Tricks of the trade: DNA Testing

Written By Rachael Gawne

DNA testing is in full swing and will continue to be over the lambing period. Making sure your data and samples are done correctly is vital. 

When sampling: 

  • Aim for the centre of the ear.

  • Double punch the gun to ensure the red stopper has sealed the TSU correctly.

  • Use TSU's in chronological order - should anything go wrong this can make it easier to identify where.

  • Use the TSU blue racks to store samples once they have been taken.

When posting:

  • Ensure your samples are posted in a very secure padded post bag or box.  

  • Envelopes are not suitable for posting TSU's

Being organised and having good procedures in place when sampling makes all the difference
