This research was conducted to study the effect of adding different levels of Lycopene powder to the ration on
some productive and egg quality parameters of laying hens ISA-Brown. Used in this experiment 345 layer hens
ISA Brown and were 23 week old were randomly allotted in 5 groups , 3 replicates ( 23 hens per replicate) For
the period from 7/1/2013 to 23/6/2013 . Experiment included five treatments and by the following: First
treatment : a negative control group without of any addition , treatment second group control positive was added
200 mg / kg feed (vitamin E) to the ration , and treatments, third, fourth and fifth represents add lycopene
powder into the ration at rates 100 150 and 200 mg / kg feed respectively . Included experiment estimate some
productive and egg quality parameters: ( egg production , the cumulative number of eggs , egg weight , egg
mass, haugh unit , the relative weight of the shell and shell thickness ) .The results of the experiment to get
significant improvement (P <0.05) for treatments lycopene powder and vitamin E treatment in the egg
production parameter , the cumulative number of eggs , egg weight , egg mass, haugh unit , the relative weight of
the shell and shell thickness.production during the periods as compared to the first treatment ( control). However,
recorded fifth-treatment (in addition to 200 mg lycopene / kg feed) the best results .
