This is my time trying to breed my mini alpine. I have a 1 year old mini alpine that comes in heat and stands for my ND buck. However after several times (3 separate heat cycles) of being bred it doesn't seem that she is bred. I know that the buck is not sterile as he has bred my other ND does. He is also tall enough to reach. Just wondering if anyone had difficulty breeding this bred and any other suggestions would be helpful.
