A Taste of Life at Windrush Alpacas

Another Success – of Sorts

In an earlier post (see post June 9, 2008) I had mentioned that Theresa, one of the alpacas who is boarded with us, had a retained CL that we were treating.  Theresa had fooled us into believing she was pregnant and after over a year’s wait we realized that she had a retained CL that made her think she was pregnant.


We started treating Theresa with Estrumate to help her release the CL and cycle again.  The first treatment had an effect on Theresa but not the one we were looking for.  The Estrumate seemed to make Theresa feel that she had delivered a cria and she stole Ivanna’s cria Zianna.  Zianna (who is still to be introduced on this blog) was quite happy to spend her day with Theresa, but Theresa didn’t have any milk and Ivanna wanted her cria back and so we put Theresa in with a group of young alpacas we were weaning. 


Not having had any success with the Estrumate treatment we repeated it a week later, Theresa continued to reject the male indicating to us that the retained CL was still retained.  We consulted with our vet who suggested that we wait another week and try the treatment again.  If that was not effective we would then need to consult a reproductive specialist.


We gave Theresa the third Estrumate treatment and finally this past Saturday she cushed for our male alpaca Zin and allowed herself to be bred.  Zin who usually breeds for 20 minutes bred Theresa for 40 minutes.  We mentioned this to our vet when we were at his clinic for the ultrasound appointment and our vet said that all of the Estrumate Theresa had received might have had an effect on how she smelt to Zin encouraging his marathon breeding session.  Thinking back I had noticed that Zin had been glued to the fence line for most of the week, gazing longingly over at the girls pasture – perhaps all of that Estrumate really had put love in the air!


On Tuesday while we were breeding some other alpacas I noticed Theresa walk over and cush in front of Zin’s pen indicating that she still has not cycled or conceived.  Having noticed Theresa’s behavior we decided to breed her again yesterday which would be three days since the last breeding.  I fully expected Theresa to cush immediately Zin entered the pen, but instead she spit at him, screamed in his face and then cushed.  This is not normal for Theresa, she is usually pretty definite in her reactions and to me her reaction to Zin was a bit of a mixed message.  Zin bred her for 20 minutes this time, during which Theresa remained cushed and seemed very comfortable.  Still though a question hovers in my mind as to whether she really has not cycled or whether the Estrumate now has her confused as to her reproductive state.


We are going to wait several days before testing Theresa again to allow her body a chance to decide what it really feels.  Should she cush again for Zin then we will take some different steps to ensure that she does not have a uterine infection before we subject her to another breeding.  An alpaca breeding is quite hard on the female’s reproductive tract and we would rather take things a little slower and make sure Theresa is healthy than over breed her and possibly cause more damage than good.


And while we figure out what to do with Theresa young Zin will have to spend his days gazing across at the girls pasture acknowledging the fact that as far as a breeding male alpaca is concerned love is in the air and just a pasture away!

  1. Interesting story. You sound like quite a romantic . . . love is in the air just a pasture away. I definitely got a chuckle out of that. 🙂 Kel
