Constipation in llamas or alpacas may be suspected if you notice your animal
spending an abnormal length of time at the "poop pile"
without any, or little, results. They may repeatedly return to the
"poop pile" and spend quite a bit of time in the position and possibly
straining, but not very much comes out.
You also may observe other signs of discomfort such as rolling, acting
lethargic, or a change in eating habits.
Two hints from llama breeders:
1. "If you think he may be constipated or uncomfortable, give
him a couple of turkey basters
full of Mineral Oil by mouth. Follow this by offering them a pan of tepid water."
2. "You might try some probiotics and give him a 'Fleet' Enema. That should give some relief.
