Effect of Spirulina supplementation on growth performance of broilers

The experimental trial of six weeks was undertaken on 90 broiler chicks divided into three groups. Control (T₀) group was fed standard broiler diet and T₁ and T₂ groups were provided same broiler diet supplemented with 300 and 500 mg of Spirulina per kg feed, respectively. Mean live body weight of six weeks of the experiment and live weight at the end of experiment were found to be significantly (P<0.05) higher in Spirulina supplemented T₁ and T₂ groups of broilers than that of control (T₀) group. Comparatively better mean weekly weight gain and feed efficiency were also observed in Spirulina supplemented groups (T₁ and T₂) with decreased feed consumption as compared to control (T₀) group of broilers.
