Effect of replacement dietary hot red pepper (capsicum) on performance, carcass characteristics, some blood parameters and lymphoid organs of broilers chickens

Because of the effective substance capsaicin in the chili peppers have medicinal properties and are used as growth promoters in animal
This study was conducted to investigate on the effects of different levels of hot red pepper powder (HRPP) (0, 0.5, 1 and 1.5 percent) with 15 mg/ kg avilamycin on performance and some blood parameters of broiler chickens.
Three hundred one-day-old male broiler chicks (Ross- 308) in 5 treatments and 5 replicates and 12 birds in each repetition were allocated. The experimental treatments were analyzed in completely randomized design.
Body weight gain of chicks fed 1% HRPP was greater than control and 1.5% fed ones (P 0.05). Weights of spleen and bursa of birds fed 1.5% HRPP was higher than other birds (P It was concluded that feeding 1% HRPP caused the highest growth and efficiency in broiler chickens. Also, consumption of the fed 1.5%HRPP weight gain Bursa of Fabricius and spleen and decreased blood cholesterol.
