This semen was only 40% viable, which is about the lower limit of what you would ever want to work with. Most of what has been collected in the last 15 years is much better than that--as much as 80-90% viable. Not Drake's fault--he was siring very well when he was collected--it's just that they are better at it now.Seraphina said:Congratulations :cheers: Drakkar is on my list of favorite dogs and so it is good to see him siring another litter. I have also been considering using frozen semen, but was worried about the success rate in Whippets, this gives me little bit more confidence.
They were just getting the technique down when Drake was collected. The key is to pinpoint ovulation absolutely via progesterone, and then do the surgical implant in the right 12-24 hour window. Frozen semen may only swim for 12 hours so if you put them on top of eggs a day away from being ripe or a day too late, you won't get anything.
