<font size=3D3>Mr. Grasser and all,<br><br>
There has been substantial NEGATIVE research on providing
"individual" minerals and vitamins (cafeteria style) to
livestock so that they can balance their own
requirements/needs.<br><br>
It is <b><u>not</u></b> true that they can balance
their own needs OR
requirements by selecting the individual correct mineral or in the
correct amount. It is especially not true when the requirement is
in PPM (parts per million =3D i.e. one blade of grass in an American
football grass field).<br><br>
It is especially difficult for the animals to balance their own
requirements/needs when the mineral tastes like #?$*&%. The
livestock will not consume it. AND on the other side, when the
mineral/vitamin is very palatable (i.e. Vit A), then you can go broke
supplying or feeding it.<br><br>
In the late 1970's and early 1980's there was a company in the U.S. that
claimed by providing minerals, cafeteria style - they could satisfy =
their
own requirements. They are no longer in business to my
knowledge.<br><br>
And the best barometer for mineral status of any livestock is to conduct
Liver Biopsies of a representative sample of the herd or flock while =
they
have been grazing (for several months) on the range/paddock that =
supplies
their forage/nutrition.<br><br>
IIt is not best to only sample a single animal that died or the barren
heifer that you have been feeding "brought in or truck in"
supplied grain or feed The reason being is that feed may already =
be
"fortified" with minerals/vitamins or came from or was grown =
in
an area that was adequate or had high levels of a particular
mineral.<br><br>
Be cautious and ask questions of scientists, veterinarians, professors,
cooperative extension specialists if you have been told something that =
is
hard to believe.<br><br>

I recommend the Pat Coleby ideas to many clients and friends who
manage<br>
animals with the proviso that they have to understand what the
likely<br>
mineral deficiencies are in the environment in which the animals grow.
<br><br>
If their diet is limited in any of the trace and basic elements (you
can<br>
check by soil or foliar testing of pasture), they will seek these in<br>
whatever form can be readily obtained. I suggest the use of the
ingredients<br>
she suggests (copper sulphate, sulphur, salt, dolomite, seaweed
meal)but<br>
that they be made available as separate items so that the stock can
select<br>
what they want when they want it. There have been times I know of
where<br>
liver copper toxicity has been a problem because the animal has taken
the<br>
mix and ingested more copper than it required. It was most likely
needing<br>
more seaweed meal than the copper but found itself being poisoned by
the<br>
imbalance.<br><br>
In short, check the background mineral status in your area and of
the<br>
brought in feed and make the individual ingredients available
free-choice.<br><br>

Subject: [Graze-l] Cu, S, and Ca/Mg for beef and sheep<br><br>
Anyone have any experience with using high Cu and/or S mineral mixes =
such
as<br><br>
suggested by Pat Coleby, for beef or sheep?<br><br>
She recommends using dolomite as part of the mix, or sometimes offering
<br>
plain dolomite. Anyone have any experience with this? Is
there a special <br>
form of dolomite, or should I just buy something at a garden shop?
Will <br>
your animals eat it?<br><br>
