Cercetări privind conservarea spermei de vier

Abstract

The research was performed on ejaculates obtained from boars raised at the State Enterprise "Moldsuinhibrid" and accepted for processing, meaning on those ejaculates which showed more than 75% sperm motility. Immediately after the macroscopic and microscopic examination semen was diluted with GHŢS and in the composition was introduced the substance of the BD-1 being produced at the Institute of Microbiology and Biotechnology of ASM in concentrations from 1 to 10%. The samples of diluted semen were stored at +4°C for 5 days. The sperm motility and the speed of sperm movement were appreciated with a 24-hour interval. The obtained experimental results showed that BD-1 as antioxidant and membranotropic is not toxic to the boar sperm in the studied diapason of concentration. The best results were obtained when the concentration of the BD-1 which was introduced in the composition of the GHŢS constituted 7% with the mobility of 24.5%, sperm with progressive movements of 8.5%, VAP of 54.6 mm / sec, VSL of 27.5mm / sec and VCL of 115.2mm / sec after 5 days of storage at +4°C.
