MR RICHARD
WEST
Earl of Onslow
20. Can I come back to Dr Jennings' remarks.
She said there was a difference between the health of an animal
and its sociological wellbeing. She also said there were differences
in the principles of animal welfare in different parts of the
world. First of all, I will use the anecdote of a racehorse. There
is no way if you stick a racehorse in a box and it has to run
three, three and a half miles at Epsom, an immature horse with
a crippled jockey on top of it, that that is in tune with the
sociological habits of wild horses. I find this concept quite
difficult to differentiate between sociological welfare and the
health of the animal. Secondly, you say that the principles of
animal welfare are different in country A to country B, but how
do we know that our principles are superior to those of somebody
else? (Reverend Professor Banner) Can I just help my
colleague by giving a lay person's example which I found very
striking on visiting a laboratory last year. We were shown rats
caged, singly or in twos. If you drop a piece of food into a cage
with two ratsit was not doneI am assured that they
would almost kill one another. On the other hand, if you put 30
rats in a large case you can drop a piece of food inthey
will have established a social systemand the dominant rat
will take the food, there will be no squabble about it, and to
the lay person they are much easier to handle and so on. I think
that is the sort of social needs difference that good laboratory
practice is sensitive to. To a lay person that was a very striking
example.
21. I remember my father saying that about rat
catchers, that if you put a terrier in a corn bin and if there
were lots of them they would all run into the corner until there
were only two left and then there would be a punch-up. I am trying
to get to the root of this whole moral question as to what questions
we are asking. It is not an easy question, I do not think, that
is why I am picking up on what could be regarded as esoteric questions.
I am still not happy because I do not understand the answer and,
frankly, I do not know what the answer is myself. (Reverend
Professor Banner) There is a distinction, I take it, to be
drawn between morally how important an animal's welfare is and
how one establishes welfare. About the establishment of welfare,
there are detailed scientific disputes and the committee only
recently, in looking at a report that will be out very shortly
in relation to biotechnology, was considering the merit of certain
tests of welfare and whether they really did show better welfare
or not. Obviously on the establishment of whether it is poor or
good welfare, some of it might be obvious, there are some fine
judgments to be made which are backed by scientific reason of
a persuasive or unpersuasive sort depending on your estimation
of it. You are absolutely right to say that one has to be very
sensitive to the question of how welfare is established and what
is supposed to be good welfare is often not good welfare. What
one thinks might be kind to an animal is not the same as what
constitutes it. (Dr Jennings) I would like to emphasise
the very big difference between health, health on its own, and
the overall welfare of the animal because I think that is really
crucially important. Health is a part of welfare. You will not
have an animal with good welfare if it is not healthy. The word
"health" tends to encompass physical health but this
is not the sole consideration. Another very simple example, I
think, is if you look at the husbandry of rabbits in laboratories.
In the past, and still in a lot of laboratories, rabbits would
be kept in a cage, they would be given food and water and they
would be kept clean, and their health would be fine by most of
the parameters by which you would examine these animals. However,
rabbits are social animals: they do not spend all their time sitting
in a barren cage, they spend their life doing things. The Farm
Animal Welfare Council drew out the principles of the five freedoms,
one of which says that the animal should have freedom to perform
most of its natural behaviours. If you give a rabbit its freedom
to perform its natural behaviour, it wants to hop around and jump
all over
Earl of Onslow: We all know about rabbits!
Chairman
22. I think we should follow the illustration
of more than two rats where possibly the presiding rat can allocate
rations fairly. (Dr Jennings) If you are going to keep
animals for experimental purposes you cannot just consider health,
you have to consider their overall welfare and consider their
social and behaviourial needs as well.
Lord Hunt of Chesterton
23. Could I just pick up that point and go back
to the first question from Lord Onslow. It seems as if you have
been talking about these animal welfare issues involved in agriculture
and welfare issues involved in animal experimentation, and you
operate entirely within a statute associated with animal procedures.
There are other statutes and Acts to do with agriculture and there
are many aspects of agriculture, battery chickens and so on, that
people are concerned about. Is there some connection between these
two areas? Are the definitions of welfare used the same for you
as when you operate for MAFF, or are we really talking about two
completely different areas? (Reverend Professor Banner)
As you say, they are different statutory responsibilities. The
Farm Animal Welfare Council has a responsibility for advising
on the welfare of farm animals. The Scientific studies which have
been done which relate to welfare are relevant to the work of
those who are concerned with both, although of course the particularities
of the experiments and studies may vary. The question of the definition
of welfare came up previously. The word which is key for the committee
on the legislation is cost. One of the costs to the animals may
be in harm in a very obvious sense although that could be a harm
to welfare. Yes, we consider it. It is not a word that we grapple
with the definition of but we would be concerned with the scientific
evidence for good and bad welfare.
