| Abstract | ||
| One hundred and twenty, one day old unsexed Lohman broiler chicks were used to study the effect of supplementing aqueous extract and powder of chamomile flowers to diet and drinking water on some physiological characters of broiler exposed to high environmental temperature 28 – 30 – 28 ◦ C to alleviate heat stress. Five treatments were carried out, treatment T0 without supplementing chamomile to drinking water or diet, treatments T1 and T2 supplementing with 0.3 and 0.6% of aqueous extract to drinking water, treatments with T3 and T4 supplementing 0.6 and 0.9% of chamomile flowers powder to diet. This supplementation of chamomile to drinking water and diet had been given to birds daily for 6 hours from 1200-1800 and during the highest environmental temperature and during the experiment period from 4 – 8 weeks of age. The result revealed that body temperature reduced significantly of treatments T3 and T4 compared with other treatments however heterophil lymphocyte ratio reduced significantly while hemoglobin increased in all treatments compared with T0, also glucose reduced significantly of treatments T1, T2 and T3 compared with T0, packed cell volume, RBC count, total protein, cholesterol, uric acid, dressing percentage and percentage of some internal organs revealed significant results of some treatments and non significant results of some other treatments. The study confirmed that supplementing the aqueous extract and powder of chamomile flowers lead to alleviate heat stress by positive effects on some physiological characters. The results pointed that chamomile flowers powder supplementation gave better results than aqueous extract | ||
