COMPARATIVE ANALYSIS EXECUTION ON FREEZING PRESERVATION EFFICIENCY OF STALLION SEMEN STORED IN VARIOUS PACKS
This article highlights the experimental research results of comparative analysis execution on freezing preservation efficiency of stallion semen stored in various packs. Medium freezing preservation speed of stallion semen in 5ml volume insemination tubes proved to constitute 4,2°C/min by 'Kryotrop' apparatus application. Temperature ranges from 0°C to minus 10 °C. Approximate freezing preservation speed equals 23,7°C/min within temperature range from -10 °C to - 80 °C. The proposed freezing preservation method of stallion semen in the insemination tubes considered to secure thawed cell formation. Motility rate forms 3,38±0,18 according to adopted grading. The above-mentioned motility rate corresponds the standard for freezing preservation operation execution in the granules and 0,25±0,5ml volume pallets. Efficient adaptation technique was elaborated for stallion semen equilibration in 'Kryotrop' apparatus by temperature +2-5 °C. The method was developed on the basis of supplementary block application.
