intro to animal welfare Flashcards
welfare refers to
the state of an individual as it attempts to cope with its environment
thermoneutral zone (TNZ)
where adaptive responses can maintain homeostasis
two ends are LCT (temperature where metabolic rates rises above basal levels to generate heat ie shivering) and UCT (temp where evaporative cooling is triggered ie sweating)
prescriptive zone
body temp changes due to exercise and metabolic rate, a little uncomfortable but adaptation mechanisms allow body to be fine
tolerance zone
outside of prescriptive zone, stress, adaptation alone is not enough to maintain body temp, may compromise physiologic functions but will survive
survival zone
outside of tolerance zone, risk of death, severe stress
biological function
behaviour, physiology, health and productivity
-welfare is good when animals coping well
-welfare poor when these bodily functions not within normal limits
affective state
ability to experience positive and negative feelings or emotions
-good AW when animal adapts without suffering in interactions w other animals, environments and people
natural state view
-ideal environment for a particular species
-AW may be compromised depending on how far its immediate conditions differ form original wild state
concept of AW is a framework of what three concepts to explain AW
biological function, affective state and natural state view
sentience
animals are recognized as sentient; awareness, sensation, consciousness, sense, perception, alertness
five freedoms vs 5 domains
freedom from hunger and thirst: nutrition
freedom from discomfort: environment
freedom from pain, injury and disease: health
freedom to express normal behaviour: behaviour
freedom from fear and distress: mental state
early AW focus was on ensuring absence of negative experience, now shifting to:
importance of positive experiences
AW is a spectrum
positive and negative, not all suffering is bad, AW changes throughout the day
values
deeply held personal principles that reflect what you believe to be correct, important, desirable
morals
value judgements or beliefs about right or wrong, good or bad
