So, due to some bad management practices that I have since corrected, I now have a sterile boer doe. I want to share my mistake so that others know to avoid the circumstances that caused this loss in my herd. Last summer I had very limited fencing and because of this I had my sheep running with my goats. I also keep my ram with my sheep year round and let them lamb whenever they want, which due to naturally occurring synchronized heat cycles means they all lamb at the same time twice a year. No problems there. The problem lies in that rams are very happy to breed any goat who will tolerate it. I had one doe in particular who had the hots for my ram. She would intentionally, yes intentionally, get her head stuck in the fence and let the ram have his way with her. Then when he was done she'd pull her head out like it was never stuck. Consequently she became pregnant by the ram twice and, the way it goes, had miscarriages both times. Since then I have made improvements to my fencing program and eliminated this from happening anymore. Unfortunately now though she has had 2 miscarriages with the buck covering her. She was rebred yesterday but if she miscarriages again she will have to be culled. Do yourself and your does a favor and keep them rams locked up away from your daughter, I mean does.
