Some llamas enjoy treats and they will eat, but their main source of energy comes from forage.
Llamas are herbivores, which means that the vast majority of their diet is vegetation like grass and various plants. Their bodies are not designed to process meat effectively.
Llamas are not extremely picky eaters and will eat shrubbery and other less ideal vegetation to survive in dry climates. They will eat hay, grain, some fruit, and fresh veggies like carrots and broccoli.
Llamas require forage to provide the fiber and nutrients they need. Appropriate forage for llamas includes timothy, fescue, and orchard grass as well as legumes such as alfalfa and clover.
Llamas enjoy treats but as with all animals, any treat should be fed only in moderation. A number of llamas like to eat treat like carrots, apples, sweet potatoes, raisin, broccoli, and bananas.
