Dominant lethal assay of Spirulina maxima in male CD-1 mice after short-term and prolonged-term feeding

Spirulina algae, incorporated into experimental diets at levels of 10, 20 or 30%, was given to groups of adult CD-1 mice. Short-term (5 d) and prolonged-term (5 d/week, for 10 weeks) feeding, was followed by mating with untreated adult virgin females. Examination of uteri and ovaries of pregnant females on d 12-14 of gestation for counting preimplantation losses and non-living implants failed to reveal dominant lethal effects.
