? - Welfare ethics concerns how humans should treat
animals??????????????? - Welfare law concerns how humans must treat
animals???????????????

??????????? - Some presentations focus on 1 aspect e.g.
- ??????????
- Science physiological indicators ????????
- Ethics introduction to ethics ???????

- Other presentations cover all 3 aspects e.g.
????????? - Farm animal husbandry ??????

- Naturalness??

- Physical??
- ?????????
- Mental??
- Frustration? ???
- Pain from mouth injuries????????
11Three welfare definitions??????
- Physical status (fitness) ?????(??)
- Biological indicators including reproduction and
production????????????? - Mental status (feelings)?????
- Positive and negative emotional states??????????
- Naturalness (telos)??(?????)
12Definitions Physical status???????
- Fraser Broom, (1990)Welfare defines the state
of an animal as regards its attempts to cope with
its environment. ???????????????? - McGlone, (1993)I suggest that an animal is in a
poor state of welfare only when physiological
systems are disturbed to the point that survival
or reproduction are impaired. ????????????????????
??????????? - Moberg, (1985)..the only defensible measurement
of well-being in animals is to determine if the
animal is suffering from stress. Furthermore, I
believe that the most appropriate indicator of
stress is the appearance of a pre-pathological
state.??????????????????????????,????,????????????
??????????? ?
13Definitions Mental status???????
- Duncan(1993)?????????????????????????????????????
??? (..neither health nor lack of stress nor
fitness is necessary and/or sufficient to
conclude that an animal has good welfare. Welfare
is dependent upon what animals feel. ) - Dawkins (1988) ?????????????????,?????????????(To
be concerned about animal welfare is to be
concerned with the subjective feelings of
animals, particularly the unpleasant subjective
feelings of suffering and pain.) - Bentheam (1789) ???????????,???????,?????????(The
question is not, can they reason? Nor, can they
talk? But, can they suffer?)
14Definitions Naturalness???????
- Rollin, (1993)???????????????,???????????????,???
???(Not only will welfare mean control of pain
and suffering, it will also entail nurturing and
fulfilment of the animals nature, which I call
telos.)(??telos??????) - Brambell, (1965) ???,????????????????????????????
?????????(In principle, we disapprove of a degree
of confinement of an animal which necessarily
frustrates most of the major activities which
make up its natural behaviour.. ) - Kiley-Worthington, (1989) ????????????????,?????
????????????,?????????(If we believe in
evolution in order to avoid suffering, it is
necessary over a period of time for the animal to
perform all the behaviours in its repertoire
because it is all functional )
15Relationship between the three definitions????????
?
?????????????
Natural Behaviour
Mental Suffering
?????
?????
Physical Fitness
?????
16Combined definition?????
- Some definitions combine two or three aspects
e.g.??????????????????? - Welfare consists of the combined state of the
animals mind and body, and the extent to which
its nature is satisfied ?????????????????????????
?? - Fit and feeling good ????????(Webster 2005)
- The Five Freedoms (Farm Animal Welfare Council,
1992) are often used as a framework to assess
animal welfare????(????????1992)?????????????? - ???????(hunger and thirst)???
- ????(discomfort)???
- ???????(pain, injury and disease)???
- ???????(express normal behaviour)???
- ???????(fear and distress)???
17The concept of needs?????
- Need a requirement, fundamental in the biology
of the animal, to obtain a particular resource or
respond to a particular environmental or bodily
stimulus (Broom Johnson, 1993)????????????????,
???????????????????????? - If a need is not met, this will affect physiology
or behaviour. E.g.?????????,????????? - If you can link a physiological sign to the
absence of a certain resource, the animal lacks
humane care in that area??????????????????,???????
?????????
18Hierarchy of needs???????
- Some needs may be more important than others
????????????? - Provision of food and water is a fundamental
need??????????????? - Provision of a comfortable lying area may be
less fundamental??????????????? - ?????? gt ?????? gt ?????? (Hurnik Lehman,
1985)
19Needs e.g. legislation?????
- The owner and keeper of the animals shall have
regard to their physiological and ethological
(behaviour) needs in accordance with established
experience and scientific knowledge??????????????
?????????????? - Council of Europe (1976)
- ????(1976)
20Welfare versus death???????
- Welfare concerns the quality of animal life
- ???????????????
- Death affects the quantity of animal life
- ????????????(??)
- Quality and quantity of life may be ethical
concerns????????????????
21When is death relevant to welfare????????????????
- The manner of death is relevant
- ?????????
- e.g. method of slaughter is important
- ????????
- High death rates can indicate poor welfare
conditions - ?????????????
- Poor husbandry conditions can cause disease and
death?????????????????
22AnthropomorphismShould we assign human
attributes to animals????????????
- Humans are animals with similar
biology???????????? - However, each type of animal has different
behavioural needs???????????????? - Using a human-based assessment may be a useful
first step ??????????????????? - This assessment must be qualified with the
individual animals needs???????????????
23Conclusions / Summary??/??
- It is important to distinguish between the
various components of animal welfare
???????????????---???????? - Science
- Ethics
- Legislation
- Animal welfare definitions are derived from three
basic concepts ???????????????---???????? - Physical
- Mental
- Natural
