grey hair and minerals

[Guest guest]

Here's a little bit of interesting information I came across on

minerals and sheeps hair color. It's from the Albrecht paper " Soil

Treatment AND WOOL OUTPUT " .

" Color and trace elements

The color of the black wool of black sheep is also related to the

presence of these trace elements, especially with the copper.

Australian black sheep, grazing on pastures on these coastal soils,

lose the black color to become gray. When given copper and cobalt in

the feed, or the drench, the black color is restored.

In many parts of the United States it is commonly said " Black

sheep never stay black. They always turn gray. " It might well be

questioned whether this is not merely saying that our soils are

copper deficient, and possibly even cobalt deficient. We have only

recently begun to think of these so-called " trace " elements and

their importance in the body's production--not of fats, but of its

proteins, even of the different amino acids constituting the

proteins. "
