The effect of use red pepper (Capsicum annum L) and black pepper (Pipernigrum L) on performance and hematological parameters of broiler chicks

Abstract

The objective of this study was to determine the effect of use of red pepper, black pepper and their mixture powder on performance of broiler chicks. 320 one day old Ross 308 chicks were used in this study. Chicks were fed by basal diet as control, 0.02% red pepper (T1), 0.02% black pepper (T2) and 0.01% red pepper + 0.01 %black pepper powders (T3). Feed intake, body weight gain, feed conversion ratio were determined. At the end of trial 4 chicks form each group were separated and slaughtered. Cholesterol, triglyceride, glucose levels and antibody titer against new castle vaccine were investigated. The result revealed that the inclusion of red and black pepper in broilers diet improved body weight gain, feed intake and conversion ratio. in addition use of red and black pepper depressed the cholesterol, triglyceride and glucose concentration and decreased H/L ratio concentration in broiler's blood plasma (p
