I've used safeguard equine paste in the past, but not anymore. I use safeguard liquid goat wormer and valbazen. Liquid wormers are much easier to administer and have a quicker effect. I've used and will continue to use zimectrin gold equine paste IF my birds get tapeworms.
What equine paste are you using? Most ivermectin pastes without praziquantel contain 1.87% ivermectin only. I dont recommend ivermectin only pastes at all.
