Stallion semen cooling using different types of extenders

Popis výsledku v původním jazyce

Due to the advantages it offers, artificial insemination is an important part of current horse breeding. One of the limiting factors influencing the use of cooled insemination doses is the decrease in sperm survival over time, which can be influenced by selected extender. In our work, we focused on samples of insemination doses of Warmblood stallions diluted with a skimmed milk-based extender, INRA 96 and BotuSemen Gold extender stored at a temperature of 4 oC for up to 72 hours. Of the selected diluents, the skimmed milk-based extender reached the lowest values of total and progressive motility for all stallions and the lowest values of morphology for two of them (p &lt; 0.05). Differences between INRA 96 and BotuSemen Gold were in sperm motility for one of the stallions, with INRA 96 reaching total motility of 53.66% and progressive motility of 17.13%, and BotuSemen Gold reaching 63.71% and 23.01% (p &lt; 0.05). For two of the stallions, INRA 96 reached the highest values of sperm viability (p &lt; 0.05). The skimmed milk-based extender, the advantages of which lie in its practicality and affordability, achieved lower values of the quality parameters of equine ejaculate than diluents with a chemically defined composition INRA 96 and BotuSemen Gold. There were differences between stallions in used extender. To maintain the best semen parameters, this should be taken into consideration and extenders should be tested for each stallion before the actual distribution of insemination doses to breeders.
