[QUOTE="regolith, post: 910447, member: 9267"] The usual synch protocol - gnrh + prostaglandin will work on aneostrus cows. I personally wouldn't recommend it for cows less than 6 weeks after calving. I've done it, on that small group of cows the closest to calving then showed a distinct tendency to irregular and missed heats. She can be mated to a natural heat at any time after calving, first heat may have a lower conception rate but in my situation it's worth sticking a straw in her even if it's only ten days after calving, maybe different if you have to get her out of the herd and get a technician in or want her to hold to expensive semen - then wait for the second cycle for a better chance.
