Abstract :

Some studies represent that different factors play role in foot pad dermatitis but it seems the predisposing factor in this complication in wet litter that lead to maintain of this complication in poultry flock. This study was carried out in July to September of 2015, on 200000 broiler chickens (10 poultry flocks) that were suspected to foot pad dermatitis. Totally 200 samples (10 samples per 10000 chickens) were taken from foot pad lesions. The grading of lesions carried out based of severity of lesions. The mean of litter humidity and the mean of temperature in deep litter were 24.23 and 36.03 (respectively). The mean of foot pad dermatitis incidence in 10 flocks were 29.2%. In this experiment, in 200 bacterial cultures, the frequency of Staphylococcus, Streptococcus, Escherichia coli and coliforme infections were 60, 12.5, 16 and 11.5 percent (respectively). In this study, there was a significant relationship between humidity of litter and foot pad dermatitis (P<0.05).
