That's a good question. But you can say the same thing about any Dry Blend, just because its dry it doesn't mean its exactly what it says on the tin, your wheatfeed, maize distillers, rapemeal etc. are just as variable as your brewers grains, processed bread or Syrups. I've tested plenty of samples of all the above. All these feeds are rigorously tested. Companies cant get away with miss labeling products anymore, they will get hanged for that.Yes it is just, on a DM basis. But are those moist blends really 13 or 13.5 ME? Sounds to good to be true
The only true measure really is proof in the pudding and the response in the cows is the proof i find. I would say that about any feed. But concerning these moist feeds cows respond very well to them, improved fertility is usually a direct response not only from the feed but also from the increased intakes.
