Effect of Microencapsulated of Spirulina (Spirulina Platensis) Algae Powder on Performance, Carcass Characteristics and Intestinal Microflora of Broiler Chickens

This research was conducted to evaluate the effect of microencapsulated Spirulina (Spirulina platensis) powder on performance, carcass characteristics and intestinal microflora of broiler chicken. A total of 360 one-day old broiler chicks (male sex) Ross 308 strain was divided in 9 treatments, 4 replicates and 10 chicks in each replicate in a completely randomized design. Experimental treatments include: basal diet, basal diet antibiotic, basal diet vitamin E, basal diet 0.33 % Spirulina, basal diet 0.66 % Spirulina, basal diet 1 % Spirulina, basal diet 0.33 % microencapsulated Spirulina, basal diet 0.66 % microencapsulated Spirulina, basal diet 1 % microencapsulated Spirulina. Results showed that during grower period the feed intake of group fed with 0.33 percent Spirulina was higher than control group (P
