What Do Llamas Eat: Complete Feeding Guide

Understanding what do llamas eat is the foundation of responsible llama ownership and husbandry. Llamas are herbivores with a digestive system finely tuned to low-quality forages. In their native Andean highlands they graze on tough highland grasses, but in captivity their diet needs careful management to keep them healthy. This guide covers exactly what they eat, how much they need, and which foods are dangerous for them.

The unique digestive system of llamas

Specialized digestive anatomy

Llamas have a three-compartment digestive system (they are not true ruminants like cattle):

• Compartment 1 (C1): 83% of total volume, functions similarly to a rumen
• Compartment 2 (C2): 6% of total volume, acts as a filtration chamber
• Compartment 3 (C3): 11% of total volume, equivalent to the abomasum

This structure allows them to:

• Ferment low-quality fiber with remarkable efficiency
• Recycle endogenous urea to conserve nitrogen
• Extract maximum nutritional value from poor forages
• Maintain a stable pH in the main fermentation chamber

The digestion process

Initial chewing: Llamas chew food only briefly before swallowing it.

Primary fermentation: The food enters C1, where bacteria and protozoa break down fiber over 20–40 hours.

Rumination: The partially fermented material is regurgitated for additional chewing, increasing the surface area available for digestion.

Final digestion: The processed material moves to C3, where nutrients are absorbed with the help of gastric juices.

Natural diet in the wild

Main native forages

Seasonal foraging strategies

Wet season (December–March): Access to tender, nutritious pastures. Daily intake of 8–12 kg of green matter.

Dry season (May–October): Reliance on dried forages and shrubs. Intake drops to 4–6 kg of dry matter per day.

Transition periods: Opportunistic consumption of seeds, fruit, and new growth as available.

Specific nutritional requirements

Energy needs

Energy requirements vary with physiological status:

Essential minerals

Llamas require a specific mineral balance:

• Calcium: 0.4–0.8% of dry matter (gestation/lactation)
• Phosphorus: 0.3–0.6% of dry matter
• Magnesium: Minimum 0.2% to prevent grass tetany
• Sodium: 0.1–0.2%, especially in warm climates
• Potassium: 0.8–1.2% in high-forage diets
• Sulfur: 0.15–0.25% for microbial protein synthesis

Feeding in captivity and on farms

Recommended forages

Top-quality hays:

• Alfalfa hay: 15–18% protein — ideal for gestation and lactation
• Timothy hay: 8–12% protein — excellent for maintenance
• Tall fescue hay: Similar to natural ichu — well accepted
• Oat hay: Palatable and digestible — good for convalescent animals

Hay quality criteria:

• Color ranging from green to greenish-yellow
• No dust, mold, or foreign matter
• Long fiber preserved (minimum 5 cm)
• Sweet, fresh aroma
• Moisture content below 15%

Grazing and pastures

Recommended pasture species:

Grazing management

Recommended stocking rate: 2–4 llamas per hectare, depending on pasture productivity.

Rotational system:

1. Divide pastures into 4–6 paddocks
2. Graze each paddock for 7–14 days
3. Rest each paddock for 21–42 days depending on the season
4. Entry height: 15–20 cm
5. Exit height: 5–8 cm (no lower)

Strategic supplementation

Commercial concentrates

When to supplement:

Feeding programs by life stage

Feeding crias (0–6 months)

0–3 months:

• Exclusive maternal nursing for the first 2–3 weeks
• High-quality alfalfa hay available ad libitum from week 2
• Fresh water always available
• Starter concentrate (18–20% CP) from week 4: 100–200 g/day

• Prevention: Gradual feed transitions, effective fiber >18%
• Treatment: Withdraw concentrates, offer hay, administer bicarbonate

Impaction:

• Cause: Very dry forage, insufficient water, stress
• Symptoms: No defecation, abdominal distension
• Prevention: Constant water access, adequate fiber, exercise
• Treatment: Mild laxatives, rehydration, veterinary management

Nutritional deficiencies

Copper deficiency:

• Symptoms: Fleece discoloration, reproductive problems
• Treatment: Copper sulfate supplementation (100–200 mg/day)

Selenium deficiency:

• Symptoms: Nutritional myopathy, retained placenta
• Treatment: Selenium + vitamin E, monthly injections

Detailed frequently asked questions

How much should a llama eat per day?

An adult llama consumes 1.8–2.5% of its body weight in dry matter daily. For a 150 kg llama, that equals 2.7–3.8 kg of dry matter, or approximately 6–8 kg of hay at 12% moisture. During lactation, intake can increase to as much as 3.5% of body weight.

Can llamas eat fruits and vegetables?

Yes, but in moderation. Fruits such as apples (seed-free), pears, and carrots are safe in small amounts (maximum 500 g/day). Avoid citrus fruits, grapes, and stone fruits. Leafy greens like chard and spinach are fine occasionally.

Do llamas need grains in their diet?

Not necessarily. Llamas can be maintained on quality forages alone. Grains are used as an energy supplement during gestation, lactation, or heavy work. When used, oats and barley are preferable to maize, and the total should never exceed 1 kg/day to avoid acidosis.

What should I do if a llama refuses food?

Loss of appetite can signal illness, stress, or poor-quality feed. Check the freshness of the forage, water availability, signs of disease, and potential stressors. If the problem persists beyond 24 hours, consult a veterinarian who specializes in camelids.

Should feeding change with the seasons?

Yes, especially in grazing systems. In winter it may be necessary to supplement with higher-quality hay and boost energy for thermoregulation. In summer, ensure shade and plentiful water. The amount of concentrate also varies depending on the seasonal availability and quality of pasture.
