Q

What 6 characteristics does a welfare assessment have?

A

1) They were all made by an author and/or an organisation
2) They should have an aim and/or purpose
3) They should also have aspects of welfare to capture
4) Welfare assessments also need practical considerations

Q

How do you apply a welfare assessment to a population of animals?

A

You look at a proportion of the population
That proportion of the population will then be used as a representative sample of the entire population to make a generalised assessment of the entire populations welfare state

Q

Q

Depending on the aim of the assessment you’ll have what 3 things?

A

1) Differing indicators to meet the aim
2) Differing labour demands based on the indicator and what needs to happen to ensure they work
3) Differing reliability of the measures in relation to timeframes

Q

It is always important to remember the underlying biology of the indicators in terms of what 3 things?

A

Predictions of changes you anticipate
Timeframe
The function of what you’re measuring

20
Q

What 3 things do you need to be aware of in terms of logistics when selecting a welfare indicator?

A

You need to be aware of how much time you have

You need to be aware of how much money it will cost

You need to be aware of how much technical expertise is needed to do the assessment

21
Q

What 2 things are important when looking at the ethical considerations and relevance when selecting a welfare indicator?

A

Invasiveness

Intrusiveness
Causing disruption or annoyance through being unwelcome or uninvited

22
Q

If the indicator is a surgical implantation for scientific research with no other alternatives the indicator would also need to be assessed under what law?

A

The Animal Scientific Procedures Act

23
Q

What can intrusive assessments do?

A

Change behaviour
Disrupt behaviour and emotional states
Cause fear

24
Q

If the welfare assessment is intrusive then what needs to be done?

A

If the assessment is intrusive then the animal needs to be habituated to it
This is done to ensure that the data collected is representative of the welfare in the desired context and not representative of how animals welfare is affected by the assessment itself

25
Q

What type of welfare indicators can anyone use?

A

Subjective and low tech indicators

26
Q

Due to subjective low tech indicators being able to be used by anyone they are what?

A

Cheaper

Able to capture subtleties that objective measures can’t

27
Q

Give examples of subjective low tech measures

A

Scoring scale
Qualitative Behavioural Assessments
Body condition scores

28
Q

Most objective low tech indicators are what type of indicator?

A

Resource based indicators

29
Q

What is a disadvantage of objective low tech behaviour indicators?

A

They can be time consuming

30
Q

Give examples of objective low tech indicators?

A

Resource based indicators
Behavioural indicators
Physical indicators
Visible bodily secretions

31
Q

For an objective low tech indicator to be objective what must you do?

A

For these types of indicators to be objective you just measure, or score their presence or absence

32
Q

Name some objective high tech indicators?

A 
Resource based indicators
Behavioural indicators
Hormones
Biochemistry
Neurotransmitters
Pathologies
33
Q

What is the disadvantage of using objective high tech indicators?

A

They require:

       - Expensive equipment
       - Delicate equipment
       - training to use the equipment
34
Q

True or false

We can use a combination of subjective and objective methods to measure many indicators

A

True

35
Q

What do welfare measurements need?

A

Welfare indicators should be valid

Welfare indicators need to be reliable

Welfare indicators also need to be sufficiently sensitive to capture changes, or differences, between populations

36
Q

Who created the Welfare Quality assessment?

A

The Welfare Quality assessment was created by a European research project focussing on harmonising the animal welfare standards across the human food chain

37
Q

What were the aims of the Welfare Quality assessment?

A

The research group looked at the welfare of farm animals during their rearing, transport and slaughter

The research group wanted to be able to give feedback and advice to producers so changes can be made

The researchers wanted to also provide a quality monitoring aspect to the human food chain to provide welfare information for retailers and consumers

38
Q

What are the 4 domains of the Welfare Principals?

A

Good feeding
Good housing
Good health
Appropriate behaviour

39
Q

What are the Welfare Principals good feeding principles 2 sub-principles?

A

Absence of prolonged hunger

Absence of prolonged thirst

40
Q

What are the Welfare Principals good housing principla’s 3 sub-principles?

A

Comfort around resting
Thermal comfort
Ease of movement

41
Q

What are the Welfare Principals good health principla’s 3 sub-principles?

A

Absence of injuries
Absence of disease
Absence of pain induced by management procedures

42
Q

What are the Welfare Principals appropriate behaviour principla’s 4 sub-principles?

A

Expression of social behaviours
Expression of other behaviours
Good human-animal relationships
Positive emotional state

43
Q

How do you process data from the Welfare Principals?

A

First you’d gather data from 30-50 measures
You’ll then convert all the data into sub-principle scores
The different sub-principle scores are then combined to form principal scores
After that an overall assess of welfare is done
How good the welfare standards present are then displayed on a scale of 0-100
0 = worst situation you can find on a unit
50 = neutral
100 = best situation possible

44
Q

True or false

Decision trees are generally used for data taken on a farm

A

True

45
Q

Getting principal scores from sub-principle scores involves the calculation of a type of weighted mean known as a choquet integral
Why do you need choquet integrals?

A

By converting the data into choquet integrals it makes all the scores equal to each other, so that they won’t affect each other when turned into principle scores

46
Q

What are the 7 criticisms of Welfare Quality assessment?

A

It’s time consuming
The larger the herd the longer it takes

Even though the data has been weighted a few severely affected animals can go unnoticed

Some of the data weightings are based on assumptions

Inter-observer reliability can be hard to achieve on farms

Can 1 aspect of welfare truly compensate for poor welfare in another?

How are problems communicated to ensure practical solutions are done to improve welfare standards

With the Welfare Quality assessment what can be classed as a good welfare assessment has a very low baseline

47
Q

What makes up the Welfare Quality assessment?

A

Welfare Principals

Qualitative Behavioural Assessments
