Camelidae and Cervidae Geriatric Diseases – NAVLE Study Guide

Overview and Clinical Importance

Geriatric diseases in camelids and cervids represent a growing area of veterinary concern as these species increasingly survive to advanced ages in managed populations. Camelids (llamas and alpacas) can live 15-25 years, while cervids (deer, elk, moose) may live 15-20 years in captivity. As these animals age, they become susceptible to a variety of multisystemic conditions that require specialized management approaches.

Understanding age-related changes in these species is critical for the NAVLE, as questions frequently address differential diagnosis, management strategies, and species-specific pathophysiology. This guide covers the most clinically significant geriatric conditions affecting both camelids and cervids.

Section 1: Camelidae Geriatric Diseases

Camelids (llamas and alpacas) are increasingly popular in North America as fiber animals, companion animals, and livestock guardians. Unlike other livestock operations where older animals are typically culled, geriatric camelids are often retained in herds, making age-related diseases a common clinical presentation. The alpaca lifespan is 15-20 years, while llamas tend to live slightly longer with proper care.
