The study evaluates the blue-green alga, Spirulina, as the sole dietary source of protein in sexually maturing rats. A diet containing Spirulina protein was compared to diets containing no protein, protein in sodium caseinate, and protein in cereal-base, commercially-produced food specifically designed for the laboratory rat. Spirulina as the sole protein source proved adequate to support normal growth and sexual maturation. The conclusion is based on body weights, organ weights, testicular histology, hematological data, and levels of gonadotrophic hormones, luteinizing hormone, follicle stimulating hormones, and prolactin. The protein efficiency ratios show Spirulina to be of comparatively good protein quality. Thus, Spirulina shows promise as a protein-rich food source
