This study was conducted to assess the effect of different ratio of Rapeseed meal on some productive and physiological characteristics in Broiler chickens This study include 63 bird sample with age of 21 days that had been divided into 3 groups treatment with (control (C) 0% , T1 5%, T2 10% ) of Rapeseed meal respectively and each group included to three replication .

The poultry dietary and water were supplied freely in front of birds during whole study period .

The results were as follow : 1- There was no significant differences in bird weight in all treatments.

And there was significant decrease in feed intake and significant increase in feed conversion ratio (FCR) in T2 in comparison with (C , T1) 2- There was no significant differences in uric acid serum concentration for all groups and significant increase in serum cholesterol in T2 in comparison with (C , T1).

There were significant differences between all groups in serum glucose level.

There was significant decrease in serum glucose level by increase the Rapeseed meal ratio (5%, 10%) respectively in comparison with control .

According to results , it could be used Rapeseed meal with 10 % ratio in Broiler chickens feed that gives the best FCR.
