Effects of Scenedesmus microalgae and virginiamycin antibiotic on blood parameters of broiler chicks

Introduction: It is well shown that microalgae have positive effects on blood parameters. They can reduce the serum concentration of lipids and glucose. This study was done to investigate the effects of Scenedesmus microalgae on some blood parameters of broilers. Materials and methods: Birds were randomly assigned to each of 5 dietary treatments. Treatments consisted of: T1 (basal diet (BD)+ tap water), T2 (BD+ (50% tap water+ 50% SM), T3 (BD + (25% tap water +75% SM), T4 (BD + (0% tap water + 100% SM) and T5 (BD + 25mg Virginamycin/kg diet) with 4 replicate cages of 10 birds each. Birds were bled to determine some blood biochemical parameters at the end of the experiment (day 42). Results: The birds receiving T4 diet had higher white blood cell concentrations, and lower serum content of triglycerides and cholesterol compared with the control group (P<0.05). Conclusion: It was concluded that Scenedesmus microalgae, at high levels, can affect white blood cells, triglycerides and cholesterol
