Worms clinging to horses lungs??? I've never heard this.
This is what I know...
Horse Wormer is considered to be a neurotoxin and as such affects the nervous system of the worm. So it is absorbed through the GI tract of the animal, kills the parasite, and the animal expels the rest. I wouldn't assume that food consumption would change it's efficacy.
Although, I am not a vet.
Life seems mighty precious, when there's less of it to waste.
