Animals in Captivity Flashcards
How can we improve welfare of captive animals?
using ecology, ethology, and clinical animal bhvr
How do we improve welfare in captive animals?
- Providing element of CHOICE
- Get zookeepers etc to support this
- Get emotional health good (anxiety = bad)
What is ABNORMAL bhvr?
- Performing a normal species-specific behaviour in a wrong context.
- Performing a behaviour that is unseen in the wild – normal vs natural
behaviour - Performing a repetitive behaviour that serves no purpose.
- Abnormal repetitive behaviour (ARB) is categorised as repeated goal oriented
(OCD) or repeated motor function (stereotypies).
Describe ARBs (Abnormal Repetitive Behaviour)
- Abno bhvr = coping mechanisms and stopping/preventing bhvr alone can deteriorate animal’s emotional state
- Some species adapt better to captive environments than others
- Complexity of environment, individuality and previous experience contribute to ARBs
How can we measure animal welfare in captive wildlife?
- Physiological parameters
- Bhvr observation
- Welfare Assessment rools (Grid 5AWAG), Qualitative Bhvr Assessment (QBA)
- Bhvr measurement
- Ethogram
What physiological parameters can we assess?
Hormones
Heterophil:Lymphocyte ratio
describe Hormone measurement
Hormones – prolactin, oxytocin, glucocorticoids – Faeces, urine, saliva, hair
*Cortisol, corticosterone levels increase when animal is in a stressful state
*Consider if a realistic measure and convenience
Describe Heterophil:Lymphocyte ratio
*WBC’s take longer to response to stress. Therefore, better to detect chronic stress than
corticosterone.
*Stressors like food/h20 deprivation , light exposure, extreme temperature increases
heterophil and depresses lymphocytes.
How do we do bhvr measurement
- Manual recording on paper or device using coding
- Video or audio recording followed by manual recording
- Automatic based on bhvr, space, or other
Describe an ethogram
- Behaviours are described and coded to record behaviours easily.
- Must be very specific and detailed so its repeatable.
- Eg how would you differentiate a sleeping monkey vs a resting monkey?
What methods of Sampling are there ?
Recording Rules?
What can we do to inc welfare in captive wildlife?
- Optimising environment : -> in complexity, avoid over-complicating - lead to frustration; feeding methods
- Allowing expression of species specific bhvr:
- Provide suitable types of enrichement
- Uses all senses
- Test cognitive skills
How do we improve quality of life?
- Training for welfare and health purposes.
-> *Aim to reduce restraints for routine procedures & Build confidence - Breeding for adaptability
- Managing emotional health -> Avoid suppression ; Desensitisation + Counter conditioning
- Therapeutic management -> Hormones / Pheromones ;
Nutraceutical ;
Psychoactive medication