Earl of Onslow
24. You say you do not grapple with the meaning
of the word welfare (Reverend Professor Banner)
The definition.
25. But you then apply scientific rules to it.
How can you apply scientific rules to something which you do not
know the meaning of? (Reverend Professor Banner) I
did not say I did not know the meaning of it, my Lord, I said
we did not grapple with a definition.
26. If you cannot define it ergo by its nature
you do not know the meaning of it. (Reverend Professor
Banner) I would not say that.
27. No, you did not say it. (Reverend
Professor Banner) I said I would not say it.
28. What you said was "I cannot define
welfare". (Reverend Professor Banner) I said we
do not, as a committee.
29. If you do not define it you cannot know
what it means. (Reverend Professor Banner) I would
quibble with you, my Lord. I cannot define night and day but I
know the difference between them.
30. Yes, you can. I am sorry if I am being beastly
and I am sorry if I am giving you a hard time but the point is
unless we get the definition of what we are talking about right
at the beginning we will not get anywhere, we will start producing
waffle. I do not know the answer myself, I do not understand the
answer, that is why I am asking for you lot, who are cleverer
people than me, to give it to me. (Reverend Professor Banner)
A characterisation of welfare has already been given, which is
the ability of an animal to express its normal behaviour and I
would add, I think, to cope with the environment in which it is
placed. I would call that a characterisation, I would not call
it a definition. I would say that characterisation is a working
definition or characterisation which is sufficient to have a meaningful
discussion.
Baroness Warnock
31. I have great sympathy with you saying that
you know what it means but you cannot give a definition of it,
the two things are not incompatible. Surely what is constantly
in the minds of people who are trying to decide whether the welfare
of the animal is being given due consideration is the negative
criteria if it turns out for some inexplicable reason that the
welfare is not good enough, because every species of animal expresses
itself differently and, therefore, you may not know in advance
what behaviour for a particular species of animal is going to
show that its welfare has been overlooked, even if it is healthy.
I absolutely accept that distinction. In a way one does not need
a definition because one just needs criteria for judging whether
the welfare is going down. (Reverend Professor Banner)
Typically that would be so in a licence application where one
would see "end points" or less formally "indications
of poor welfare" which would be a sign of a problem, for
example if an animal becomes withdrawn or declines to eat or starts
pulling out its fur, whatever it might be.
32. That would be a sign that the welfare was
not all it should be. I tend to think that we will be wasting
our time if we try to get a definition that is clear cut because
it is almost a defeasible concept: the animal is okay if it is
behaving as normally as it can and it is not okay if it is showing
signs of distress. Would that not be right? (Reverend Professor
Banner) Can I ask whether my colleague, Professor Purchase,
would like to comment on this because he has an interest and expertise
in this. (Professor Purchase) I recollect about two
years ago we had a retreat for the Animal Procedures Committee
and I think it was Professor Dawkins who made a presentation to
us. The thrust of her presentation was right at the heart of this
question and it was that we should be wary of using anthropomorphic
values and imposing them on the animals and that we should actually
observe the animals. In particular she gave us the example of
the question about battery farming of chickens and said that chickens,
because of their nature of how they live in the wild, might actually
be happier in battery cages than they would be on an open floor
because they were used to being in confined spaces. If that is
the case you have to go and make observations to see whether an
open floor is better than a battery cage, rather than saying "I,
as a human being, would prefer an open floor than a battery cage".
I think that maybe helps in distinguishing the two features.
Lord Lucas
33. I just want to pick up on the remarks of
Professor Banner that he had seen a marked difference in standards.
Who plays the role of Chief Inspector of Prisons and reports on
these and makes them public? (Reverend Professor Banner)
Not the Animal Procedures Committee. I think that would be a matter
in the first instance for the Animal Inspectorate, who are responsible
for granting licences not only for projects and to individual
experimenters but also to establishments, and have a responsibility
for setting standards for good practice. I will just turn to my
Secretary to see whether he wants to add anything. I would not
suggest that standards are not being observed but rather saying
the best practice is much better than the practice which I hope
conforms, and I expect conforms, with the regulations and requirements.
The difference between the very best practice and less good practice
is quite marked to a lay person. (Mr West) That was
my point, there was no suggestion that those lower standards were
in breach of the regulations.
Lord Soulsby of Swaffham Prior
34. I may say, my Lord Chairman, some of this
discussion I have heard before about what welfare is and how you
define it. Perhaps I should declare that I was a member of the
APC in its first four years of existence. What are the current
trends in scientific procedures involving animals? The needs for
technologies have changed substantially over the last ten or 15
years. Has the work of the committee changed over that time under
the Act since it has been in force? Finally, how do you see the
role of the committee changing with the vast changes in biological
sciences that are taking place right now? (Reverend Professor
Banner) I can answer that question by saying I could not relate
all of the changes in the committee and the way it operates to
the biological sciences. If I could separate out those two. There
have been changes in how the committee operates. The present Government
has increased the committee in size and I would say, and as Chairman
I am certainly happy with this, has increased the width and breadth
of representation on the committee so we now have, I would say,
a very wide representation of points of view on the committee.
