Hi Erna -- and welcome.  It's so nice to have another international list 
member!!  I can help you with your questions pertaining to horses and CS.  I am 
co-moderator on an internet list whose foundation is using Colloidal Silver for 
horses.  I think that the information you got of using several drops of CS for 
your horse must have come from a source of allegedly high-ppm CS.  Since you 
will soon be making your own CS, you will probably be producing something in 
the range of 5 ppm to 20 ppm.  This is a fine product for horse care.  My 
recommendation is that you mix ONE CUP of this CS in with your horse's feed 
ration, 
morning and night.  It helps if you feed something that will absorb the CS -- 
such as rolled oats, or a pelleted feed.  Adding CS to the water is my least 
favorite way of dispensing it.  By giving your horse this amount of CS, you 
will find that he (the pony too - I'd give him 1/2 cup twice a day) will be 
extremely healthy and will avoid many of the virus problems that horses can 
pick 
up.  We also use it topically for skin problems.  If you'd like to join the 
equine list and learn more about CS use for your horses (and your dog) let me 
know by private email and I'll send you the addy.   Mary Ann in Kentucky, USA
