The study was carried out to evaluate the growth performance of colour synthetic broiler chicken fed with sun dried Azolla as protein substitute. The 150 day-old broiler chicks of either sex were distributed randomly in five dietary treatments with 3 replicates each, C1: basal diet, T1: basal diet + 10% dietary protein from Azolla, T2: basal diet + 10% dietary protein from Azolla + enzyme, T3: basal diet+ 15% dietary protein from Azolla, T4: basal diet + 15% dietary protein from Azolla + enzyme. The experiment was carried out for 92 days for evaluating performance with respect to body weight, body weight gain, feed consumption, feed conversion ratio (FCR), and economics of production. Each of the Azolla fed group, compared to control, showed significantly (P≤0.05) higher body weight. T4 showed higher gains than T1 till 4th week whereas no significant (P≥0.05) difference was recorded between the Azolla fed groups from 5th week onwards. Azolla fed group registered significantly (P≤0.05) higher consumptions than the control from 2nd week. However between the two non-enzymes groups T1 showed higher (P≤0.05) values than T3. Enzyme supplementation resulted in a lower consumption in 10% Azolla group while it led to a higher consumption in 15% Azolla group, and that between the two enzyme groups, group T4 showed higher values (P≤0.05) than group T2. Throughout the experiment feed efficiency of Azolla fed group showed higher than the control. Cost benefit analysis on basis of net return/bird or net return/kg live weight, each of Azolla fed groups showed higher economic efficiency than the control. It was concluded that Azolla could be included in the broiler ration up to 15% level which resulted in higher body weight gain and feed efficiency. It leads to substantial economisation of feed cost of production.
