Candling

Candling is a poultry technique used to inspect eggs by shining a light through them to assess embryo development and identify infertile or deceased embryos. The process typically involves using a bright LED lamp and is performed at specific stages during incubation, such as days 7-10. This method helps optimize incubator space and reduces contamination risks by allowing for the removal of non-viable eggs.

CANDLING

Candling in poultry refers to the process of shining a light through an egg to


inspect its contents, particularly during incubation. This allows for the
assessment of embryo development, detection of infertile eggs, and
identification of eggs with deceased embryos.

Here's a more detailed explanation:


 Purpose:
Candling helps monitor embryo development, identify infertile eggs, and detect early
mortality of embryos during incubation.
 Method:
A light source, often a bright LED lamp, is used to illuminate the egg from behind or
beneath. This makes the eggshell translucent, allowing observation of the contents.
 Observation:
By candling, one can observe the air cell, yolk, blood vessels, and the developing
embryo (if present).
 Timing:
Candling is typically performed at specific stages during incubation, such as around
days 7-10, to assess embryo development and identify any issues.
 Benefits:
Candling allows for the removal of infertile or deceased eggs, optimizing incubator
space and reducing the risk of contamination from rotting eggs.
