Transcript of Restraint of Zoo Animals

Restraint of Zoo Animals
Problems During Restraint
TASK

IDENTIFY PROBLEMS THAT MAY OCCUR DURING RESTRAINT

Think about the following animals
• Tiger
• Meerkat
• Boa Constrictor
• Penguin
• Ring-tailed lemur
• Zebra


Stress
May be minor

May cause psychological changes that are life threatening

Stress should be minimised once the animal has been captured – HOW?
Blindfolding may reduce stress
Noise should be minimal
Any procedures should be carried out quickly

Restraint of recently transported animals should be avoided – WHY?

Amount of stress varies depending on:

Species
Age
Life history (e.g. hand-reared vs parent reared)
Length of time handled
Expertise of the handler
Interaction with other
stimuli (e.g. blindfolding reduces stimulus therefore stress is reduced)

Monitoring During Restraint
Temperature should be monitored
Eyes – monitored and shielded from direct sunlight
Blink reflex can be decreased by anaesthetic resulting in dry corneas
Respiration is a critical parameter and easily monitored
Examining mucous membranes is a simple way to evaluate respiratory and cardiac systems

Animals should be positioned to ensure respiration is not compromised

e.g. Lateral recumbency (head elevated above rumen with nose pointed down) in ruminants to minimise chance of regurgitation

Chemical Restraint
Task
How do you think zoos administer this form of restraint?

Chemical Restraint
Anasthetic - is a drug that causes anesthesia, which is a reversible loss of sensation. These drugs are generally administered to facilitate surgery.

Sedative - or tranquilliser is a substance that induces sedation by reducing irritability or excitement.
ORALLY
HAND HELD SYRINGE
POLE SYRINGE

REMOTE INJECTION (DARTING)

ADVANTAGES OF CHEMICAL RESTRAINT
Reduces the risk of:

Injury to the animal and handler
Exhaustion
Capture myopathy
Heat stress due to physical exertion
Psychological stress
RISKS
Health status may not be known prior
Injury during induction or recovery
Physical injury from dart when using remote injection
Danger from conspecifics due to change in behaviour
Inappropriate drug choice
Excessive/insufficient dose
Hyper/hypothermia
Kidney problems
Human safety related to drugs
Emergency procedures may be compromised in large species
Task
Looking at the options for physical restraint - For what animal and how would you use each one?
• Tiger
• Meerkat
• Boa Constrictor
• Penguin
• Ring-tailed lemur
• Zebra
Use of Firearms
Needed wherever there are hazardous animals whose escape or uncontrolled movement would represent a high risk
All must be licensed
Consult with police to ensure procedures are up to date
Must be readily available but kept in a secure place
Only authorised personnel have control of them

Firearms/dart guns must be:

Properly maintained
Cleaned regularly
Tested regularly
Firearm testing/examination should be recorded

Records
What should be recorded and why?
Dosage of anaesthetic or sedating agents
Weight of the animal and monitor for correct dosage
Restraint procedures
Any problems encountered for next time
Animal’s behaviour during restraint



Species/individual behaviour that might affect the procedure

Photos/videos may be used to evaluate procedure or used for training inexperienced staff

Procedures and techniques can be shared between zoos as some may have more experience with particular species


CAN YOU THINK OF AN ALTERNATIVE THAT MAY REDUCE THE NEED FOR PHYSICAL AND CHEMICAL RESTRAINT?
