VACCINE
A trial has been carried out in SHEEP where they were given BTV8 vaccine at the same time as Heptavac P, 3 weeks before lambing, and also for another group, 3 and 6 weeks before lambing. In both cases colostral antibody was still strong at 14 weeks of age. Further trials then indicated that vaccination take in lambs is NOT affected by the presence of maternal antibody
This demonstrates that BTV vaccine can be given at the same time as a clostridial vaccine, and indeed I understand that it is now accepted that in both sheep and cattle a number of vaccines can be used at the same time as BTV8 vaccine without affecting the efficacy of either. I will let you know the full list in due course. However in GOATS the work has not been replicated, and I will take advice from the manufacturers on that point. Meanwhile, given the comparatively poor ability of goats to respond to several vaccines, it would seem sensible to follow the “not within 2 weeks of another vaccine” rule wherever possible until or unless it is proven not to be needed.
When it comes to goats we still have the stumbling block to movement that vaccination in goats is not recognised as there is no caprine MA for any vaccine. The licenses for moving ruminant livestock from within a PZ have suddenly vanished from the DEFRA website. I will follow this up, as without that page, we have no way of guiding anybody anywhere.
