Dietary supplementation of protexin and artichoke extract for modulating growth performance and oxidative stress in broilers

Application of phytobiotic and probiotic in poultry production can positive effect on performance and produce healthy protein source for human. In this study, the effects of one commercial probiotic and phytobiotic was evaluated on chicken performance. Totally, 300 chicks were divided into 4 groups that fed basal diet, diet containing probiotic (Protexin), phytobiotic (AE), and probiotic (Protexin) plus phytobiotic (AE) in all over the growing period. The growth indices were measured weekly and analyzed in 21 and 42 days of age. At the 42 days of age, blood samples were collected from all chickens. The concentration of liver enzymes, lipid profiles and antioxidant status were measured in blood samples. Results showed that the weight gain was significantly higher and FCR significantly lower in chickens received probiotic, or probiotic plus phytobiotic in comparison with chickens received phytobiotic and control chickens (p
