[QUOTE="wbvs58, post: 1803816, member: 16453"] In the time I've been on CT I don't think I've read one thread where BVD has been a problem. I'm sure GB or Butch will dig some up to prove me wrong but I have mentioned it as a possibility many times with small runted calves but it is always discounted as a possibility. Is it because people like to bury their heads in the sand about it. In Australia we don't have the live vaccines available mainly due to the fact that our senior government Vets have a hang up allowing them as it may affect the serology testing, a bit of a hangover from our successfull eradication of Brucellosis in the late 1970's when bangs vaccination was discontinued so cattle were tested and slaughtered the +ve's. Vaccination of cattle is poorly taken up here mainly due to the cost and need to muster twice for the initial vaccination so most big producers just live with it, some try to run PI's with their heifers prior to joining but because it is endemic there is little obvious loss. The big losses tend to occur in herds that an attempt is made to keep them clean and then they get a PI introduced and so have a problem for a year or two untill it is endemic. So I would say the cost and not seeing an obvious benefit is why there is little uptake of vaccination. Ken [/QUOTE]
