snipping to answer a single question

no because beef herds will get mineralised blocks or similar
which
dairy
cattle will never normally be offered.

But beef herds use salt licks at will. Added to feed, the
animal
has no choice but to ingest it.

you haven't the faintest idea what a mineralised block is have
you.

Humour me.

One example is below. Farmers know this product intimately. The blocks
weight fifty pounds and you have to lug this block across frozen fields
and
swollen creeks to get it to the blasted cattle. Got a set of bruises on
my
ribs now from humping one of these things out to the lower pasture
through
the ice storm a few weeks ago. The ice won, I fell on the thing.

Thanks Michael. I'm well aware what a mineralized 'salt lick' block is.

Never "heard" it called that before.
