The objective of the present study was to evaluate the effect of spirulina (Arthrospira platensis) inclusion in diets over productive parameters of intestinal morphometry and tibial morphometry on 21 days old broiler chickens. For this purpose, 40 Rose 308 1-day old male chicks were used, which were randomly distributed in eight experimental units of five birds each. Four experimental units were fed one of the following treatments: T1: Control diet and T2: Diet with 0.15% spirulina for 21 days. The feed (as meal) and fresh water were given ad libitum. Live weight, weight gain, feed consumption and feed conversion ratio were registered weekly. At day 21, all animals were sacrificed and breast weight, depth, width and length were registered. Internal organs (intestines, heart, gizzard, liver, pancreas and cecum) were extracted for respective measures. For tibial morphometry (weight, length, width) tibias were stored. In the same manner, intestine samples were saved for intestinal morphometry (intestinal villi length, width and area, crypt depth and length-area ratio). Registered data was submitted to analysis of variance under a Completely Randomized Design (CRD) and for mean comparison Tukey Test was employed. The results showed that productive parameters were not influenced (P>0.05) by spirulina inclusion at 0.15%. Heart, liver and feet weight were influenced (P>0.05) by spirulina inclusion in diet. Intestinal morphometry and tibial integrity indicators were not affected by dietary treatment (P>0.05). In conclusion spirulina inclusion at 0.15% did not affect productive parameters of intestinal villi length nor tibial morphometry of birds.
