Abstract
One hundred and twenty unsexed day old chicks (Lohman) were used. The Study aimed to investigate The effect of supplementation aqueous extract and powder of red pepper fruit, to water,diet for (6) hours during heat stress (1200-1800 h) on the productive and physiological characters of broiler chicks reared under high cyclic temperature (28-35-28) º C. Five treatments were carried out, the control treatment (T0), no red pepper supplementation to drinking water and diet. The treatments (T1, T2), supplementation of 0.3, 0.6% a aqueous extract of red pepper fruit to drinking water and the treatments (T3,T4) supplementation of 0.6, 0.9% of red pepper fruit powder to feed. Results of supplementing red pepper fruit caused a significant (P < 0.01) increased in body weight, weight gain, feed consumption for T1, T2, T3, T4 as compared with T0 at 5 weeks of age while at 6 weeks of age there were a significant increased in body weight T3, T4 compared with T0, and also weight gain increased significantly in T1, T2, T4 compared with T0 while feed consumption increased significantly for all treatments compared with T0.No significant effect of dressing percentage and the percentage of liver, heart, gizzard, spleen, bursa of fibricious. Also the results revealed that there were a mathematical increased for all treatments compared with T0 for packed cell volume, red blood count, hemoglobin Hb, lymphocytes L% while a significant reduction in heterophil / lymphocyte ratio in T2 compared with T0. Plasma protein increased mathematically while uric acid decreased also glucose reduced significantly in T1compared with T0, meanwhile a significant reduction in cholesterol in T1, T2, T3 compared with T0. Body temperature at 5 weeks of age revealed that there were a significant reduction in body temperature in treatments T1, T3 at 1200 h, treatment T1 at 1500 and treatments T2, T4 at 1800 h, and at 7 weeks of age the reduction were in treatment T1 at 900, 1200 h, treatments T1, T3 at 1500, treatment T3 at 1800 h, treatment T4 at 2400, treatments T2, T4 at 900h compared with T0, and an increase in treatment T3 at 600h. The study refer that there were an important of supplementing red pepper fruit to alleviate heat stress of broiler exposed to heat stress.
