Effects of Spirulina (S. platensis) Addition to Diets of Breeder Quails

Abstract

Abstract The experiment aimed to investigate how different levels of Spirulina (spirulina platensis) supplementation in the diet of breeder Japanese quail (Coturnix coturnix japonica) affect their laying performance, egg quality, and hatchability parameters. The study was carried out with 96 breeding quails (72 female, 24 male). Quails were randomly distributed to 4 treatment groups with 24 subgroups (1 male 3 female). The feeding trial lasted for 8 weeks, during which time four diets were prepared with powdered Spirulina supplementation at 0% (control), 0.75%, 1.5%, and 2.25% to the basal diet. At the end of the experiment, feed consumption was higher in the control group than in the other groups (P
