[Jacob-list] Re:minerals, symptoms

[Mary McCracken]

Tired and achy.  What's the cure for THAT I'm wondering!!  

Wrestled my big long legged suffolk ram into the horse trailer after he jumped the electric fence three times to get to the apple trees.  I'd been dumping buckets of apples in with them but apparently he wanted to select his own.  So I'll be reporting on how apple fattened mutton is!!  The targhee ram says 'I'll be good'.  Not sure if he is referring to the fence and apple trees or to the suffolk ewes.  mary

    I have the book, Feeds and Nutrition, but it is an old edition (third).  In it it states that copper deficiencies have been reported in Florida and the coastal plains regions of the the Southeast. It mentions something about adding .5% copper sulfate to the salt mix.  I believe that .5% is something like 5 parts per thousand.  I may be wrong- I'm tired and achy today. 
    It does go on to mention a total intake, rather than a percentage, as toxic.  It might be interesting to figure just what your sheep are eating and calculate on that.
    
    Feel free to argue with me on the list - I'm here to learn.
