RESEARCHES CONCERNING THE INFLUENCE OF THE BIOACTIVE SUBSTANCES ON THE BOAR SPERM PRESERVATION

Elena Marandici, G. Darie, P. Chintea

Abstract
The experiences were held on the boar sperm. There were studied the bioactive substances with the role of antioxidizer made at the Institute of Genetic of Science Academy of Republic of Moldova. The bioactive substances (PGL-1) were used as a structure dilution GHTS what is used for boars sperm dilution with the concentration of 0,1 - 1%. The experimental researches showed that the studied substances were not toxic for sperm used in the structure of GHTS dilution with the concentration of 0,1-1 whit gave the possibility to increase the period of boar sperm stoking till 168 hours, keeping the sperms mobility at the level of standard of artificial insemination.

Key word: Boar, sperm, dilution, motility, concentration, bioactive substances, antioxidizer

Rezumat
Cercetarile au fost efectuate pe sperma de vier. În studiu au fost luate substante bioactive cu rol de antioxidant, produse la Institutul de Genetica al Academiei de Stiinte a Republicii Moldova. Substantele bioactive (PGL-1) a fost introduse ca component al diluantului GHTS destinat dilutiei spermei de vier în concentratie de 0,1-1%. Rezultatele experimentale au demonstrat ca substantele studiate nu sunt toxice pentru spermatozoizi. Introduse în componenta diluantului GHTS în concentratie de la 0,1-1% a dat posibilitatea de a mari durata pastrarii spermei de vier pâna la 168 ore, pastrând mobilitatea spermatozoizilor la nivelul standardelor spermei destinate însamântarii artificiale.
