I just buy the cattle boluses and then dose it at 1cc per 60 lbs. I cut off the tip of a 3cc syringe and then pour the copper into it. Then I put a dab of Probios on the end to hold the rods in. Put in back of mouth and push plunger.
I use Coppersure.. It's made for calfs, but I open the capsule up and put it into smaller gel caps. I dose it at 1cc to every 50#.. I like to use the gram method but my gram scale only weighs whole increments so it wouldn't be very accurate.. So until I get a new one I will does 1cc to every 50#
