    Tacit ethical judgement.
  2. What are the five views about humanities duty's to animals?
    • Contractiarianism
    • Utilitarianism
    • Animal rights view
    • Contextual approach
    • Respect for nature
  3. What is Contractarianism?
    • It is a human-centered view on humanity's duties to animals. 
    • People should be moral because of self-interest
    • - This means that a person needs only treat animals well enough to satisfy their own self-interest.
    • To be part of a moral community, contracts have to be formed.  Animals can't form contracts so they are excluded from community.
  4. What does contractarianism say about contracts?
    Animals can not form contracts, and to be part of a community, individuals need to enter into a contract which animals can not.  Therefore, animals are not part of the community.
  5. What is utilitarianism?
    • Only consequences are important when making ethical decisions
    • -consequences for all parties
    • There are two types of consequences
    • -Maximize pleasure and minimize pain
    • -Can painlessly kill animals as long as they've lived happy live and there are more to replace them
  6. Who is Jeremy Bentham? What did he say?
    Jeremy Bentham created one of the consequence types of utilitarianism.

    He stated that the goal of utilitarianism is to maximize pleasure and minimize pain.  He said humans and animals both can feel pain, so their interests deserve equal concern.
  7. Who is Michael Lockwood?  What did he say?
    Michael Lockwood created one of the consequence types of utilitarianism.

    • He stated that humans can painlessly kill animals as long as they've lived happy lives and there are more to replace them.
    • Animals must have self-consciousness if it can go on living.
  8. What is the Animal Rights View similar too?
    Biocentrism.
  9. What opposes utilitarianism?
    Animal Rights View
  10. What is the Animal Rights View?
    • Argue that animals have moral rights
    • Rights are based on capacity/sentience/self-awareness, not genes
    • beings have inherent value and they want+prefer things, believe+feel, recall+expect, feel pain + pleasure, satisfaction + frustration

    Killing is harm by deprivation
  11. According to the Animal Rights View, what should be abolished?

    Helps to prevent or reduce the incidence of aberrant behaviours
  169. What is biological relevance?
    The enrichment must fulfill a behavioural need
  170. What is CFO? why is it bad?
    • CFO is confined feeding operation

  177. Who defined stereotypies?
    Fran Odberg
  178. What are the three requirements of a stereotypie?

    • Weaving
  182. What are examples of stereotypies and vices in sheep?
    • Fleece pulling
    • Wood chewing
  183. What are some examples of common causes for stereotypies?
    • Stress
    • Hunger
    • Overcrowding
    • Boredom
    • Confinement
    • Barren environment
    • Temperature
  184. What are the traditional indicators of well being?
    • Growth
    • Reproduction
  185. Does economic performance equal biological performance? explain?
    Increasing stocking density might increase mortality per bird, and decrease well being but the total number eggs per cage increases and feed cost decreases.
  186. What is the traditional role of the bet?
    • Treat injuries, infections and diseases
    • Reduce disease through herd health programs
    • Provide pain control
    • Advise and educate on nutrition, housing and handling etc.
    • Advocate for human care
  187. What is important to consider with animal pain?
    • It should not be confused with human pain
    • Animal pain serves many of the same purposes as human pain and is important to the animal
    • The experiences of pain may not be identical between animal and human
  188. What is the definition of animal pain?
    • An aversive sensory experience that elicits protective motor actions
    • Results in learned avoidance
    • May modify species specific traits (social behavior, behavior) to reduce likelihood of occurrence. 
  189. What are the different types of pain classified by duration? (3) describe each
    • Acute: Immediate on stimulation of nociceptors
    • Chronic inflammatory pain: Occurs when healing persists beyond expected time (inflammation)
    • Chronic neuropathic pain: Intractable pain
  190. What is nociception?
    The detection of a noxious stimulus
  191. What is pain? Where does it occur?
    Pain is an experience which is responsible for the mental processing of noxious stimulus, it occurs in the brain. 
  192. What are nociceptors?
    Nerves which generate electrical signals that travel along nerve fibers to the spinal cord
  193. What is the peripheral and central mechanisms of nociception?
    • Peripheral: skin, bone, muscle and other tissues and consciously occurs
    • Central: The grey matter of the spinal cord.  Pathway from spine to brain. 
  194. What is the difference between reflex and pain sensation?
    • Reflex occurs in the absence of CNS transmission
    • Pain is achieved through relays in the brain after processing the somato-sensory parts of the cerebral cortex
  195. What is breakthrough pain?
    The pain that remains after animals reduce the severity of their own pain through coping mechanisms
  196. Describe the assessment of animal pain?
    • Direct measurement of an animals pain is not possible. 
    • It is a value judgment relying on measurement of physiological and behavioral changes (indices)
  197. What are 6 things we can look at to asses pain in animals?
    • Postural responses to pain
    • Gait
    • Activity
    • Vocalization
    • Mental State
    • Evoked Behaviour
  198. What are some postural responses to pain? (6)
    • Lying on side
    • Dog-sitting
    • Praying
    • Stretching
    • Saw horse stance
    • Head pressing
  199. What do we look at regarding gait to asses animal behavior?
    • Lameness-limping
    • May use scoring (1=sound through 5=severe lameness)
  200. What do we use to measure mental state in an animal?
    BAR" Aware, bright, alert and responsive
  201. What is evoked behavior? How can it be used to asses pain in an animal
    • It is an animals response to standard stimuli. 
    • Wildlife that allow humans to approach them exhibit a modified evoked behavior, and may be ill. 
  202. How can analgesics be used as a diagnostic tool?
    The use of analgesic or anti-inflammatory drugs to reduce or eliminate signs of pain can provide evidence, which confirms the presence of pain
  203. What are some options to relieve pain in animals? (4)
    • Opiods
    • Anti-inflammatory
    • Local anesthesia
    • Analgesics
  204. What is the relationship between welfare and disease
    • Disease is an indicator of poor welfare
    • Poor welfare does not necessarily lead to disease
  205. What is stress
    An environmental effect on an individual that overtaxes its control systems and results in adverse consequences and eventually reduced fitness
  206. What is the pre-pathological model? Provide an example using thermal stress.
    • Behavior response =>Physiological response => pre-pathological state => pathological state
    • Huddling => Shivering => weight loss, disease => death
