Yup. We're going to do a confirmatory test and cull her if she's bad. I vacc everyone for BVD yearly and tested everyone this year when we tested for Johnes. Everyone else is clean.

Get some good colostrum in it..assuming new born
DO you vaccinate?
When? Pre breeding, fall?
ML or killed? Fetal Protection?
If you use ML do you mix up alot and take over an hour to use it? Does it get out side temp hot, in the sun?
Cows and bulls?

PI calves are created in-utero during the first trimester. Exposure to the virus after this will cause the disease, not a PI. PI cows and cows exposed to the virus create PI calves in utero. Once the cow herd is clean, test the calves every year. Most labs will pool ear notch samples to keep costs down - they would only test each sample if the pool is positive. I would not keep a replacement until it was tested not because of exposure as a calf but because you have had it on your place, it can persist in the environment for awhile, and no vaccine is 100%.
