exam (after midterm) Flashcards
**welfare inputs
measure of environment and resources, resource based measurements.
includes management, envrionment, animal genetics, early life experience
welfare outputs
animal responses, animal based measurements
includes behaviour, physiology, clinical health, production
welfare indicators (2)
- practicability - time constraints, expenses, handling, observation
- reliability - repeatability and validity
** inputs for welfare - meaning of management
stockman training, time they have to care for animals
how many animals 1 person is taking care of
** inputs for welfare - meaning of environment/housing
kind of housing, quality/amount of animals, use of vaccines
** inputs for welfare - meaning of genetics/early life
genetic makeup and early experience affects disease resistance and fear thresholds.
4 applications for group assessment
- research - health/welfare monitoring, impact of interventions
- voluntary certification schemes
- legislation/ codes of practice
- advisory - preventative medicine
2 groups of analgesics
- opioids (narcotics)
2. non-steroidal Anti-Inflamitory Drugs (NSAIDs)
why is pain often not recognized in vet practice
use ranges 84-17% bc od difficulty recognizing pain, lack of knowledge abt appropriate therapy
what is pain
unpleasant sensory/emotional experience w critical/potential tissue damage
- either physical hurt/discomfort caused by injury or emotional suffering
function of pain
alarm system that alerts organism to take action to avoid or minimize injury
why do animals change their physiology when in pain
- reduce/avoid damage
- reduce likelihood of recurrence
- promote recovery
most frequent injury areas
foot and leg most frequent
inflammatory pain
greatest cause of pain in vertebrates- external trigger.
ischaemic pain
bc of lack of blood from pressure on artery. like Maddy’s toe
electrical shock pain
direct activation of nerves near content point, causes muscle contraction
facial expression of pain
used often in infants.
can’t use it as full justification for animals - anthrophomiphism
attentional shifts altering preception
motivational change acts by way of refocussing attention
challenges w pain management on farm
limited factors for pain management (assessment, availability, lack of clinical trails, withdrawn times)
reasons for castration
reduce aggression improve safety reduce sexual behaviour avoid unwanted pregnancy improve meat quality
tail docking
on sheep, cows, pigs, dogs, usually w/o anasthetic
procedural or post-procedural pain
dehorning
removing horn and horn producing tissue
beak trimming
reduces mortality and morbidity, acute and chronic pain. considered mutilation.
muelsing
removing skin fold w knife to prevent parasite infestation
how does physical environment affect welfare
preventing performance of behaviours, unstimulating, increased likelihood of disease, damaging/injuring animals, causing discomfort, frightening animals
code of practice for hens and pullets
all new housing systems must support nesting, perching, and foraging behaviour. all hens must have enriched cage
internal parasite impact
reduce growth, may delay sexual maturity, may reduce milk production
external parasite impact
transmit pathogens, disturb feeding time, reduce milk production
how to judge truck designs for pigs
loading and unloading behaviour
temp on truck
behaviour during lariage
meat quality
humane slaughter
animals must be stunned before blood removed
stunning induces unconsciousness asap
when stunning is done, animal does not feel pain.
captive bolt stunning
penetrative- more effective, lower chance of effort
non-prenatrative - may not fracture skull
electrical stunning
widely used in pigs and chickens
can cause blood speckle and splash
animal needs to be restrained, potential to be incorrectly stunned
CO2 stunning
pigs respond badly, loss of consciousness 33-47 sec
loss of posture after 10 sec. 80-95% CO2
quality assurance/farm assurance programmes
private companies/ producers etc, focus on food safety and welfare- marketing
health of animals act
1990
enabling act- authorizes making regulations
aimed to protect can livestock from contagious diseases
health of animals regulations
disease control, quarantine and disposal import and export of animals and products transport and feeding whilst protects animals from suffering requires animal to be fit for transport
PAWS act
provincial to protect animals toughest penalties in can more inspections basic standard of care for all animals
limitations to legislation
needs to be effective, enforceable, and economically feasable
private initiatives marketed well giving more money
National Farm Animal Care Council
codes of practice development process
Animal care assessment model
suitable pet criteria
no risk of harm to community/environment
adequately meet needs of species in captivity
suitable interactions w humans to ensure continued commitment
animal characteristics to consider when picking an animal
breed
age
source
adopt dont shop
bullshit rule not feasible for many, shortage of dogs, lots of behavioural problems etc
common everyday companion animal welfare issues
behavioural needs
behaviour problems
inappropriate training methods
medically unnecessarily procedures
positive reinforcement
give treat, increase behaviour
negative reinforcement
remove pressure as a reward
positive punishment
decease behavoiur by punishing
negative punishment
remove attention - looking away from dog to stop jumping
when is use of animals acceptable in research, tech and testing?
