I have had my Alpine doe bred on three consecutive heat cycles. She just came into season again. I watched all three breedings and I'm sure she was bred. She was bred to the same buck as last year (one breeding) and this will be only her 2nd freshening. I read posts on this forum about others who have had does come back into heat after they were bred. What are the odds??? Her cycles have been very regular at about 17-18 days. The buck has successfully settled other does, so I'm pretty sure the problem would be with my doe. She is fed a good alfalfa/timothy mix hay, has access to a mineral block, is given grain at every milking and is wormed with Hoeggers Herbal Wormer once a week (as per instructions). She appears to be in good weight. Does anyone have any thoughts about what I should do?
