Salt is just that........salt. And cattle need salt but how could salt help
the immune system? What about copper, zinc, Vit. E, manganese,
yeast culture?
I knew a lady who tried this on an old horse, having been told it was
a cure-all. The horse died...not from being fed the sea salt, but
because he was old and needed mineral supplement badly. And calcium.
And phosphorus.
The sea salt thing has been around for years. And the calcium and phos
in the hay isn't all that available to a cow. That's why mineral has been
studied and recommended for the last 15-20 years and found
to be necessary in a balanced diet. It wasn't all that long ago that
hay and salt was all that was fed and look at the problems that
ensued as a result.
As expensive as cattle are now, I sure wouldn't be trying it.
Katrina, ask the people that are talking about this for some
research on the subject.
Hope this helps!
