Tamarind seed coat is composed of polyphenols especially procyanidin oligomers. The objective of this experiment was to determine the effect of polyphenols extracted from tamarind seed coat on differential white blood cell counts of broilers maintained at high environmental temperature. Broilers were divided into 2 groups. In group 1 broilers were maintained in environmental temperature at 26 2oC throughout experimental period and in group 2 broilers were maintained in environmental temperature at 38 2oC and received polyphenols . 0 100 200 300 400 and 500 mg kg in diets. Differential white blood cell counts were investigated on days 1 7 14 and 21 of experimental period. The results revealed the following information Lymphocyte and basophil levels of broilers maintained in the environmental temperature at 38 2oC and received polyphenols at 400 mg kg in diet were increased p . On the other hand the heterophil and monocyte levels of broilers maintained in the environmental temperature at 38 2oC and received polyphenols at 400 mg kg in diet were decreased p . This occurrence indicated that polyphenols extracted .
