PECIAL HANDLING FOR MAINTAINING EGG hatchability


At one time the eggs are produced need to be stored for several days
since in tetas machine is full. Under these conditions, eggs
do not store more than one or two weeks because it requires
special handling to maintain its tetasnya, including:
a. Storage Temperature.

    
Egg storage temperature should not be too hot or too

    
cold. When the temperature of the hot environment (> 270 C) embryos will

    
growing, but growth was not normal and most die

    
before or after being in hatching machines. Conversely if

    
stored at a temperature that is too cold it will hatchability

    
decreased. A good egg storage temperature is about 18.30 C

    
when eggs stored no more than 14 days. When the eggs are stored

    
more than 14 days, then the storage of eggs of about 10.50 C. Before eggs

    
stored, must be fumigated prior typically use

    
KMnO 4 and formalin 40%.
b. Humidity Storage.

    
During the storage, eggs from the preformance will happen

    
evaporation which causes the air cavity in the egg becomes large.

    
To prevent this evaporation can be done with

    
increasing storage humidity. Humidity storage

    
A good egg is about 75-85%.
c. Old storage.

    
When eggs are stored for too long, then hatching will continue to decline.

    
Therefore, on the condition of the company usually eggs hatched in

    
2 times per week. Thus the eggs are put into

    
tetas machine is the age of 3 days, 2 days, and one day. According to

    
some research results, a good egg storage duration is about

    
1-4 days.
d. Position Eggs During Storage.

    
Eggs should be placed on the egg tray with the blunt

    
placed on top. This is to keep the air space in

    
eggs remain a blunt tip. As it is known that the air space

    
This is needed by the embryo for its development. When the location

    
air in the room shifted from the tip blunt, egg hatchability will decrease.
e. Screening eggs during storage.

    
When the eggs are stored more than one week, the eggs should be played with

    
total playback 900. For eggs stored less than one

    
weeks, the playback is not required.
