The weight of an alpaca:

What does an alpaca weigh?

The weight of an alpaca can vary depending on factors such as gender, age, and health. Generally, an adult alpaca weighs between 55 and 90 kilograms.

Specific weights:

  • Males: Adult males typically weigh between 70 and 90 kg.

  • Females: Adult females are usually a bit lighter, weighing between 55 and 75 kg.

  • Young alpacas (crias): A newborn cria typically weighs between 6 and 9 kg, depending on the breed and conditions.

The weight of an alpaca can also be affected by the breed. Larger breeds, such as the Suri alpaca, may be heavier than smaller breeds, such as the Huacaya alpaca.

How do you determine if your alpaca has a healthy weight?

It is important to regularly check your alpaca’s weight and body condition to ensure its health. Here are some methods to assess if your alpaca is in good condition:

  1. Body Condition Score (BCS)
    The Body Condition Score (BCS) is a numerical rating that helps you assess the body condition of your alpaca. The score ranges from 1 to 5, with a score of 3 considered healthy:

    • Score 1 (too thin): Ribs, spine, and hips are clearly visible.

    • Score 2 (too thin): Ribs are palpable but not visible.

    • Score 3 (healthy): Ribs and spine are lightly palpable but not visible. This is the ideal weight for an alpaca.

    • Score 4 (full): Ribs are hard to feel, there is some fat accumulation.

    • Score 5 (too fat): Ribs are not palpable, clear fat accumulation, especially along the spine and hips.

  2. Feeling the Ribs
    A healthy alpaca should have ribs that you can feel, but they should not be visible. If you cannot feel the ribs, it may indicate overweight, while visible ribs may indicate underweight.

  3. Body Shape
    A healthy alpaca has a balanced body shape without excessive fat accumulation. The belly should not sag, and the spine should be palpable but not painful.

  4. Behavior and Energy
    Healthy alpacas are active and have a normal appetite. If your alpaca seems lethargic, lacks energy, or withdraws, it may be a sign of a weight issue, such as underweight.

  5. Muscle Mass and General Appearance
    A healthy alpaca has well-developed muscles, especially in the shoulders, thighs, and neck. Overweight alpacas may have fat deposits along the neck and belly, while underweight alpacas may appear emaciated.

  6. Coat Health
    A healthy alpaca has a shiny, full coat. If the alpaca is underweight, the coat may look dull or fall out, while overweight alpacas may have difficulty maintaining their coat due to fat accumulation.

  7. Weekly Weight Check
    Regularly weighing your alpaca can help you determine if it has a healthy weight. If you don’t have a scale suited for larger animals, you can try estimating the weight at the vet or using a weighbridge.
