“…These findings support those of other studies indicating a relationship between litter type and occurrence of contact dermatitis in broilers [6,48,49]. According to Boussaada and Ouachem [21], the type of litter affects the development of contact dermatitis (footpad, hock burn, and breast blister), with broilers reared on WS having lower dermatitis scores than those reared on other types of litter (straw, CR, and S). Sirri et al [29] also reported that flocks reared on WS showed less dermatitis than those reared on straw.…”

Background and Aim: In broiler production, the poor quality litter not only may lead to a deterioration of the welfare status but also negatively affect carcass quality, overall health and growth performance, which may result in economic losses. The effects of litter types on the welfare of broilers are known but the effects of their characteristics have been little studied. This study aimed to evaluate correlations between welfare parameters of broilers and physicochemical characteristics of five common litter types. Materials and Methods: Over 42 days, 600 (Cobb 700) male broiler chicks were placed within 30 pens (each 2 m2) at a density of 10 birds/m2. The experiment included five treatments with six replicates per treatment. The following litter (or bedding) materials were examined: Standard quality straw, low-quality straw, wood shavings (WS), sawdust, and crop residues. Footpad condition, hock burns, and plumage cleanliness, as well as litter condition, were scored according to previously developed point scale systems. Litter quality was evaluated according to pH level, moisture, water-holding capacity, and ammonia content. Results: No significant differences were found among litter types in terms of pH, moisture content, or ammonia levels. WS had a significant positive effect on footpad health and plumage cleanliness. However, hock burn was not affected by different bedding types. The severity of pododermatitis was negatively correlated with litter type (r = –0.78; p < 0.001) and positively correlated with the litter scores (r = 0.67; p < 0.001). However, contact dermatitis observed (pododermatitis and hock burn) was not correlated with any of the physicochemical parameters we studied. Meanwhile, we observed a correlation between footpad lesions and hock burn (r = 0.45; p < 0.05), and between footpad lesions and plumage cleanliness (r = 0.59; p < 0.01). Conclusion: For all litter types examined, contact dermatitis was not correlated with any of the physicochemical components we studied. There were, however, significant correlations between litter type and footpad lesions, as well as between footpad dermatitis and hock burns.

“…In our previous study, we found that the lesions of pododermatitis appeared from the first week of the broiler chicks reared on five litter types [21]. However, at this age, the different types of litter still seem dry and crumbly.…”

The prevalence and severity of pododermatitis can be used as indicators of the husbandry conditions and animal welfare that were present during the production cycle. The objective was to assess the frequency and extent of pododermatitis in broiler chickens in the wilaya of Batna and to study the risk factors associated with these lesions. This study focused on 30 broiler chicken flocks from different regions and slaughtered in two poultry slaughterhouses. Pododermatitis was measured in slaughterhouses according to the Welfare Quality® method (2009) on a sample of 100 chickens/flock. At the same time, a survey was conducted among poultry farmers to collect the necessary information on the farms concerned. The results showed very high variability in the distribution of the scores of pododermatitis according to the region of production. The results also revealed poor rearing conditions and a high prevalence of pododermatitis, which amounts to about 78%, ranged from mild skin inflammation (score 1) to severe ulcers (score 4), while 22% showed no lesion (score 0). In conclusion, in order to reduce the frequency of pododermatitis, it therefore seems necessary to control the breeding conditions, in particular the state of the moisture litter, the environmental parameters and the breeding density.
