Had 39 (37 hfrs, 2 cows) head set up for this past weekend. Used the 7 day CIDR protocol. GNRH + CIDR, pull CIDR a week later give a shot of prostaglandin. We heat detected and AIed on schedule for 3 days giving a shot of GNRH at breeding. At 72 hours post CIDR pull we bred 7 heifers that showed no sign of heat and gave them a shot of GNRH.
One cow displayed heat but was never standing, the other cow I noticed stringing but never displayed any other signs of heat and was a royal pain in the butt to breed, never could get to the cervix, she would stand all hunched up and with so much pressure there was no progress. Two of us tried her to try to salvage a $40 straw but to no avail I highly doubt she conceives AI. She was a pain last year as well so I will no longer be wasting my time trying to AI her.
Want to know if anybody has a strong opinion on length of needle used when injecting the sync drugs. Guy we had set them up used a 16 gauge 1" needle and I didn't feel like it was adequate, I prefer an 1.5" 18 gauge. With only getting 30/37 heifers to come in I am looking for explanations as to why we had such a high percentage not exhibit heat. The majority didn't really feel like they were in heat by the texture of their reproductive tract either so I don't think it was a miss in detection I just think they flat didn't come in.
