Welfare Flashcards
What are the five freedoms?
Hunger/thirst, thermal/physical discomfort, injury/disease, normal behaviour, fear/stress
Instead of the five freedoms, what does the AWA 2006 introduce?
Five Needs
What are the Five Needs?
Environment, diet, behaviour, with/apart from other animals, protection from pain/suffering/injury/disease
What did Welfare Quality (2009) define instead of the Five Freedoms/Needs?
Four principles for good welfare
What are the four principles for good welfare?
Feeding, housing, health, behaviour
What is the difference between a feeling and an emotion?
Feeling increases chance of survival, whereas emotion includes subjective and expressive (behavioural and neurophysiological) components
What is a common problem with veal calves?
Iron deficiency anaemia (weak and poor breathing)
What kind of activity do animals show is prevented from meeting a behavioural need?
Rebound activity
What are three kinds of tests that can be done to determine an animals behavioural needs?
Preference, aversion, deprivation
What is an ethogram?
Detailed description of he behavioural features of a particular species
When can there be problems during preference testing?
If the stimulus is not related to the telos of an animal - may not respond because they don’t have the receptor
Why is CO2 stunning of pigs aversive?
Nasal mucosa irritation
What is alostasis?
keeping the organism alive and functioning (homeostasis, adaptation, coping)
What is agency?
Engaging with the environment to gather knowledge and enhance skills
What is a teloceptor?
An event at a distance
What is an exterioceptor?
Skin contact
What is an interioceptor?
Visceral/physiological state
What causes meat to become PSE?
Too rapid glycogen release
What happens if all glycogen is released or used up?
Meat becomes dark and dry
What are four types of abnormal behaviour directed towards another animal?
Animal as: Object to acquire, mother, sexual object, rival
What are the two kinds of anomalous reactivity?
Inactivity or hysteria
Why is sympathetic GAS hard to measure?
Short half life
What parameters can be used to measure the sympathetic GAS?
Heart rate, pupil dilation, skin temperature
How soon is cortisol released after stress?
2-3 minutes
Which samples can cortisol be measured in?
Blood, urine, saliva, faeces
By what mechanisms does cortisol increase nutrients in the blood?
Gluconeogenesis, protein breakdown, lipolysis
Why does cortisol cause increased blood volume?
Retains Na+
Which interleukins mediate chronic corticosteroid immunosuppression?
IL-1,2,b
Which three immune cells are inhibited during chronic corticosteroid release?
Antibody, T cell, macrophages
Which stressors do not cause cortisol to rise/remain high?
Heat, chronic confinement, chronic pain
Which hormone level falls with stress?
Prolactin
Which three challenges can affect LH and FSH levels?
Transport, high temperatures, low feed intake
Which hormone classes mediate stress induced hyperthermia?
Interleukins, prostaglandins, vasopressin
Which kind of animal is prone to stress hyperthermia?
Captured wildlife
Which hormone acts as an indicator of energy reserves?
Leptin
Physiological responses to emotional stress?
Adrenergic, adrenal, core body temperature, ghrelin, reduced LH GRH and prolactin
Physiological responses to pain?
Adrenergic, adrenal, trauma enzymes and inflammatory markers
Physiological responses to osmotic stress?
Adrenergic, adrenal, haemoconcentration parameters
Physiological responses to energy depletion?
Insulin, glucagon, leptin, glucose, urea
Physiological responses to thermal stress?
GAS, prolactin, temperature (core and skin), panting, sweating, reproductive hormones
What are two examples of failure to function behaviour?
Sexual inadequacy, parental behaviour (neonatal rejection)
Which kind of neural system is involved in stereotypic behaviour?
Dopaminergic
What stimulates and blocks dopaminergic neural systems?
Amphetamines stimulate, naloxone blocks
What kind of oral stereotypies are common in low input environments?
Those associated with high input receptors
Which Act regulates the profession, controls memberships, has a code of conduct, client and welfare duties?
Veterinary Surgeons Act 1966
What are the two types of witness?
Witness in fact, expert witness
What is the difference between the two types of witness?
