The Effect of different levels of algae (Spirulina) on growth performance, intestinal morphology, gut microflora, carcass characteristics and some blood parameters in broiler chickens

Introduction: The Effect of different levels of algae (Spirulina platensis) on growth performance, intestinal morphology, gut microflora and some blood parameters in broiler chickens was investigated in this study. Materials and methods: Experimental diets included control diet (with no additive), ۳ levels of algae (۱, ۱.۵, ۲ g/kg diet), and one level of prebiotic (۱ g/kg diet) as a positive control were fed to birds from ۱ to ۴۲ d of age. Results: The results showed that adding Spirulina algae to diet increased body weight gain and decreased feed conversion ratio during starter (۱-۱۰ d), grower (۱۱-۲۸ d) and whole period of rearing (۱- ۴۲ d) in comparison with other groups (P
