Growth, carcass criteria and blood biochemical parameters of growing quails fed Arthrospira platensis as a feed additive

This study investigated the impact of Arthrospira platensis (A. platensis) as a dietary supplement on growth, carcass criteria, liver and kidney function, lipid profile, and immunity of growing Japanese quails. In a 28-day experiment, 240 un-sexed 7-day-old quail chicks were used. The quail chicks were divided into four treatment sets, each comprising six replicates and ten quail chicks. Group (1) fed the basal diet with no supplements, group (2) fed the basal diet supplemented with 0.25 g A. platensis /kg diet, group (3) fed the basal diet supplemented with 0.50 g A. platensis /kg diet, and group (4) fed the basal diet supplemented with 1.00 g A. platensis /kg diet. The results of this study revealed that the birds that were fed 0.50 g. or 1.00 g A. platensis kg−1 diet had superior final body weights, body weight gains, feed conversion ratios, and carcass criteria compared to control, furthermore, had significant (p
