I would also like to hear what your vet says about the BVD and BVD - PI issue. I am in total agreement with Ken on this one for sure. I have been involved with testing my calves for BVD-PI (necessary to show & sales) and once they are tested clean, they are clean for life - never need testing again. So, that doesn't mean they will never get BVD in their lifetime, but they will never be a Persistantly Infected animal. NEVER
I agree with all that.
They can contract the disease at any time, especially in breeding stock if not vaccinated.
My rememberance isn't always the best but the two issues Ken and I haven't come to concensus is ........
1, killed vaccine give the same protection. ( I think that is his stance)
2. A cow can have BVD and get over it. I think this may be partially true but they are always a carrier and if not vaccinated can produce a PI calf.
That is what I remember. As my Dad always said, " I'm not always right but I've never been wrong."
