This thesis deals with the launch of SpermVital, a new revolutionary technology which prolongs the lifespan of semen, in Austria. In the autumn of 2015, the Genostar Rinderbesamung GmbH started to sell the SpermVital technology to both dairy and beef farmers. The farmers in Austria will finally be getting the advantages of the SpermVital technology with increased flexibility and the ability of grouping inseminations together. The SpermVital technology will also help increase the pregnancy rates on repeat breeders. The advantages for the farmers are examined in this thesis.

The NRR 56 of standard processed bull semen was compared with the NRR 56 from SpermVital semen of agricultural operations, which intensively used SpermVital. The collected data were compared in a period of three months.

In a second step, the NRR 56 from SpermVital – insemination was compared with the average NRR 56 from Fleckvieh Niederösterreich.

The results show that SpermVital have at least the same fertilization results as standard processed bull semen. No potential improvements in the results have been found. The problem is that farmers use the expensive SpermVital technology for cows which have fertility problems. A correction for this problem is not possible because of the small data volume and that fertility is influenced by many factors.
