Footpad Dermatitis. The same birds tested for GS
were also examined for footpad dermatitis using the
technique of Ekstrand et al. (1998). The footpad of
the left foot was examined. A score of 0 represents a
healthy footpad with no demarcation, whereas a score
of 2 represents a severe lesion. The data were expressed
as an average footpad score and as a percentage of birds
falling within each score category.
