Lectures 1-5 Flashcards
What are the three components of emotion?
subjective component, behavioural component, neurophysiological component
What is the term to describe the needs of an animal and how they vary between individuals of different species or within the same species but of different age?
telos
What are the four needs of an animal?
nutritional, environmental, health and behavioural needs
What model is used to link the needs of an animal with mental state e.g. positive and negative emotions?
Mellor’s Five Domain Model
What are the four tests which can be used to test an animals needs?
preference test, strength of preference test, aversion test, deprivation test
What 6 types of sampling can be used to create an ethogram to assess an animals needs?
behavioural, point, period, focal, scan, ad lib sampling
What test requires an animal to make a sacrifice to gain access to something when assessing an animals needs?
preference testing
What is the test which tests consumer demand when assessing an animals needs?
operant testing
What is inelastic demand and what is an example?
a demand which is needed at any price e.g. oxygen
What is the test in which the strength of motivation to avoid an aversive situation is measured when assessing an animals needs??
aversive testing
What is the test in which an animal is deprived of a supposed need and the effect of the deprivation on any pathological changes to its physiology or behaviour are noted when assessing an animals needs?
deprivation test
What state is entered when an animal is not able to meet its needs?
stress
What is the definition of ‘coping’?
having control of bodily and mental stability
What is the definition of welfare?
the state of an animal with regard to its ability to cope with its envrionment
What is the term used to describe the process that keeps the organism alive and function ie maintaining homeostasis or maintaining stability through change and promoting adaptation and coping?
allostasis
What are 5 causal factors which affect motivation of an animal?
hormone, oscillators e.g. circadian rhythms, internal factors, external factors, memories
What is a telo-receptor?
receptor which measures at a distance
What is an exterior-ceptor?
receptor associated with skin contact
What is an interio-ceptor
internal receptor
What is a stressor?
a stimulus that exceeds its normal limits in terms of intensity or duration
What does stress stimulate the hypothalamus to produce and which is this effect?
produces CTRF which stimulates the pituitary gland to produce ACTH
What does ACTH do?
Stimulates the adrenal cortex to produce cortisol
What is the term describing the high level stress response which has high biological cost, is damaging to the animal and probably sensed by the animal as unpleasant?
distress
What is caused when an aim generated by causal events cannot be achieved?
frustration
In general terms what is measured when assessing welfare?
whether the physiological, ethological (behavioural) and health needs are being met
What causes pale soft exudative meat?
the release of glycogen from meat in pigs caused by stress
What causes dark firm and dry meat?
pigs using up glycogen stores from muscle because of starvation on a journey
What two hormones are associated with general adaptive syndrome?
adrenaline and cortisol
What occurs to the level of cortisol during chronic stress?
levels decline
What 4 events can cause rise in cortisol levels?
novel situation, copulation, oviposition in fouls, stress
What about reproduction can be measured as a physiological measure of welfare?
number of offspring, levels of LH and FSH
Does stress cause hyperthermia or hypothermia?
hyperthermia
What hormones other than adrenaline and cortisol could be measured as a assessment of stress?
oxytocin, ghrelin, vasopressin, beta endorphins
What is critical anthropomorphism?
looking at an animal from their perspective as opposed to our perspective
What are the 6 classifications of abnormal behaviour?
self-directed, environmentally directed, directed at other animals, failure of function, anomalous reactivity, stereotypic behaviour
What are the two categories of self-directed abnormal behaviour?
self-multiation, self licking/plucking
What are the 4 categories of environmentally directed abnormal behaviour?
interacting with solid objects, eating litter, coprophagia, geophagia (soil eating)
What do animals see other animals as in abnormal behaviour directed at other animals?
objects, sexual objects, mothers, rivals
What functions can fail in the failure of function classification of abnormal behaviour?
sexual function, parental behaviours
What are 2 examples of anomalous reactivity which can occur in abnormal behaviour?
prolonged inactivity, hyper-reactivity and hysteria
What drug can block some stereotypic behaviour?
naxolone
What are the two ways of assessing the effects of husbandry/production systems on welfare?
outcome based measures, resource based measures
What are resource based measures of welfare based around?
the Farm Animal Welfare Committees 5 freedoms
What concept relates to assessing the welfare of an animal at different time points in its life?
Hazard Analysis and Critical Control Points (HACCP)
