     1        serves more than one purpose?
     2        A.  I think there is a greater prevalence of certain types
     3        of disorder and it is very difficult to say that one type
     4        suffers more than the other because they actually get
     5        different disorders.
     6
     7   Q.   What I was leading up to is this, can one say there is a
     8        greater concern about about leg problems in broilers
     9        because they are bigger birds and there is a greater weight
    10        to be carried by their legs, or is that a gross over
    11        simplification?
    12        A.  I think it is certainly true to say that, but it is
    13        rather oversimplifying the fact because egg layers can
    14        suffer from other disorders.

    16   MR. JUSTICE BELL:  Thank you.
    17
    18             Cross-examined by the Defendants, continued.
    19
    20   MR. MORRIS:  Dr. Gregory did give quite a lot of evidence on
         that.
    22
    23   MR. JUSTICE BELL:  I wanted to know what Dr. Pattison's view is.
    24
    25   MS. STEEL:  When you are talking about egg layers suffering from
    26        other disorders, is that particular disorders that battery
    27        chickens suffer from as a result of having to lay so many
    28        eggs?
    29        A.  The condition of osteoporosis in egg layer chickens
    30        which are kept in battery cages is a well-known condition.
    31
    32   Q.   You said that there is a greater prevalence of certain
    33        types of disorder in broiler chickens.  If we look at
    34        comparable age groups, would there be a much greater
    35        incidence of leg problems in broilers than there would be
    36        in a farmyard chicken, for example?
    37        A.  If you are comparing age for age, yes, there are more
    38        leg problems in broilers.
    39
    40   Q.   Considerably more?
         A.  Yes.
    42
    43   Q.   Could you get Gregory's orange bundle, but I am not sure
    44        what number it is.
    45
    46   MR. RAMPTON:  V.
    47
    48   MS. STEEL:  Thank you, bundle V.  If you could turn to tab J,
    49        please?  If you look at page 193, the chart on the top of
    50        the page, and if you look at the breeds on the right-hand 
    51        side? 
    52        A.  Yes. 
    53
    54   Q.   You see "breed D"?
    55        A.  Yes.
    56
    57   Q.    Has a much lower prevalence of leg problems?
    58        A.  Yes.
    59
    60   Q.   It has got very low gait scores.  If you turn to page 192,
