Abstract
The present study was designed to evaluate the productive performance of commercial broiler chicks fed Spirulina platensis and chlorella vulgaris algae containing diets. Four hundred and twenty day-old unsexed Cobb broilers chicks were used in this experiment. Birds were legs-banded, individually weighed, and randomly distributed into seven equal experimental groups; with three replicates of 20 chicks each. The average initial body weights of the treatments groups were nearly similar without significant differences. Chicks were kept in floor pens and subjected to 23 h. lighting along the experimental period which extended to 6 weeks of age. The house temperature was maintained at about 34ºC during the first 3 days, 32ºC during next 4 days and thereafter, gradually decreased by 3ºC weekly down to 24ºC. Basal control diet was formulated to contain 3100 kcal ME/kg and 23.01% crude protein during the starting period (till 21 days of age) followed by 3200 kcal ME/kg and 20.05% crude protein during the finishing period (21-42 days of age). The basal control diet was supplemented with spirulina and/or chlorella powder at levels of (1 g spirulina), (2 g spirulina), (1 g chlorella), (2 g chlorella), (0.5 g spirulina + 0.5 g chlorella), and (1 g spirulina+1 g chlorella/kg of diet, respectively). The obtained results cleared that birds fed 2 g spirulina/kg diet achieved superior means of body weight, body weight gain, and feed conversion ratio compared to the control group and the other treatments.
