Dung Pile Communal Dung Piles Llamas and alpacas urinate and defecate in communal dung piles. This concentrates all the urine and feces in a smaller area than if they just went all over the field or barn like other livestock. The areas where they do not urinate and defecate remain clean and dry for grazing, laying, breeding or rolling. Dung piles make it easy for llamas and alpacas to graze around dung piles in pastures. Avoiding oral contact with feces decreases the parasite load of the herd.
Parasites can spread only if the new eggs and larvae in the feces are ingested again by an animal.
This does not mean that llamas cannot get parasites. It just means they are at a decreased risk as compared to animals which urinate and defecate all over the barn and pasture. Llamas and alpacas can still ingest parasite eggs and larvae at the outskirts of potty piles. A dung pile outside the barn in a llama paddock. It tends to spread out instead of piling up.
