“…As suggested by Mayne et al (2007), straw may perform worse than materials like wood shavings due to its higher moisture content. This effect was also demonstrated by Terčič et al (2015), who found that straw litter had the highest moisture content (22%) compared with wood shavings (8%) and shredded paper (9%). It should be noted that the litter materials will vary between the regions depending on cost and availability.…”

“…We found that the flocks housed in barns that were bedded with straw had a higher prevalence of FPD compared with those that did not use a straw. In the literature, straw bedding is associated with more severe FPD than wood shavings Mayne et al, 2007;Terčič et al, 2015). As suggested by Mayne et al (2007), straw may perform worse than materials like wood shavings due to its higher moisture content.…”

A Cross-Sectional Study on the Prevalence of Footpad Dermatitis in Canadian Turkeys

Footpad dermatitis (FPD) can be a prevalent issue in commercial turkey production. This study aimed to identify the bird, housing, and management-related factors associated with the prevalence of FPD in the Canadian turkey flocks. A questionnaire and flock health scoring system were developed and disseminated to ~500 commercial turkey farmers across Canada. Farmers were asked to score FPD on a subset of 30 birds within their flock using a 0–2 scoring scale based on severity. The prevalence of FPD in the flock was calculated as the percentage of affected birds (score 1 or 2). A multivariate linear regression modeling was used to identify the factors associated with the prevalence of FPD. Four variables were included in the final model and accounted for 26.7% of the variation in FPD prevalence among the flocks. FPD prevalence was higher with increasing bird weight (3.6 ± 1.13), higher in flocks bedded with straw (12.1 ± 7.9), higher in flocks where birds were picked up less frequently during daily inspections (11.6 ± 8.10), and higher in flocks that used feed/water additives to reduce litter moisture (20.5 ± 10.59). These findings are a preliminary exploratory assessment of risk factors related to FPD prevalence on Canadian turkey farms. While these findings emphasize the importance of litter management and the stockperson, estimates and P-values from this study should be interpreted with caution. Further, longitudinal studies with the identified variables are required to better determine their influence on FPD.

“…However, the current groups did not differ (P >0.05) in the mean occurrence of HB (Figure 2), which could be because hock lesions develop more slowly and are less common than footpad lesions (EC, 2000). Other studies found no effect of litter type and quality (Haslam et al, 2006;Terčič et al, 2015) or stocking density (Haslam et al, 2007) on the occurrence of HB in broilers.…”

The aim of the study was to assess the effect of litter type and environmental enrichment on the occurrence of footpad dermatitis and hock burns in broilers housed at low and high stocking densities. Chopped straw and sand were used as litter, and perches as environmental enrichment. Low and high stocking density implied 12 chickens/m 2 and 20 chickens/m 2 , respectively. The study sample was divided into four groups of 50 birds, which were observed during a six-week fattening period. A significantly higher rate of severe footpad dermatitis was recorded in the group of chickens raised on sand at high stocking density, compared with low stocking density, whereas no significant difference was found between the groups of chickens raised on straw at different stocking densities. The rate of footpad dermatitis was also significantly higher in the group of chickens raised on sand at high stocking density, compared with chickens raised on straw at the same stocking density. There were no group differences in the occurrences of hock burns and perching. However, a significant negative correlation was recorded between perching and the occurrence of footpad dermatitis and hock burns. According to the occurrence of footpad dermatitis and hock burns, the study results suggested that chopped straw and sand were equally acceptable as litter for broilers, yet sand should be avoided at high stocking densities. There was no effect of stocking density and litter type on perching, but perches as a form of environmental enrichment proved efficient in reducing the rate of footpad dermatitis and hock burns.

“…Some studies using same methodology for fungal identification detected more mould genera, including Aspergillus sections, than we did ( 9 , 37 , 38 ), most likely because of different litter material. This suggests that straw litter, known to have higher moisture, pH, and temperature than other materials ( 44 , 52 , 53 , 54 ), favours the development of more homogeneous mycoflora.…”

This study aimed to compare fungal contamination of poultry litter between warm and cold seasons. It was carried out in commercial production conditions over two five-week fattening periods: one in the summer (July-August) and one in the winter (December-January). Broilers were reared on a litter composed of chopped straw and sawdust. Litter fungal concentration and composition were investigated weekly, along with litter temperature, moisture, and pH. Litter concentration of total fungi increased over both fattening periods, with no differences in median concentrations between them. Season also had no effect on yeast, Aspergillus section Nigri, and Cladosporium, Fusarium, and Rhizopus spp. concentrations, while the Aspergillus section Flavi and Aspergillus spp. combined showed higher concentrations in the summer, and Mucor and Penicillium spp. in the winter. Total fungal concentration highly correlated with litter temperature, moisture, and pH, regardless of the season. Our findings can be useful in the assessment and control of potential harmful effect of fungi on the health of poultry and poultry farm workers.
