Read my post "More MIX30 Conversation" in the Grasses, Pasture, and Hay section. It is an excellent product for us. It does separate over time, but doesn't take much to get blended back. You say you are getting it delivered...do you mean in bulk, or do they provide it as a service and fill your tanks for you, (similar to Loomix, out her in Colo.) If it is a service you won't have to worry about separation.
It also makes the cattle's coats shiny, and it must pass through the milk because our calves are as healthy and shiny as ever. Probably the energy (fat) in MIX30.
Let me know how it works for you. If you have trouble with their consumption rate, move the lick tanks to a more distant location from the water source.
