Synchronization Trial

Synchronization Trial
SpermVital conducted two separate field studies in different markets during 2014 to investigate whether the SpermVital semen had increased longevity in cows and heifers.


The studies comprised of a total of 491 animals (both beef and dairy breeds were included), randomized into two groups, and then synchronized for estrus.
Thereafter, approximately half the cows and heifers were inseminated on day 3 after estrus synchronization with one dose of SpermVital semen. The other half were inseminated on both day 3 and 4 with standard processed bull semen.
Normally, it is expected that insemination on two consecutive days will give a higher pregnancy rate than only one insemination.
The results showed that the Non return rate did not differ significantly.

The studies prove that the animals inseminated with SpermVital semen had equally good access to fertile sperms compared to those animals inseminated on two concecutive days with regular semen. These studies support the recommendation that one dose of SpermVital semen can replace double inseminations with standard semen. Furthermore, the studies imply that the SpermVital technology prolongs the lifespan of sperm cells
