Im a row-crop farmer, but i have been told that you sleeve a horse vaginaly and you sleeve a cow through there rectom.. iv been told, not making any promises but thats a start i guess
Luke is right, you check cattle through the rectum; however it would be advisable to seek the help of a vet. For the slight cost of having a vet do it, it will likely be well worth the accuracy.
The normal way is through the rectum but I would advise a vet to do it to make it more accurate also you can now preg check cows by taking a blood sample and also the expensive route of an ultra sound lot of the big dairies are using blood testing or ultra sound due to the fact the can preg check at 30 days bred rectum is best at 40 plus days though I have seen the more talented vets have been able to check at 30 days but most of the time it would be a recheck.
Is there a site for the company?
ABS was able to do the blood test or send it in around here. If the cows are to calve in the near future, you could probably feel the calf yourself. Through the rectum. I would consider using a vet and they could tell you more of a accurate date. Consider it an investment for precision and efficiency.
