I mean leaving all the gates open. Down here it's mostly small fields from 2-10ac generally and I know a few chaps who just let the stock roam as they see fit. So they do and they pick what they like out of every sward and leave the rest. Any bramble bush gets a foot wider every year. Every nettle, thistle and bracken patch gets a little bigger every year until you end up with places they just don't bother going every year. Then it needs major action to get it back into shape. I think the reason is probably lack of water in all fields but many of them have almost ready made mob grazing set ups with a few fields maybe needing halfing now and again. I assume the sub is worth more to them than actually maximising forage / stock performance.What's that?
