Footpad dermatitis is an inflammation of the skin that affects the surface of the sole of the foot, the skin of the tarsal joint and, in severe cases, the bone of the pectoral keel. It is a multicausal pathology in which the environment, nutrition and intestinal integrity are involved. It affects animal welfare and generates economic losses due to confiscation during slaughtering. The objective of this work was to evaluate the plantar lesions in 40-day-old Cobb 500 chickens, housed in two production systems: new litter (NL) and litter used in four periods (UL). It was observed that 77% of the animals housed in NL did not present lesions, and 23% presented lesions of grade 1 or 2. On the other hand, 28% of the animals housed in UL did not present lesions, while 72% presented lesions of grade 1 or 2. The percentages of lesions found in both groups were significantly different (p<0.001), pointing out that animals located on UL are 8.6 times more likely to present lesions of greater degree than those housed on a new bed.
