Nina Bradu

Abstract: Abstract: The work was performed as part of research on the development of new media for dilution and cryopreservation of seed of sheep in order to create a bank of producers of domestic and imported breeds. The studies were performed in a production environment. The object of research was the sheep of different breeds, which are kept on one of the breeding farms. As an experimental component of the medium was added a BioR preparation, having membrane-protective properties. Was determined the optimal concentration of the BioR preparation, which promotes motility of sperm motility and survival
after their defrosting. During the experiment, conducted research on the effectiveness of the use of new media for the artificial insemination of sheep, which showed high effectiveness. As a result of insemination of 67 sheep, in 32 of them repeated rut was not observed, which amounted to 47.8%.
Thus, was developed a synthetic medium for cryopreservation of semen of rams producers, which contains: glucose, sodium citrate, glycerin, egg yolk, BioR and antibiotics (Patent 4513), which allows to increase the performance of artificial insemination of sheep.
