The field trial, performed by the Ambrovet group, was based on 2076 inseminations and showed that inseminations with SpermVital® semen increased the pregnancy rate by 8,4% on average.
SpermVital® conducted a field trial in Italy during the summer and fall of 2012 to test the effect of the SpermVital® technology utilized on the Holstein breed.
The conception rate increased on average from 33.5% with regular semen to 41.9% with SpermVital® semen. The difference in conception rate increased with the number of inseminations needed. The difference in conception rate was 10,2% between SpermVital® semen and regular semen on cows needing more than 3 inseminations. These results show that cows that return to heat increase their conception rate greatly by utilizing the SpermVital® technology.
2076 doses of semen were used in this blinded field trial, where half of the inseminations were made with Holstein SpermVital semen and half with regular Holstein semen. The Holstein cows were inseminated at normal time, which is not the optimal time for insemination to achieve full effect from the SpermVital technology since it will not capture the ones with early ovulations. Normally you will inseminate a little early when you are using the SpermVital technology to achieve all the benefits the technology has to offer.
The difference between the groups are statistically significant.
The pregnancy check was performed by ultrasound.
