I'm used to just Bagged feeds I guess.
I'm sure there are more knowledgeable people than I.
Would it work well for weaning calves?
Grower?
Would it work good for lactating cows nursing a few calves?
It looks like it would work well for any of the purposes you listed. Price isn't too bad either, considering current feed costs in general. Animals should be able to eat a lot of it without too much risk of acidosis.
