Breeding Sheep

About Scrapie Genotyping

Breeding for resistance to this horrible disease is effective. In 2008 there were no clinical cases of Scrapie in 2014, however surveillance has recently confirmed a VRQ/VRQ case, and so continued monitoring and testing is prudent. It could take just one ram with a bad genotype in one particular breed to reverse this trend and undo all the good work.

We asked our Innovis Technical Team about Scrapie Genotyping...

Why should I continue Scrapie Genotyping?

• Scrapie is a serious sheep disease – it’s under control now so let’s keep it that way!
• Considerable progress has been made in recent years despite the lack of interest from ram buyers. Don’t give up just because your customers may not be interested – your industry needs you.
• Flock owners who have had a Scrapie problem in the past will not want to buy susceptible stock
• Animals destined for export must either be part of the Scrapie Monitored Scheme or Type 1 genotype

How do I take the samples myself?

The Innovis pin pricker kits make sampling from the muzzle of the sheep much easier than the previous method. Make sure that the muzzle is clean of dirt and mucus before taking the sample. Press the pin pricker against the muzzle and then relax the skin to help the blood spot form. The blood spot can then be collected onto the absorbent pad. Full instructions are provided with each sampling kit and our technical staff can talk you though the process should you have any difficulties.

Why don’t I need a vet to verify the sample anymore?

Once the blood spot is on the FTA sampler it will be stored by the laboratory for at least 5 years. This means that the authenticity of sample can easily be checked in the case of any future dispute. Breed societies may carry out random sampling at society sales to audit this process.

Once the laboratory has received the blood samples, Scrapie results should be back within 10-15 working days. If you need results for a society sale please send blood samples in at least 3 weeks before.
