Round worms can be transmitted to just about everything. The worst part about them is they only need two (?) Weeks to fully infest the host. They have a quick lifecycle and a female can lay up to 1000 eggs a day. That's why they can be lethal, especially in puppies. A worm ofthat size has lived out it's lifecycle and is moving externally to lay eggs to find another host.
A few years ago we harvested some (feral) hogs that were so infested with worms their intestines were moving. Moving with millions of worms. Those hogs were not eaten. They were fed to the coyote and buzzards on the ranch. I've never seen anything like it.
To imagine that inside one (or all) of my pigs turns my stomach in knots.
All I had in the medicine cabinet for pig worker is Wazine. You have to feed it through their water system and it's a pain to use. I'm getting them some injectable from the vet tomorrow when I drop everything off.
No more pigs loose in the yard playing clean up. Normally they are given the "leftovers" from when we clean pens. They live digging for bugs through the old hay and make nests out of it. We give them lots to test up, too, they like that. Recently we started letting them out to root up around the pens due to the recent rains. Pens were mucky! They've since dried up and the pigs havent been back in them, but, they are turned out on the "pasture" sometimes so better safe than sorry.
I have a cabinet full of wormers. I don't want to start throwing worker at the animals and get a resistance so I will wait to see what Dr. D. says.
