Re: [AlpacaTalk] fertility issues
Ok, well, this girl came to my farm in December 2007. Maybe January 2008. She was bred to my rose grey boy May 31, 2008. Here's the calendar for her:
May 31, 2008 bred
June 23, 2008 bred
June 27, 2008 spit
July 2, 2008 spit
July 5, 2008, during spit testing another girl, she kushed, so we brought her intended back and they bred.
July 12, 2008 spit
July 26, 2008 spit
August 12, 2008 spit
October 9, 2008 aborted twins 96 days gestation
October 26, 2008 bred to a different sire
no spit testing.
January 15, 2009, aborted twins 82 days gestation
May 30, 2009 bred to my grey boy
June 1, 2009 spit
June 8, 2009 spit
June 11, 2009 spit
June 27, 2009 spit
July 2, 2009 spit
July 31, 2009 bred after resorption some time after July 2, 2009
August 12, 2009 spit
October 2, 2009 spit
October 8, spit
October 19, 2009 aborted twins 80 days gestation
So, as you can see, I am careful not to overbreed. Even in 2008, the second breeding was 23 days after the first, and the third breeding was almost 2 weeks after the previous one. At this point, I don't hold out much hope.
Does anyone know how to ensure that only one embryo is implanted? She obviously ovulates and implants. I have considered progesterone supplementation, but the record for twins surviving is not good, and I'd rather not have a freemartin of they are mixed sex pair.

Heather - just a thought - could her twinning have something to do with being bred multiple times since they are induced ovulators? If she were mine, I would breed her just once and see what happens.SUSAN OLSONAlpaca LocoRiverside, CA
