It is new research that is discovering reasons for early embrionic death, genetically. It is timely because I had a 3 year old angus cow come into standing heat yesterday morning, after being AI bred for 99 days. I have beat myself up trying to figure out what went wrong, but in essence will never know. She has quickly gone from a September calver to a (hopefully) December calver. The embryo implants at around 70 days, so did it never implant, and it just took her awhile to cycle back? Also, we had a recip that came back in, after reaching 48 days bred. We put another embryo in her and she is 49 days pregnant today. I had a heifer that we AI bred for the first time, who normally cycles at 19 or 20 days, but came in at 23 days post her first AI attempt. Was that early embrionic death, or just a late cycle?
Most people do not watch their cattle heat cycles like we do. If a cow checks in as late, or even open, most never question. This research may shed some light on early embrionic death, and, in the future, make attempts to avoid some of it!