- contributes to understanding of fundamental biological principles
- knowledge developed reasonably expected to benefit humans/animals
- merit review is approved
- best effort to find alternatives have failed
morals
concerned w right and wring, something is moral if it pertains to right rather than wrong
3 R’s for animal use
Replacement- avoid/replace animal use
Reduction- strategies that result in fewer animals being used
Refinement- modified husbandry/experimental procedures to minimizer pain and distress/enhance welfare
commitment to change
most value at 75% commitment
4 pillars of wildlife rehab
wildlife rehab medicine
conservation education
new discoveries
emergency preparedness and response
3 reasons why we come across wildlife
- sick
- orphan/kidnapped
- injured (pollution, cars)
human-wildlife conflicts
pollution, vehicle, boating/fishing, persecution, habitat loss, toxicosis, hunting/trapping, sticky stuff
animal welfare concerns in wildlife
husbandry, nutrition, enrichment, stress, skills/resources, pain management, chance for release?
problems inflicted on animals during rehab
aspergillosis, aspiration pneumonia, illness/anorexia bc of husbandry, carpal/keel injury, feather injuries, bumble foot, thermal burns, lacerations, metabolic issues
classifications for animals based on use
companion, wild, and utility animals
utility animals
food, research, working, sport.
domestic animals kept for utility purpose, various roles.
emotional relations can vary and overlap
world organization for animal health*
OIE
helps the need to fight animal disease at global level, responsible for improving animal health, referenced by WTO
*OIE standards for terrestrial animals
transport slaughter use in research and education stray population control working horses production animals
*OIE sandards for farmed fish
transport and slaughter
impact of world trade organization on animal welfare
legally binding trade agreement to encourage free trade
products are treated equally,
a country can ban use of something and still import it
EU animal welfare legislation
1999- 1st time animals were regarded as beings w feelings that can suffer and experience well-being
*legislation that governs treatment of farm animals in canada?
no
*3 laws that apply to welfare of food animals in can
health of animals act
meat inspection act
criminal code
how christians view animals and importance for their religion
not traditionally sympathetic to animals, we have dominion over them.
how islam view animals and importance for their religion
belief in 1 god, promotes kindness for living creatures, all creatures are like family to God
how hindus view animals and importance for their religion
many gods, some animals considered “sacred”, used in ceremonies “holy cow”
animal welfare issues w sacred animals
cows can be prevented from slaughter, some need to travel long distance to be slaughtered, may cause unneeded suffering for animal who’s best outcome is slaughter
religious states may alter wild behaviours, animals dependent on ppl food
animal sacrifices
classical conditioning
like pavlov - stim paired w neutral
operant conditioning
learn to behave to get rewards and avoid punishment
5 freedoms
- freedom from hunger and thirst
- freedom from discomfort
- freedom from pain, injury and disease
- freedom to express normal behavoiur
- freedom from fear and distress
- combines all criteria, does not include the freedom from death
5 revisions to 5 freedoms for production animals
- good nutrition - diet to maintain health and vigour
- good environment - suitable housing, good air, comfy bed
- good health - vet care
- appropriate behaviour
- positive mental experiences
3 criteria forming the basis of welfare definitions *
physical, mental, natural/behavioural
3 elements in welfare debate *MC Q
- science - effects on animal from animal perspective
- ethics - human action towards animal
- law - result of science + ethics dictating how humans must treat animals (codes of practice
phenomenal consciousness
sentience
how we understand other minds, what is it like to be someone else
refers to other aspects of consciousness
