Parasites are one of the most important considerations in the overall health of the alpaca. Alpacas that are thin or in poor condition may represent animals with a heavy parasite load. If animals are sick, they will likely be tested positive for parasites.
The higher the density of animals that are kept together, the higher the risk for parasites. Keeping pastures a little higher than lower will lessen the chances for parasites ingested. And, pasture rotation is a must as well as daily dung removal.
Fecals should be done regularly and more often on specific alpacas exhibiting diarrhea symptoms.
