Understanding the Numbers

Cliff's proven frozen semen has a guaranteed post-thaw minimum of 78 percent total motility and 68 percent progressive motility. Cliff's numbers far exceed the industry standard in which a minimum of 30 percent  progressive motility should be present post-thaw for a stallion to be considered a ‘good freezer’. The Colorado State University Equine Reproduction Laboratory handles all the collection, processing, storage and shipping of Cliff's frozen semen. This ensures high-quality, reliable production control for all Cliff's mares.

Is Your Mare a Good Candidate for Frozen Semen? 
Some Things to Consider

Is your mare a proven broodmare that is easy to settle?  Then she is the very best candidate for frozen semen. Maiden mares and older mares (who are reproductively sound) can be bred successfully with frozen, too, as demonstrated by several of Cliff's mares. 

Does your reproductive vet have experience and a proven track record using equine frozen semen? If not, is there a vet near you who does? Or is your vet willing to commit to do what is required to follow the protocol?

Does your reproductive vet have the facilities and staff to monitor your mare for the optimum timing of insemination? This just makes life easier for everyone. If not, are you and your vet committed to do what is required to follow the protocol?

Are you willing to take the necessary steps required for increased mare management? This includes additional ultrasounds to help pinpoint the best timing for insemination, whether using one dose or two doses of frozen semen. If following the protocol for two doses, the first insemination is within 12 hours before ovulation; the second insemination is within 6 hours after ovulation. If just using one dose, insemination must occur as close to ovulation as possible but not more than 6 hours before or after ovulation. Timing is everything when using frozen semen!

Are you willing to start working with your repro vet early in the year to ensure that your mare is in optimum breeding health and ready to begin 
breeding with frozen semen in the spring, so she has the best chance to settle the first time? (This is a good plan even if you are doing live cover or using fresh cooled semen.)

Whether by live cover, shipped cooled or frozen, breeding a mare is not a cheap endeavor. Skimp at the beginning and you will pay more in the end -- maybe with no foal to show for your effort and money. So do yourself,
your mare and your pocketbook a favor: Commit to be prepared and to do the right thing at the right time -- with the help of the right veterinarian -- for the best outcome: a foal of which to be proud.

The beauty of using frozen semen is that it can be ordered at your convenience with a longer delivery date -- to save shipping fees -- and ready
when your mare is ready. Gone is the anxiety of ordering a collection and praying that it doesn't arrive too late or too early, depending on how
long your mare hangs onto that egg.
