This experiment was conducted in the poultry field of the College of Agriculture / Kirkuk University, To study the effect of using two different concentrations of Bedgen 40 at different periods in the drinking water of broilers and their effects on some physiological traits. For the period from 9/30/2021 to 11/11/2021, 280 chicks of the of Ross 308 unsexed were used at one day old, and the average weight was (42 g per chick). The chicks were randomly distributed to seven treatments, with 4 repetitions, and each replicate was 10 birds. Bedgen 40 was added to the drinking water at three different periods, and the experiment parameters were as follows: T1 as the control treatment without any addition, while Bedgen 40 was added in the T2 and T3 treated drinking water at levels of 35 and 45 cc / liter at the age of 6-10 days, The addition of Bedgen 40 in the treated drinking water T4 and T5 at levels of 35 and 45 cc/ liter at the age of 21-25 days, the addition of Bedgen 40 in the treated drinking water T6 and T7 at levels of 35 and 45 cc/ liter at the age of 31-35 days. The addition of Bedgen 40 led to an improvement in the status of antioxidants, as an increase in the level of GSH and a decrease in the MDA metrics for birds treated with Bedgen 40 compared to the control treatment. The addition of Bedgen 40 led to a significant (P<0.05) decrease in Triglycerides (TG) and LDL, and a significant (P<0.05) increase in HDL concentration for T2,T3,T4,T5 treatments
