To qualify for the Morrisons scheme you must be Farm Assured.
See:
http://www.morrisons-farming.com/woodheads-livestock/traditional-beef/A friend of ours tried to get the local buyer interested in his Shetlands - but although Shetland is on the approved list, the buyer didn't want to know - only interested in volume even for this scheme.
This may be a local thing here in NE Scotland and the scheme may be run differently eleswhere.
