The experiment was carried out with 6 boars from Danube White breed in the experimental animal base of the Agricultural Institute in Shumen, Bulgaria. In the experimental period to the main diet was added 7 ml/per head the fresh biomass of microalgae preserved by melasa (final quantity - 1,4 mg Spirulina platensis). The obtained results shown that the addition of Spirulina improves the sperm parameters in boars: the volume of the ejaculates increased with 30 ml in experimental period (306 ml against 276 in control, P is less than 0.05) as well as the spermatozoa concentration enhanced with 27 mln/ml. The total dehydrogenase activities estimated by reaction with methylene blue as well as LDH activity were higher in the experimental period. Also the survivability of the spermatozoids at 24, 48 and 72 hour in the experimental periods was more than in the control.
