Meat spots

Description

Most meat spots are pieces of tissue from body organs, but some may be partially broken-down blood spots. They are usually brown in colour, and found in the thick albumen, chalazae, or the yolk. They range in size from 0.5 mm to more than 3 mm in diameter.

Incidence

The incidence of meat spots ranges from less than 3% to 30% or more. It varies with the strain of bird, increases with the age of bird and may be higher in brown eggs. Many meat spots are too small to be detected by candling, especially in brown eggs. Less than 1% of eggs are usually downgraded because of meat spots.

Cause Control
Ageing of bird Keep flock age as low as economically possible.
