We have this 2015 show heifer that we cannot get bred. We have tried A'Iing, then pasture exposed bull, had her palpated (after running with bull 2 heat cycles) was cystic (vet took care of this) plus vet said ovaries on one side were immature/underdeveloped but the other side ovaries were perfectly fine and ovulating and used time/sync ai'd breeding with her no luck came into heat again this past week and is out with bull again. We saw him mounting her in standing heat. If she comes into heat again, is there anything else we could try? Would it be wise to pull her up now and watch, if she comes in heat give another shot of cystorelin and turn her out with bull again or wait and timed/sync AI again? I know some will say ship her, but before we do this I would like to exhaust all avenues... she has been a really successful show heifer that we don't want to lose.....right now my only cost is shots given and labor. Thank you for any help!
