Development of Long-Trem Strorage Technology for Male Boar Semen at 1618 C

Elena Cibotaru, Darie Grigore

Abstract: The our aim of the research was to test the PSS preparation obtained by the Institute of Micribiology of the Sciens Academy from Moldova used as an additional component in dilution medium for boars material semen.The positive results of the research obtained prove us that when we use the PSS preparation in the dilution medium as an additional component with a concentration of 7%, we obtained a good results in conservation of material semen to the 16–18 °C after 96 hours of conservation with the mobility of the spermatozoons was 54,3%. For the first time the capacity of PSS preparation was proved the specific and nonspecific ability to grow the resistence of conservation at 16–18 °C. It was studied the speed of movement of the spermatozoons during the concervationof the hypotermale temperature. It propose the dilution medium and conservation to the boar sperm at the 16–18 °C of temperature and that contain: glucose, sodium citrate, helaton, amonium sulphate and PSS. To applying this medium allows to use more efficient the value of boars in the reproduction and in the artificial insemination.

Keywords: the boar, sperm, dilution medium, speed of movement, conservation, hypotermal tempreture.
