Accelerated is not producing sexed-semen. Bovatel is "gender-biased" semen. Meaning that there is a 10% greater chance of having a heifer calf than a bull calf. They have not, and probably will not sell sexed semen due to the cost of production. The technology is expensive.
Select Sires is the only company "pushing" sexed semen in the dairy market. They have a stronger market than other companies and have spent the money for the equipment to produce sexed-semen. Even then, I deal with a heifer development lot that is exclusively dealing with sexed-semen, and they are having to bred 50% of the heifers twice.
Talk to honest rep's, they are not going to sell sexed-semen to most producers. Conception on "cows" is better than virgin heifers, from trials that are recorded. Thats because they "know" the cows are cycling. Alot of trials have been done on heifers, but data is failing due to no synch which means they are not positive that heifers are cycling.
