This is how our market (Hereford) works. All stock has to be pre-booked, with the exception of culls. You fill in all of sections 1 and 2 of the AML1. Put the market "XYZ Livestock Market" as the destination address. Tick the box below the Individual Identification panel at the top right for Moving animals to a Central Point Recording Centre (top box). Put your flock no., then all the individual tag numbers in that top panel. All ovines must be double tagged for our market. Take spare tags and tagger with you just in case one's lost on the journey. Take a container of water and a bucket and some hay in case you break down en route.
When you get to the gate there'll probably be someone taking the form - you'll get part of it back. You could ask him if you've filled it out correctly. He'll give you a cleanse form which you have to fill in and hand in at the gate as you leave, and tell you where to unload. Once the sheep are off the trailer stay with them and look helpless. Someone will move them to a pen. You then wait with them until the market porter comes along, takes your details and another bit of the form and asks you how you'd like them sold (as a batch or individually). You then hand in the cleanse form, park up the trailer and go to the market café for an English breakfast and mug of tea.
