Description
Summary:It is the first time in Lithuania that practical application of semen filtration by Sephadex G-15 for the needs of artificial insemination industry was assessed. The efficacy of semen filtration was assessed applying a battery of sperm quality assays to study bovine spermatozoa quality before and after filtration, as well as after cryopreservation. The estimation of effect of different concentrations of progesterone, oestradiol, heparin separately or in combination, on different functional parameters of bull spermatozoa after thawing was performed. These are the first published studies applying integrated approach to study the effects of sperm challenge with several biologically active substances.
