The Effects of Different Levels of Lemon Pulp Consumption and Reduction of Energy and Protein of Diet on Growth Related Hormones, Blood Parameters and Performance of Broiler Chickens

The aim of this study was evaluation the effects of energy and protein decreasing of diet with using of different levels of lemon pulp intake on growth related hormones, blood parameters and performance of broiler chickens. Lemon pulps used as a dietary replace for nutrient. A total 240 one-day old broilers (Ross 308) were randomly divided to 4 treatments (4 replicate with 15 birds per pen). Four experimental treatments supplemented with 0, 4, 8 and 12 percent of lemon pulp. At the end of experimental period, performance values were calculated and sera separated from blood samples were used for measurement of hormones level by ELISA technique and biochemical parameters by auto analyzer system. The results showed that the rations containing of lemon pulp had significantly decreased body weight in broilers at the end of starter and finisher periods (P
