We have a 3 year old Nigerian that we've never seen in heat. She spent 45 days with a buck last fall. We never saw her get bred & she never kidded. We've been told that she's probably cystic but what's treatment protocol? We had a doe 2 years ago that constantly came in heat & we used cystorellin & lutalyse but I don't remember the protocol, if it's even the same.