That is one change in the committee. In terms of how we operate,
and I cannot comment on the early existence of the committee,
I think compared with previous years to my becoming Chairman in
1998, we have become more proactive as a committee, we are taking
on more issues to investigate and identify for ourselves rather
than reacting to events and business that come to us. You will
know that there was a review of the Act[3]
and we have an agenda of investigations of various key areas which
is ongoing. In terms of how our work relates to the changes in
the biological sciences, I might ask my colleague, Professor Purchase,
to comment. One trend up to now has been that the number of animals
used has been decreasing but I think there is every expectation
that will not continue and that the development of genetic modification
and the possibilities that offers for experimenters will mean
that the numbers increase. I am not sure I can suggest immediately
how that will affect the work of the committee. I think the committee
feels that it must be sensitive to developments and adapt its
work as necessary in the light of those developments. I think
that the perception that there will be an increase in the number
of animals used is one which is shared quite widely by the scientific
community.
35. You will have more specifically designed
animals as a result of your ability to do genetic modification
so although the number of animals may go up, the number of nondescript
animals that are not, in fact, specifically designed for the work
will go down, hence your results will be much more meaningful. (Reverend
Professor Banner) I am sure that could be argued, yes. (Professor
Purchase) It would be argued by some, yes.
Chairman
36. Does Professor Purchase want to say anything? (Professor
Purchase) Thank you, my Lord Chairman. It is interesting that
the numbers have been declining over the last more than ten years.
It is equally interesting that I do not know of anyone who has
done a systematic study of why that has happened. I suspect that
if you look at the figures, the majority of reductions have been
made within industry, and I suspect what has happened is that
the pharmaceutical industry has become more efficient in the way
it does its experiments, relying more on modern in vitro
genetic methods rather than using whole animals. I am sure of
that. There is a problem here: it is frequently expressed that
the number of animals used experimentally in some way reflects
the effectiveness of the Act. I would like to say that must be
far from the truth because it does not measure any output. If
the number of animals increases two fold but the research output
increases ten fold then we are in a better position than we were
before. The factors that do influence the number of animals are
the excitement of the research, the opportunity it provides, and
what we are seeing now is an increase in the opportunity provided
by the use of genetically modified animals. The second factor,
which derives from that, is the amount of funding that is being
spent in this area of research. We have seen the big funding agencies
in the UK wanting to exploit the knowledge from genomics, so it
follows that you would expect to see more animals used for that
purpose if animals are the only means of exploiting it. Finally,
it is the way in which the research is done and that comes to
the use of alternatives. I believe that there is pressure on people
to use alternatives, both legislative and moral pressure, and
we will see that continuing. The use of alternatives will not
necessarily reduce the number of animals. (Reverend Professor
Banner) If I could add a very quick supplement to that. It
seems to me what is very important when I talk to people about
this committee and its workI should add as a rider in terms
of our working the Animal Procedures Committee has adopted, along
with other Non-Departmental Public Bodies, use of good practice
in regards to openness and consultation and so onis that
the Act as such gives no purchase to the regulators to reduce
the numbers, except in the key provision that a licence shall
not be granted where an alternative is available. The Act as such
does not give purchase to the regulator to reduce the number of
animals as a total. That is a brief way of saying what Professor
Purchase said more expertly than I can.
Earl of Onslow
37. May I ask a question on the number of animals.
Presumably most animals are rats and mice, is that right? (Reverend
Professor Banner) The majority, my Lord, yes.
38. If you need more animal experiments you
just breed more rats and mice whose sole purpose in this life,
in their short and transient existence, is to be an object of
experimentation. So they only come into existence because somebody
wants to do something to them. Actually, the number of animal
experimentations is not as relevant as if one was going, say,
to capture a wild chimpanzee and do experiments on that. There
does seem to me to be a very serious difference between taking
monkeys out of the wild, which I know there has been some of,
and actually breeding rats and mice. You put a male rat and a
female rat in a cage and lo and behold in a nanosecond you will
have hoards of them. There does seem to me to be a difference
in this numbers game. The numbers game in itself is not really
very relevant. (Reverend Professor Banner) Certainly
there is no mechanism in the Act for controlling or capping the
numbers. Obviously in terms of the different considerations about
costs, as it were
39. I am not asking costs, I am asking a woolly
moral question. (Reverend Professor Banner) I meant
in the wide sense, I did not mean financial. I meant costs in
the sense of harms, burden to the animals.
