Camelids Practical Notes (Alpacas & Llamas)

South American Camelids: Alpacas and llamas are the most common species.
- Alpacas:
  - Primarily kept for fiber production.
  - Often kept as pets or “paddock” animals, with less emphasis on industrial meat production.
- Llamas:
  - More commonly used as pack animals due to their larger size.
  - Serve as working animals.
Comparison to Sheep:
- Alpacas:
  - Smaller than sheep.
  - May be more difficult to handle due to temperament and stress response.
- Llamas:
  - Larger than alpacas.
  - Generally easier to handle for certain procedures, though still present challenges.

Social Needs: Camelids do poorly when alone; they prefer the company of a herd.
Stress Effects:
- Isolation or rough handling can lead to high levels of stress.
- Consequences of stress include:
  - Increased risk of injury (to both themselves and handlers).
  - Poor handling compliance (evident through behaviors such as spitting or struggling).
  - Potential negative health effects, impacting overall welfare and physiology.
Key Handling Principle:
- Control of the head is essential:
  - Leads to a calmer and safer animal.
  - If the head is loose, there is a greater likelihood of spitting or resisting restraint.

Halter/Head Control:
- Implementing halter or head/neck restraint reduces the likelihood of escape attempts.
- A handler who controls the head significantly reduces:
  - Sudden, unpredictable movements.
  - Risk of spitting.
  - Escalation in need for restraint.
Spitting:
- Often misunderstood as true saliva; it is typically regurgitated stomach contents.
- Can spray over the face and upper body, hence positioning should avoid facing the animal.
Physical Restraint/Group Handling:
- Camelids are frequently handled in groups, facilitated through pens/races akin to sheep management.
- Employ calm and steady movements; avoid loud noises and fast chasing.

Camelids are often described as a “sheep–horse middle ground” in practical comparisons.
Blood Considerations:
- Camelids may face unique challenges related to RBC antigens and transfusion reactions.
- New-world camelids exhibit greater antigenic complexity compared to some species, leading to careful considerations regarding transfusion history and monitoring.

Many camelids are maintained outdoors year-round, requiring access to:
- Shelter: Essential for protection against wind and rain.
- Water: Constant availability is crucial.
- Appropriate Forage: Essential for diet and wellbeing.
Wool/Fiber Coat:
- Provides some level of tolerance to cold weather, but shelter is still necessary.

Camelids illustrate high efficiency in fiber digestion, having adapted to thrive in harsh environments.
They can sustain themselves on relatively “low-quality” forage; however:
- Supplementation may be required depending on factors such as pasture quality, season, and physiological conditions (e.g., growth, pregnancy, lactation).

The Body Condition Scoring method closely resembles that used for sheep, involving palpation of the transverse processes and lumbar spine.
General Target: Moderate condition is desired (not excessively sharp or overly fat).
Red Flags:
- Prominent spinal structures/transverse processes indicate underconditioning.
- Over-conditioned animals may face health, reproductive, and handling issues.

Parasites:
- A major cause of mortality among young camelids includes parasitism.
  - For thin animals, it is vital to consider:
    - Fecal testing.
    - Development of a parasite control plan.
    - Review of nutritional status.
Teeth Issues:
- Camelids may possess fighting and canine teeth, particularly in males.
  - These teeth can cause injuries and might require management, such as trimming within specific systems.
Feet/Toenails:
- Camelids have two-toed feet with nails that can overgrow; regular trimming may be necessary.
Skin/Fiber Coat:
- Shearing and management vary based on climate and breed;
  - Proper fiber management is essential for comfort (to prevent heat stress) and overall welfare.

Camelids possess thick skin, making the selection of appropriate injection sites critical.
Common injection sites include:
- Neck/shoulder region: Suitable for subcutaneous use depending on the product.
- Axillary region: Often used for subcutaneous injections just beneath or behind the elbow.
Injection protocols should avoid areas where restraint might be weak or where the animal can react strongly.
- Always adhere to product label guidance for subcutaneous versus intramuscular applications; specific laboratories might have “preferred teaching sites.”

Key Neonatal Points:
- Camelid newborns are referred to as crias.
- They depend on colostrum for passive immunity.
Failure of Passive Transfer (FPT):
- Testing can estimate passive transfer using IgG and total protein concepts.
- Warning signs indicative of compromised crias include:
  - Dullness or weakness.
  - Poor suckle reflex.
  - Pale or abnormal mucous membranes.
  - Increased risk of infections.
Colostrum/Plasma:
- In cases of inadequate passive transfer, plasma transfusion might be necessary under veterinary guidance.
- Monitor closely for potential transfusion reactions, as they can pose significant risks.

Breeding Seasonality:
- Varies widely; management and nutrition have direct influences on fertility.
Smaller genetic pools in certain locations may heighten risks of hereditary issues.

Facilities that handle camelids effectively are characterized by the following traits:
- Calm Environment: Reducing stress is pivotal.
- Avoid Sharp Visual Dead-ends: Enhances ease of movement.
- Flow Similar to Sheep Handling: Nonetheless, facilities should place greater emphasis on minimizing stress.
