I have got two boar cross 9 month old wethers to butcher. These are my first goats and my husband went to pick them up and the seller told him to worm them and wait 30 days to butcher. He could not remember the exact name of the wormer but said it was one of my poultry wormers, either piperazine or Ivomec? I tried searching this site for worming info and was confused. Does anyone have any suggestions on what medications I need to give them and how long to wait before butchering? I live in NE Oklahoma. Thanks for your help! edited: As an answer below pointed out, do I need to worm them? I wanted to butcher them in two to three weeks at the latest. So do I need to worm?
