BVD positives thread: result, outcome, source

just do it

Just an idea for a specific thread on animals that turn up BVD positive. In particular details like:
test result value,
result of retest,
result of other animals tested particularly the cow,
did it turn out to be a PI or TI,
what's your herd disease history like,
Have you a closed or open herd,
What do you think was the source?

An excellent idea. Hope I won't be posting but we all need to join together to eradicate it altogether

also if the herd had been vaccinated

poor farmer

I have been vaccinating for the last five years .I have 2 positives so far out of 50 calves .I sent off the mothers tissue samples to the lab today.

Juniorhurler

We have never vaccinated and have 51 animals tested with no positive yet. We buy in a few replacement heifers, maybe 5-6 a year but that's all. I hope I haven't jinxed myself now with only six to calve. Touch wood.

bob charles

had about 3 / 4 last year, all bought in animals supposed not to be incalf. this year we are running at 33% + positives from all calvings (25 ish usually a year). Cant vaccinate as animals wouldnt be bought long, also cull cows turning up with PI calves. goes to show the high level of BVD on the ground in older animals, presume most of my infections are animals coming into contact with PI's during pregnancy. Sent another one today to la la land, nothing worse than hearing a cow bauling looking for a calf.

just do it

For those with positives, what kind of reading did you get? Some people have posted results but it's impossible to know if they are low or high readings. The significance of course being a low reading may subsequently turn out to be a TI.

33% ? Am I reading that correctly?
That's a serious loss. i wonder did you have the same levels in years gone by that you weren't testing for? If so then you would have had a high enough mortality rate as well as a serious lack of animal performance? Or could it be that dry cows that you bought in were sold before mandatory testing came in because they or their calves had tested positive?

We've been vaccinating for at least 5 years and have had no PI's last year or this year so far!
Started vaccinating 5 years ago because we had a calf died and when we tested him, he was a PI.

Noticed a serious reduction in calf scours when we started to vaccinate. Scour almost a thing of the past now with only on average 2 or 3 scours per year out of 60 calves.

yip 33% and I think its higher, have 2 off yesterday with BVD. Last year I think we had 3 PI's out of give or take 25 calvings. I presume some of the cows were sold because "the calf didnt thrive last year" and not in calf, others are just maiden heifers that turn up in calf and just drop a PI on first calving. I have 3 live calves from the first dozen or so calvings this year. Aslong as I have alive cow after calving I'm not overly concerned but its a kick in the nuts if you worked hard to bring a calf, get it to suck, spend a week checking it and then shot it a week later

just do it

Well hopefully this eradication scheme will make it a thing of the past. Of course that will depend on the actions taken in the next year or two against those who don't comply.

Do you think allot wont comply, as in hold onto the PI's and hope to get them to slaughter

I was just going to ask how can you not comply? Bob you are having bad luck, buying in other people's trouble.

pakalasa

I sent away 2 ear notch samples to Enfer on Tuesday. Both cards arrived yesterday, Wednesday. Quick or what?

Yes. There are still some farmers not fully aware of the 'why's of the scheme. They know the 'what to do's of the scheme but not being aware of the reasons behind it will be less than 100% thorough.

Holding onto PIs while not illegal allows the possibility of more PIs being generated.... in the initial pilot projects that were the research for the scheme a lot of the PIs identified were bought and paid for... heifers in-calf with a PI calf that were bought in. How do these heifers get in-calf? Some will be unintentional, perhaps with their own cohorts but some through dangerous liaisons with the neighbours stock. Now if the neighbour is trying to rear PIs to factory weight......maybe as bulls......... :eek:

I'm thinking lads that won't send in samples

Can I ask what do you vaccinate with and at what time of year?

Rispoval intrasal, bovispast etc????

Bovillis BVD or Bovidec BVD.

Administered to the breeding animals before going out with the bull or serving with ai. They have to get 2 shots of it the first year and every year after that then just 1 booster.
