Abstract
One hundred and twenty, one day old unsexed Lohmann broiler were used to study the effect of supplementing aqueous extract and powder of oat seeds to diet and drinking water on some productive characters of broiler exposed to high environmental temperature 28-35-28◦ C to alleviate heat stress. Five treatments were carried out treatment T0 without supplementing oats to drinking water and diet, treatments T1, T2 supplementing 0.1,0.25% of aqueous extract to drinking water, treatments T3, T4 supplementing 0.25,0.50% of oat to diet. This supplementation of oat to drinking water and diet given to birds daily for 6 hours from (1200-1800) and during the highest environmental temperature and during the experiment period 4-8 weeks. The result revealed that body weight increased significantly in T2,T3,T4 compared with T0,T1 at 6, 8 weeks of age, and weight gain reduced significantly in T1,T2 compared with other treatments meanwhile feed consumption increased significantly at 8 week of age in T2,T3 compared with other treatments, feed consumption pattern reduced mostly significant as temperature periods increased at 1200-1800 h for all treatments compared with T0 while water consumption pattern revealed opposite results, also body temperature reduced significantly at 1200-1800 h for all treatments compared with T0. The result pointed that there were improvement in productive character by giving oat seeds aqueous extract and powder to broiler exposed to heat stress.
