The Repro seminars I have attended told us frozen can be?expected to live for?12 hours after implantation.? The 2 repro vets I have actual experience with, do the implant in the high teens.? However, one of them has successfully done them in the high 20s.? And, I perosnally know of a breeder whose vet?did?one in the high 30s, and the bitch whelped a litter of 10 pups! I have spoken with many vets about ovulation timing, fresh and frozen implantation, and the different opnions are amazing.? I have even had the vet on the sending end, and the vet on the receiving end, disagree!? It's a wonder any of the bitches get pregnant.

The Surgical Implant should be done when her progesterone numbers are 20 to 22 with frozen. Fresh chilled semen lasts about 5 days.....you do the implant when numbers would be anywhere from 10 to 16 typically........couple of days after 5.5 or 8.5 "assuming" it will be at the higher numbers by then. Personally I wouldn't advise using frozen semen on a "weird" season................<G> Carolyn marhaven@xxxxxxxxxxxxxx www.Marhaven.com Hi Louie: My experience with progesterone testing and frozen implants is we keep doing progesterone testing until the number is in the high teens.? It is possible she really didn't ovulate the first time, and is having a split season.? You would have needed at least one more progesterone test to be sure she kept rising past 10.?? I would be interested in hearing what your repro vet has to say.

One of my Champion bitches is having weird seasons. Her seasons have been normal until 7 or so months ago. she came in season (normal season) went out for 4 or 5 days and came back in season again normal season. Didn't think much about it and just thought it was a freaky season. 7 months later she comes in season and we are going to breed her using frozen sperm (normal season)we thought. progesterone 1.8 then 5.3 then 10. ? (I forgot) the Vet. then did surgical implant which from the first day I saw blood to implant was 22 days. 4 or 5 days later she comes in season again, today smear was done and progesterone taken and is @ 5.6. A blood sample was sent to lab last week to A&M and waiting results. Doing another progesterone test tomorrow. Vet (reproduction specialist) best in this part of the country be back in town Mo nday. Not sure what is going on yet. Any one ever came across this situation or have any comments. Thank you. Th e list is great. ____Louie ============================================================================ POST is Copyrighted 2008.
