CP - you're being naughty and seditious again 

May I ask if giving a bolus/syringe of chelated copper is effective in horses then? Locally they give it to cattle and sheep though my land isn't short (5.5ppm) some of the bought in hay appears to be.Copper is stored in the liver and variations from one day to the next will be evened out by using that store. As you say, you need someone to tell you the safe maximum dose. I am feeding the equivalent of a 1/2 dose of Copper Trition, so I can't help you there I'm afraid.
