[QUOTE="Jeanne - Simme Valley, post: 1600663, member: 968"] I totally understand what you are saying. And, I use the CIDR's also, but was giving people options that aren't so expensive that work. A cow will NOT cycle with a Lut shot unless she is actually ready to cycle. She will not respond to the shot if she hasn't already developed a CL. With CIDR's, they will show a standing heat, but may not release an egg. I don't mind heat detecting. Actually enjoy it and I have the time. The main sync-ing I do is to get my group of replacements cycling in a 6 day window before I go on vacation. I have heats on most all heifers prior to breeding dates. So, some will come in natural heats during the 6 days, some I can Lut to get them to come in during the 6 days, and some I put CIDR's in. I cringe when I have to put expensive semen in one that did not show a heat and use TAI. I generally change up my records and pick a different bull - cheaper. [/QUOTE]
