OPP negative flock too! And Blue Tongue too!

Another 'as expected' result from the blood draw. I actually did a specific OPP test for sheep this time around. It does not give false positives (or negatives) and is highly effective in finding those with OPP.

Needless to say I'm quite relieved!

I also had my flock tested for Blue Tongue as I acquired sheep from areas of the country that have it throughout. I've only gotten the results of 25 of the 54 sheep as they are running the other batch tomorrow. The first half are all NEGATIVE as well. I will not test for this test again once I get the rest of the results(if they are negative) as here in the cold northern part of MN we do not have the vector for BT to be transferred (most of the midwest doesn't have this vector, or the mountainous areas to our west). The only way it can be transmitted is via this vector. If we don't have it, other animals cannot get it transmitted to them.

This is also NOT the same Blue Tongue that is ravaging Europe and the UK. There are 6 or more strains throughout the world. After talking to my state vet, the state vets in CA and OR and the Federal vet (who actually has a lake cabin 30 miles from my farm!) I've concluded this is not a huge worry for us in the Midwest, especially since we do not have the vector. The federal vet for BT told me that eventually the titers if present will eventually fade away. Titers just mean that the animal was exposed to it, but did not get it (antibodies if you will) is how i understood it.

It will be interesting to see the rest of the results.

Congratulations, again!!! I think you are doing a great job of leading by example in the Shetland sheepbreeding world. :-)
