That sounds interesting, cert. Only thing we've put IN is 60 to 120cc's of oxytetracycline 100 (or occasionally 200). No milk withdrawal, interestingly enough. No idea on meat withdrawal time or lack of.
Jeanne, I've seen a lot of folks suggest leaving them alone, and I have to wonder if perhaps things are different for dairy cattle vs beef cattle? With these dairy cattle, we'd never consider leaving them alone for 7-10 days before trying anything. Had one come through the barn this morning with diahreaa, and boss checked her for a uterine infection. Yep. I think it's been 3 days since she calved. We infused her, hit her with Excenel and Lutalyse - last cow we had that showed up like this...died. (I'd say secondary complications due to uterine infection - fresh cow with diahreaa from internal infection turned into rumen not working, and, as she was overconditioned at calving, probably also complicated by fatty liver and ketosis. Still, I don't think being ketotic killed her; I'd say it was due to her rumen no longer working.)
But then dairy cattle tend to be under a lot of stress - calving, change in feed, high milk production, etc - things that are so much greater than what your beef cows go through following calving. I haven't ever heard a beef person on here say anything about a cow having a retained placenta following calving and then be checked as "open" or with an infection that fall. But a dairy cow with a retained placenta...uterine infection almost guaranteed, and I've seen them keep that infection for months. Won't get rid of it without help - generally 3 shots of Lutalyse clears a chronic infection.
