Proportions of broiler footpad scores throughout the 42-day grow period. Scores were taken at 20, 27, 35, and 42 d of age on approximately 30% of birds in each diet x litter treatment group (N = 192; except N = 48 for day 42). Scores of 1 and 2 indicate mild to severe lesions and ulceration, dark papillae, or bumble foot and the presence of footpad dermatitis. Scores of 0 are ideal and represent minimal changes to the foot. Green is best followed by yellow then red. D 27 and 35 represent differences (P < 0.05) for the wet litter treatment group.
