I've been hit with an unfortunate situation and need advice. My AI tech is injured and can not AI this spring. We have a few more to go and wonder what is best. My ABS rep can do it but would like them synced to make one trip (TAI). Here's the deal on the cows:
2 - were set up for embryo implant 5/16. They had cyst on ovary and were rejected. GnRh was injected.
2 - are first calf heifers 40 days plus post-partum. I tried something by Cidring to get them to jump-start cycling but did not breed. Intending to Lute 11 days post-estrus from Cidr and then breed on heat detection. They cycled off Cidr 5/10.
Scenario #1 - Lute all 4 around 5/25 and schedule TAI 5/28. This will eliminate repeat Cidr protocol, but will they TAI off just Lute? I may use Estrumate.
Scenario #2 - Cidr all 4 again around 5/21 with TAI 5/31? Are there any negative affects in repeat Cidring 3 weeks after first Cidr protocol? All 4 would be Cidr'ed 11 - 13 days after last heat.
My objectives here are first setting them up for the ABS Rep to make one trip. Second, trying to stay in a March calving period. I have a clean-up bull to catch the misses, so they're being AI'ed just once. Really appreciate your feedback. Be honest, but not too brutal!!LOL
