Jim Thode	I have a comment about: selenium-deficiency-in-your-horse article This article states explains that horses usually need just 0.1 mg/kg selenium daily when inactive, then 0.3 mg/kg when in an exercise program or working as a broodmare. For a 1000 lb (454 kg) horse this would be 45.4 mg for inactive and 163 mg active. The FDA has set a recommended daily limit for selenium intake in horses at 0.3 ppm (parts per million) or 3 mg per day. Doses of 5 mg or more of selenium per day can cause mild to severe toxicity in a horse. If the your article was followed a horse could die from an overdose!	6/16/2009
Marcus M	I thought the same things, but wasn't really sure if my theory was correct. Brilliant minds think alike. :)	7/14/2007
