[QUOTE="regolith, post: 630425, member: 9267"] You're doing something right. I don't use CIDRs, just the GnRH and prostaglandin (ovsynch programme). Did 19 cows last year. Three of them came on heat early - AI'd those. Timed AI the other sixteen - a different technician did them because I couldn't be bothered doing 20 in one hit. Two of the first three held. Two of the sixteen held to their mating (about half show signs of heat that day). Three of the three naturally cycling cows AI'd along with those sixteen held. I've had bad results every year from synchronising. Still do it, because they get in calf second or third time round - better than not getting in-calf at all. [/QUOTE]
