Q

what are the 3 primary measures of animal welfare

A
  1. behavioral
  2. applied
  3. technical
2
Q

what are behavioral measures

A

the assessment of the occurrence of of specific behaviors

3
Q

applied measures

A

quickly measurable assessments that are typically visual in nature

4
Q

technical measures

A

direct measurements of physiological or environmental factors associated with animal welfare

5
Q

what are the 5 requirements for accurate welfare assessment

A
  1. measurement must be OBJECTIVE, which means unaltered by emotion of personal prejudice
  2. the variables that are measured must be RELATED to the species and welfare state under concern
  3. the impact of human presence and restraint stress must be accounted for
  4. must be able to clearly see the sampling unit at all times
  5. must not create a sampling bias
6
Q

what is an ethogram

A

a dictionary of the names and descriptions of all the behavioral patterns that constitute a species behavioral repertoire

7
Q

3 major behavior sampling methods

A
  1. focal
  2. scan
  3. time
8
Q

when are avoidance tests used

A

used to assess fear of factors associated with negative experiences
-they measure the distance an animal keeps from an approaching person

9
Q

what is confounding

A

a situation where a dependent variable is influenced by external conditions such that the true effects of an independent variables cannot be isolated

10
Q

what are applied measures used for and why

A

auditing because:

  1. quick to measure
  2. repeatable
  3. outcome based variables
  4. animal based assessments
11
Q

what are the 4 common applied measurements

A
  1. coat, skin, feather condition
  2. body condition
  3. locomotion/lameness
  4. wounds/lesions
12
Q

what might the coat skin and feather assessment prove

A

may indicate flaw in management or the presence of disease states

13
Q

what does body condition assess

A

the fatness and thinness

-based on the visibility of skeletal structures through the skin or hide

14
Q

what does the locomotion/lameness score assess

A

measures the ease or difficulty an animal has when walking

15
Q

wound lesion scoring

A

indicates the prevalence and or severity of wounds or lesions on the body which could be multiple factors:

  • handling
  • facility
  • genetic predisposition
16
Q

characteristics of technical measures

A
  • generally precise and highly objective
  • more costly than behavioral or applied measures
  • focus heavily on physiology and biochemistry
  • difficult to conduct in field conditions
17
Q

2 common technical measures

A
  1. hormones: cortisol and epinephrine
  2. metabolites: glucose and lactate
    (fight or flight)
18
Q

what is the fight or flight response

A
  1. stimulation of the sympathetic division of the autonomic nervous system
19
Q

2 types of stress

A
  1. distress

2. eustress

20
Q

order of occurrence for the fight or flight response

A
  1. stressful stimulus
  2. activation of amygdala and hypothalamus
  3. CRF or CRH released
  4. anterior pituitary secretes ACTH
  5. adrenal gland secretes epinephrine and cortisol
  6. physiology changes occur
21
Q

how is the glucose and lactate measurement measured and what are the end results

A
  1. measured by enzymatic digestion

2. end results of reactions create color or changes in electrical conductivity

22
Q

when handling animals, the most important factor to account for is

A

the animals status on the food chain

23
Q

can the body tell the difference between the 2 types of stress

A

no, but the brain can differentiate

24
Q

Epinephrine and cortisol are released into the blood. This causes what to increase

A

blood glucose

25
Q

when does lactate form

A

forms if the metabolic rate exceeds oxygen supply

26
Q

define HPA axis

A

emotional responses trigger hormone release cascade called the Hypothalamic pituitary adrenal axis

27
Q

what 2 chemical responses to stress are almost identical

A

cortisol and lactate

28
Q

what is the objective of animal handling

A

manipulation of animal behavior through visual, auditory, and or physical stimuli and learned behaviors to produce a desired outcome

29
Q

how long does it take for an excited animal to calm down

A

20-30 minutes

30
Q

what are 5 ways the flight zone of an animal is impacted

A
  1. genetics
  2. handling history
  3. size
  4. pregnancy status
  5. familiarity with enivornment
31
Q

where is the point of balance

A

point of balance is located between the shoulder and eye of the animal

32
Q

what are 4 reasons painful procedures are used

A
  1. increased safety (dehorning)
  2. treatment of injury and disease (tail docking pigs)
  3. production of desirable products (castration)
  4. idetification
33
Q

what are the 2 categories of painful procedures
