Thanks Justin; and burnt,
Cleland, there has been LOTS of conversations here
about mineral. I think if you did a search you could find what people
use. I would suggest you don't buy mineral on price alone, because
it usually isn't a good product.
The reason the mineral you are using turns hard is because it is
inferior and contains grain...which does cheapen the price, but
you lose a lot because of it setting up like concrete. When you
buy mineral, check the INGREDIENTS, not just the analysis.
It's like making a cake, if you use inferior ingredients you don't have
a very good cake to eat. Make sure what you buy has 2-1 cal to
phos, at least; Yeast culture and Vitamin E. It's best to buy
from a mineral company and not a feed company.
You don't necessarily have to have a custom mix. In our area,
everyone uses basically the same formula, based on grass samples
taken in the area. I only know of one exception; and those people
have a lot of moly that ties up copper and zinc, so they needed
a custom mix.
I will caution you to be careful of coated mineral that stands up to wind
and rain. With that coating it isn't as available to the cow; meaning she
can't utilize it as well because of the coating. Particle size is very important;
that's what keeps Vigortone mineral from bonding together
and helps it to stand up to the elements without a coating.
I hope this helps.
Vigortone mineral is having their fall sale right now; in our area it
lasts until Nov. 19th. Good luck!
