[QUOTE="Fire Sweep Ranch, post: 1483118, member: 18809"] Since fall breeding season started, we have AI'd 18 head, 17 stuck the first attempt (all natural heats). The one that did not stick the first time passed over on the second breeding. Her cervix was very small, and just a bump. My oldest daughter bred 15 of those (including the one that came back in), the middle daughter bred the other two (and stuck the heifer on her second heat - her sister could not get through the cervix, so she handed it over to the middle daughter and she did it!). Now, in contrast, I set up 7 cows with a CiDR for embryos. 6 clustered tight enough to take to the vet to get embryos (the 7th got an embryo two days later, and stuck it). Only two of the six stuck embryos, and one of those two absorbed her pregnancy at 60 days bred (she has been AI bred, will be 21 days next weekend). The 4 that did not stick got a second embryo, only one of those stuck. We AI'd the remaining three the third cycle, and they stuck. Natural heats and good heat detection are critical to get those kinds of results. It is done all over, most people do not brag about it. Dairy cattle are a totally different story; high milk production in a stressful environment is not helpful. [/QUOTE]
