This study was done to investigate the effect of microencapsulated and non-encapsulated Spirulina (Spirulina platensis) powder on the antioxidant enzymes activityand nutrient digestibility of broiler chicks for 6 weeks. A total of 360 one-day old broiler chicks (male) Ross 308 strain was divided into 9 treatments, 4 replicates (10 chicks in each replicate) in a completely randomized design. Experimental treatments include: basal diet without any additives (negative control), basal diet + antibiotic (positive control), 1-basal diet + vitamin E, 2-basal diet + 0.33% Spirulina microencapsulated, 3-basal diet + 0.66% Spirulina microencapsulated, 4-basal diet + 1% Spirulina microencapsulated, 5-basal diet + 0.33% non-encapsulated Spirulina, 6-basal diet + 0.66% non-encapsulated Spirulina and 7-basal diet + 1% non-encapsulated Spirulina. Results showed that the blood super oxide dismutase activity increased in chicks fed with encapsulated Spirulina powder and non-encapsulated Spirulina powder at the level of 1 percent (p < 0.05). But the activity of catalase and glutathione peroxidase enzymes did not show any significant difference (P>0.05). The effect of experimental treatments on nutrient digestibility showed that no significant different experimental groups (P>0.05). The addition of spirulina powder and encapsulated spirulina powder increased antioxidant activity in the diet of Ross 308 broiler chicks.
