was watching this and i know my view is different but i will put it forward anyway.
i think nutrionalist get caught in a trap of not looking outside their normal ingredients. bit different but looking at sheep rations and have seen quite a few with great labels and second rate ingredients brought up to spec with megalac and stuff. so have went with an oldstyle mix. 70% is cereals-barley, maize and soya(over 20% soya) rest is molasses etc and it is nut form. cheaper than the other mix but same output from ewe.
it is the view we take here that meal needs to be basic, after looking at old labels i have noticed that the best meal was once a made with all better straights, now it has plenty of profit in it.
what is the feeding value of oats as to barley, was thinking of them for lambs for finishing in late summer.
