“…Perivascular lymph nodes of different sizes and numbers, including coalescent lymph nodes were observed in the dermis (Figure 7). In the study of Santos et al (2002), the severest footpad lesions were observed when broilers were 45 days of age, and with similar gross appearance as in 20-d-old birds. Histologically, large areas of ulceration, superficial diffuse heterophil infiltration and the deposition of large amounts of exudate containing bacterial lumps and remnants of plant material on the surface of the ulcers were described.…”

“…Although there is no consensus in literature relative to the influence of sex on pododermatitis, Jacob et al (2015), observed a higher incidence in Cobb ® broilers compared with Ross ® broilers and in females relative to males. Santos et al (2002), in a study of pododermatitis in broilers, mentioned there is an initial inflammatory process associated with secondary proliferative response, which progresses to ulceration in the friction areas, with overlapping secondary bacterial infection.…”

“…Teixeira (2008) scored pododermatitis lesions in broilers' feet according an A to C scale, and also described the presence perivascular lymph nodes of various sizes and numbers in feet scored A, with a moderate inflammatory response in most cases. Santos et al (2002) studied footpad changes according to broiler age group, and reported discrete macroscopic changes characterized by Footpad Dermatitis in Broilers: Differences between Strains and Gender hydropic degeneration of the basal layer and stratum spinosum in 13-d-old broilers, whereas in 20-d-old birds, there were macroscopic cracks on the surface of the stratum corneum and epidermal hyperplasia associated with hydropic degeneration of the basal and stratum spinosum. In footpads with lesion score 3, overall epidermal strata structure and cell morphology were abnormal, and in some regions, it was no longer possible to identify the epidermal layers.…”

Pododermatitis, also known as "bumblefoot", is an inflammatory lesion of the footpad. The objective of this study was to evaluate the influence of genetic strain and sex on the incidence of footpad lesions in broilers. The experiment was carried out at São Paulo State University, using 480 broilers distributed in a completely randomized experimental design in a 2X2 factorial arrangement (2 strains X2 sexes), with four replicates of 30 broilers each, totaling 16 experimental units. Feed intake, weight gain, feed conversion ratio, and livability were evaluated at 21, 35 and 42 days of age; production efficiency factor was determined at the end of the rearing period. On day 42, the footpads of 100 broilers were grossly examined and assigned a lesion score in a 1-3 scale (Almeida Paz & Martins, 2014). Three samples per score within treatment were collected for microscopic evaluation. Analysis of variance was applied and performance parameter means were compared by Tukey's test. Footpad lesion incidence was analyzed by the χ2 test using SAS (version8.2). Ross ® broilers presented higher feed intake during all evaluated periods, and higher weight gain only in the period 1 to 21 days compared with Cobb ® broilers. On the other hand, Cobb ® presented better feed conversion ratio in the periods of 1 to 35 and 1 to 42 days. The incidence of foot pad lesions was statistically different (p<0.05) between strains and sexes, but there were no interactions between these factors. The lesion scores assigned were compatible with the histopathological results, showing that the higher the score, the more severe were the dermal and epidermal lesions.

“…High litter moisture may lead to cycles of wetting and drying that compact the material and causes burns and footpad dermatitis in broilers. This has been reported as economic problem for industrial broiler and turkey production in the United Kingdom, North America, Australia and Brazil (Santos et al, 2002).…”

“…Sorbara et al (2000),comparing citrus pulp with wood shavings as litter material for broilers, did not find any significant difference in the incidence of breast, tarsal-metatarsal joint and footpad lesions between treatments, concluding that litter material did not influence carcass quality. Santos et al (2002), in a study on the incidence of footpad lesions in broilers, concluded that the most probable cause of these lesions was excessive litter moisture. Another important and significant influence on carcass quality is flock density (Garcia et al, 2002).…”

The aim of this study was to evaluate the effects of different litter materials on litter compaction, broiler feathering and the incidence of carcass lesions. In the experiment, 3240 one-day-old Ross ® chicks were selected by sex and distributed according to a completely randomized experimental design in a 2 x 6 factorial arrangement (two sex and six litter materials). The following litter materials were used: wood shavings, rice husks, chopped Napier grass, 50% sugar cane bagasse plus 50% wood shavings, 50% sugar cane bagasse plus 50% rice husks, and pure sugar cane bagasse. Litter compaction was weekly assessed using a penetrometer. On days 21, 35 and 42 of the experimental period, feathering on the back and legs was scored according to a 0 -10 scale. On day 42, birds were slaughtered and the presence of bruises, scratches and footpad lesions was recorded. Litter material had no effect on bird feathering. Carcass lesions (scratches, bruises and footpad lesions) were influenced by the litter material evaluated. Birds reared on sugarcane bagasse and chopped Napier grass presented more scratches, bruises and footpad lesions than the others. Dermatitis was more evident in birds reared on sugarcane bagasse, chopped Napier grass and the combination of litter materials. It was found that males presented higher incidence of dermatitis and footpad lesions than females. Each litter material presented different compaction degrees, which increased along the experimental period. Sugarcane bagasse, chopped Napier grass and the combination of bedding materials presented the highest degree of compaction, compared with wood shavings and rice husks.

1. This study was conducted to verify the impact of different kinds of material and the number of times of litter reuse on the incidence of chicken pathologies. Approximately 4·5 million broilers from conventional Brazilian farms were evaluated in the abattoir for cellulitis, arthritis and contact foot-pad dermatitis. 2. Four different kinds of litter material, Brachiaria grass, corncob, sawdust and rice shell, were used. Brachiaria grass litter showed the highest incidence of contact foot-pad dermatitis. Corncob litter also showed some negative effects on foot quality. Broilers raised on rice shell litter showed good results in terms of the incidence of contact foot-pad dermatitis. The best results were obtained with sawdust litter, because the incidence of cellulitis and arthritis were the lowest and the incidence of contact foot-pad dermatitis was also very low.
