The research was conducted to explore the effect of incoherent polarized light emitted by the lamp “Bioptron Compact III” on the general state of bulls-sires, morphological, biochemical parameters of their blood and quality of sperm. The experiment was made on 12 imported bull-sires of the Holstein breed aged 4–11 years old, which were formed into two groups — experimental and control (6 heads in each group) by the principle of analogues. The ray of light was directed on the lateral surface of the outer wall of the scrotum under the right angle at a distance of 10 cm with a 6 minute exposure. Ten sessions were done every day. Both testes were irradiated simultaneously. The ray of light was displaced across the side of the scrotum. The sperm was taken twice a week according to the schedule. The quality of semen was determined four times by the technological system “IVOS Sperm Analyzer” (Integrated Visual Optical System for sperm analysis) of company “Hamilton Thorne Inc.” (USA) every 10 days: before the beginning of the experiment, during irradiation, after irradiation and in 55 days after exposure. The blood for morphological and biochemical research was taken before the beginning of irradiation and on the 3th day after their completion.
It was established that the irradiation with the lamp “Bioptron” of the outer side of scrotum doesn’t affect negatively on the general state of bulls-sires, morphological and biochemical parameters of blood. Stimulating effect of NPCs on spermiogenesis was manifested in increased activity, increasing concentration of 1ml and total number of sperm in the ejaculate both during and after exposure.
