At least I've got you guys looking at tags!!!
Don't want to put words in Denny's mouth but I think he meant
the mineral he mentioned was like "dirt in a bag"...in other words,
they don't amount to much.
As for the 'corn distillers dried grain with solubles' there is only
enough to keep the yeast active. When mineral contains 'grain
by products' it will get hard when wet. Vigortone stands up to
weather very well. No grain to clump or sour. If Vigortone gets
wet, unless it is a deluge, it will get a hard crust on the very top.
Go in and break it up and the cows will go right back and eat it.
No so with mineral that contains grain. It will set up more like
concrete and the cattle won't touch it.
Remember, tags are one thing and can easily be duplicated.
Ingredients are a different story. Vigortone has a slogan, "They
copied what we put on the tag; they should have copied what
the put in the bag."
Vigortone is a performance mineral. Cattle really perform on it.
The new "Next Generation" mineral will have a slightly different
tag, John, and will come in a white and blue bag. They added more
zinc (7500 ppm), took out all the iron as iron ties up copper and
added more Vitamin A. They did away with the mineral oil to settle
the dust, as it is a petroleum product and they now use soybean oil.
