Exam Prep Flashcards
Animal rights in the 17th century
Non existent
Animals weren’t believed to have a conscience
Welfare in 1826
First animal welfare law created in uk
Naturalistic argument
Enclosures should be as natural as possible to encourage natural behaviours
Fit and healthy argument
If an animal is healthy the welfare is good
Holistic argument
Animals should be fit and happy
Five freedoms (FAWC)
Freedom from: Thirst,hunger and malnourishment Discomfort Pain and injury Fear and distress Behave naturally
Three principles of ethics
Autonomy - rights to body
Justice - equal to all
Beneficence - benefits the animal
Animal welfare act (2006)
Authorities can punish cruelty and enter properties
Displacement behaviour
Normal behaviours at abnormal times,frequencies or lengths
Why do displacement behaviours occur?
Often after stressful encounters eg conflict
What is a stereotypy
Irregular behaviours often used to comfort a animal eg swaying which often becomes impulsive and hard to reverse
Mantra effect
Repetition of a behaviour brings comfort
Younger animals…
Often need extra stimulation to encourage exploration and reduce the chances of stereotypical behaviours in later life
Treating stereotypies
Improving welfare can reduce these behaviours but often they cannot be reversed without causing stress to the animals
Welfare
An animals ability to cope with its environment with both mental and physical components
Preference testing
Tests motivations and the strength of motivation towards different environmental factors
Consumer demand theory
Different animals have different preferences dependent on their age,sex,experiences etc
Cognitive bias and emotional state
Depressed individuals are often more pessimistic and less explorative
5 domains
Nutrition and hydration
Environment
Health
Behaviour and mental state
Explain the stress response
Sensory input
Brain evaluates
Positive or negative emotions generated
Body responds physically or mentally
What’s HPA?
Hypothalamic pituitary axis (hormone slow response)
What is the SNS
Sympathetic nervous system involving nervous system (fast response)
What is GAS response?
Alarm
Resistance
Exhaustion
Problems with chronic stress
Poor immune system
Lack of growth
Physical measures of stress
Blood pressure MRI Hormone samples Glucortinoids Resp rate
Cruelty to animals act (1976)
Prevents cruelty to animals. Infliction of pain when justified is ok but cruelty isn’t
Types of licenses
Personal
Project
Establishment
Regulated procedures
Mild moderate or severe
Licenses needed if any pain is inflicted
3rs
Replacement
Reduction
Refinement
What is white adipose tissue?
Stores energy
What is brown adipose tissue?
Thermoregulation tissue to help young animals and hibernating animals stay warm
Adipokenine
Reduces appetite. High levels increases appetite
Adipokenectin
Enhances insulin sensitivity
Lower in overweight animals
Neoteny
Delayed development
Paedomorphism
Juvenile features in adults
1930s
First stereotypy observed
1960s
Documentaries changed welfare attitude
1961
First American welfare laws
WAZA
World association for zoos and aquariums
Naturalistic
Mimics wild enclosures
Behavioural engineering
Doesn’t mimic wild but stimulates natural behaviours
Types of enrichment
Social Occupational Physical Sensory Nutritional
Allostatis
Balance through physical and behavioural changes
Allostatic load
Costs incurred
Ideal sheep body score
2-3 - measured by feeling hips and lower spine- should be round and not sharp
Typical sheep behaviour
Social
Not isolated
Alert
Recommended sheep water distance
Less than 1.6km
What is rewilding?
Undomesticating animals/ releasing into wild
Oostvardenplassen
Cattle and ponies reintroduced with wild red deer all now starving and culling is being used —— unethical
Reintroduction
Releasing captive bred animals
Reintroduction objectives
Survive
Breed
Settle
What causes mortality in reintroduction
Stress
Predators
Habituation to captivity
Problems with reintroduction
Money
Time
Lack of behavioural skills
Captivity habituation
How to help reintroduce
Enrichment stimulating natural behaviours
How to help carnivores reintroduce
Natural foods or live foods
How to help arboreal reintroduce
Distribute food specially
Captive animals often don’t….
Experience stress which may be detrimental when introducing
Anti predator training
Mimicking predators to captive animals to prepare for reintroduction
Why does nutrition change
To accommodate to different life stages
First ingestion or milk
Colostrum helps build the immune system
Diet
Regime of food
Food
Substinance
Nutrient
Substance used for energy
Lab animals are fed…
Cereal based diet
Poor diet leads to
Deficiency diseases
Obesity
Cardiovascular diseases
Faulty leptin
Leads to over eating due to no appetite suppression
Protein requirements
Higher for pregnant,lactating or growing animals
Postpartum rats
Can conceive hours after giving birth
Proteins help
Build tissues
Grow
Poor protein leads to
Small litter sizes Poor Development Low birth rates Reduced growth Poor lactation
Carbohydrates
Energy rich
Excess converted to fat
Purified synthetic diets
Cleansed/no chemicals (better for experiments as no variation)
Standard lab diet
Mostly natural ingredients,variation possible
Water
Lubricates food
Transports waste materials
Regulates body temp
Biofilm
Contaminates water (bacteria colony)
Treated with reverse osmosis and filtering
Should check planktonic count regularly
Cruelty to animals act – 1876
means animals in labs can only be in justified experiments. Can inflict justified pain but not be cruel.
Why are primates in captivity?
Zoos,captive research,lab facilities,conservation
Ethical concerns of keeping primates in captivity
Development and mental stimulation due to high intelligence.
How should arboreal species be catered to within captivity
Larger vertical spaces
What does spacial crowding lead to in primates?
Social aggression
What is acute stress?
Temporary short term stress
What is chronic stress?
Long term, reoccurring stress
Where is leptin secreted from?
Adipose tissue
