I'm planning on giving my piggie her first dose of ivermectin. Ever since I got her she has been itching and biting more than I thought was usual. So after reading up on how easy it is to give them ivermectin, I decided to order it and give it a shot. Now that everything is here and I've measured her, I need help figuring out how much to give her. I have Equimectrin that is 1.87% ivermectin horse paste. I read on GL to mix one dose for 250 lbs with 22.00 cc of water (I'm going to use water instead of the other substitutes because its what I have available). She weighs 430 grams. I went to the dosing calculator to see how much I should give a pig her weight, but I'm confused on which oral treatment in the calculator is the one I have. So if someone could help me out I would greatly appreciate it!
