Out of interest what kind of yields are you after? I’m possibly out of touch with it as its been a while since we attempted to graze properly. But it seems a big lump of stuff to be feeding for someone wanting to get a lot of grass into them.It would be probably 40% maize gluten, 30% maize and 30% soya hulls
I can probably get away with 12kg of that as nothing is very fizzy
So would work out to be 5kg maize gluten and 3.5kg each of maize and soya hulls to the top cows
