UTSTANDING DURING EGG AND REVERSAL hatching



    
The position and the reversal during the hatching eggs are very important

    
considered in order to obtain a high hatchability. The position of eggs during

    
in hatching, the dull side should be placed above.

    
Reversal of eggs is usually done by turning left or 450

    
right with a total playing 900 and the result is quite satisfactory.

     
The number of playback eggs in commercial hatcheries, enough

     
3 to 4 times per day from the start hatching eggs inserted into the machine

     
until day 18. Screening aims for the surface of the yolk (yellow

     
eggs) are not attached to the membrane of the egg shell that will reduce

     
hatchability. If playback is too often, then this is less

     
practical, although may increase hatchability. Hatchability above

     
85% is considered quite good. Hatchability is calculated by

     
calculate the percentage of eggs that hatch from eggs which is num

     
inserted into the machine or the number of hatching eggs fertilized

     
(Fertile).

     
When the engine tetas tetas machines traditionally used, then

     
screening of eggs is usually only reversed by hand and

     
playback is in itself less than perfect. Therefore power

     
tetasnya also not good. Conversely when used machines that tetas

     
modern egg playback can be done automatically stay

     
tool set, in accordance with the desired.
