How were your results? Positive or negative?
The manufacturer claims that HEIFER-PLUS kits provide at least 20% increase in female calf rate when they are added to the straw during the thawing process. However, we can't get such a rate in 100 cows. Female and male calf rate were found as 45% and 55%, respectively.
This is a friend of mine, Victor has worked a lot with Heifer Plus in AI and Embryo transfer. https://www.researchgate.net/profile/Victor_Di-Bella_Rincon/
Regards and good luck
Looking at the Heifer plus website I would have to be skeptical based on the low numbers they present in their trial - just a total of 156 heifers split over 5 trails. This is not really enough to be convincing. They would need to have data on a few thousand animals...

We routinely collect semen from rams. We will be glad from collaboration with you if you interest ram sperm.

We would be happy to work with you. Do you have the ability and equipment to determine gender? Is there a market for ram sperm?
Henry
Unfortunately, we have no equipment to determine gender? There is a limited market for ram sperm in our country, Turkey. Thank you again.
