at least one controlled environmental condition selected from humidity and temperature. 
     
     
         39 . The method of  claim 38 , wherein the humidity ranges from 50% to 80%. 
     
     
         40 . The method of  claim 38 , wherein the temperature ranges from 36° to 38° Celsius. 
     
     
         41 . The method of  claim 23 , wherein the resulted percentage of female hatchlings is over 75%. 
     
     
         42 . A system comprising:
 an incubator for incubating fertilized eggs under predetermined environmental conditions to promote hatching of the fertilized eggs;   a soundwave transmitter configured to transmit a variable frequency ranging from about 100 Hz to 2000 Hz during incubation to promote production of female embryos in the fertilized egg; and   a controller configured to operate the transmitter.
