Re: [Alpacasite] Stubborn internal parasites

We lost two males here a few years ago. Necropsy said they were loaded
with parasites despite the fact that we'd wormed everyone regularly and
had wormed these two more often when they didn't seem quite right. Our
vet felt that both these boys may have had an underlying problem like a
depressed immune system. He felt that was the only way that the rest of
the herd could be fine while these two were dead. Their depressed immune
system left them wide open to parasite infestations.
