Abstract EN
The research was conductedat the poultry research Unit, karabo Farm, Agriculture Faculty, Damascus University between14 August, 2011 and 6 October, 2012.
A total of 504-one day old chicks from hybrid chicken hens (Babcock B-300), producing white eggs, were randomly distributed into two groups with three replicates in each group, Chicks were raisedin similar conditions (short constant lighting until 17weeks of age), whereas during production period (until 60 weeks of age), a constant lighting programme was applied for first group and an intermittent lighting programme was used for second group.
During the production cycle a total of 45 eggs from each group were randomly collected (5 eggs per replicate) at three ages, 22, 38, and 58 weeks of age in order todetermine the percentage of unsettable eggs, egg weight, egg density, shell thickness, albumen index, yolk index, white to yolk ratio, haugh units and yolk color degree.
Results showed that using intermittent lighting during production period had improved the average egg weight as well ashaugh units.
All studied parameters were affected by age, as they were significantly higher at the onset of egg lay compared to the end of egg lay.
