Has anyone ever had an outbreak of Tick Borne Fever in dairy cows?
A quick rundown on our case:
On the 20th of April, I had six first calvers with no milk and high temperatures. I immediately suspected IBR so the vet recommended that we vaccinate. Symptoms cleared up and heifers came back on 70% of their milk.
Moving on to the 20th of May, another batch of first and second calvers came in with high temp and no milk. We treated with Betamox and Dexametasone as temp were very slow coming down. The vet took dung and blood samples but before we got results two cows were passing blood and subsequently died. The remaining affected cows were much more severely affected than the last bunch. This is when test results came back showing Tick Borne Fever.
We are now in our third bout of it with roughly 10% of the herd affected. Oxtet works well but obviously it is not a long term solution. We have traced it to one area of the farm which, up to now, we have never had any problem with but it is bordering a wooded area.
We are spring calving, grazing from February to November. We can not really afford not to graze this area and it is not suitable for cutting. It is grazed bare and tight everytime. Has anyone had experience with this before and have any solution. AFAIK there is no available vaccine.
Thanks for reading and any help.
