[QUOTE="moses388, post: 1746224, member: 27368"] Did you run any tests this year? I have seen the same thing. I lost some to scours and others pull through. I sent a couple samples to a VDL. Both positive for Rotavirus Group A. I agree with other comments - The best way to prevent scours is vaccinating the dam during pregnancy. I try to, but it does not always get done. Nesikep recommended ScourGuard and I prefer that over ScourBos. ScourBos is thicker and harder to inject. My understanding is with either vaccine you need to be in a window. Too early in the pregnancy and you might lose effectiveness. Too late and you may cause premature birth. When I put the vaccine window over my calving window of 90 days, things do not always line up. When I have a chance to do shots, it ends up being too early or too late for some cows. I vaccinate newborns with Zoetis Calf Guard, but it seems like it did nothing this year. I was reading I can use Calf Guard on the dam within 30 days of calving. I have a backup plan next calving season. Springing cows that did not receive ScourGuard/ScourBos will get Calf Guard.
