“…Taira et al (2014) reported that FPD started to occur in broilers in the second week of the fattening period. This was related to litter moisture, which is consistent with the study by Avdalovic et al (2017), in which the initial signs of FPD were observed in the third week. Kjaer et al (2006) noticed the initial signs of FPD and HB in the second week.…”

“…Nagaraj et al (2007) and Ramadan et al (2013) found that litter moisture had no effect on the occurrences of FPD and HB in broilers. However, other studies revealed that factors such as litter texture, season, lighting cycle, genotype and stocking density influenced the occurrence of contact dermatitis in broilers (Buijs et al, 2009;Shepherd & Fairchild, 2010;Škrbić et al, 2015;Farhadi et al, 2016;Avdalovic et al, 2017). The mean frequency of FPD was highest in broilers that were raised on sand at high stocking density, which differed (P <0.01) from the frequency recorded in broilers raised on sand at low density, and those raised on straw at high density (Figure 2).…”

“…The results can serve as recommendations for production conditions, although additional studies are suggested to investigate the mutual effects of various types of litter (Avdalovic et al, 2017;Kheravii et al, 2017), stocking densities and environmental enrichment (platforms, ramps, and outdoor access (ICFAW, 2009;Zhao et al, 2014;Norring et al, 2016;Kaukonen et al, 2017) on the occurrence of contact dermatitis and other health, behavioural and production indicators 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.

“…Not all of the trials that measured a given outcome were included in the NMA, because some intervention arms were collapsed into a single category which meant the trial was no longer comparative, and because some trials had zero cells which precluded the calculation of an OR. Of the 82 trials in which mortality was an outcome, 14 trials did not examine litter type, flooring type, or additives as an intervention (Supplementary Table S1), and four trials from three publications had zero cells for all intervention comparisons (Akpobome and Fanguy, 1992; Hafeez et al ., 2009; Avdalovic et al ., 2017). Additionally, the intervention arms were collapsed into the same intervention based on the treatment map for three of the trials (Do et al ., 2005; Abreu et al ., 2011; Mendes et al ., 2011).…”

A systematic review and network meta-analysis (NMA) were conducted to address the question, 'What is the efficacy of litter management strategies to reduce morbidity, mortality, condemnation at slaughter, or total antibiotic use in broilers?' Eligible studies were clinical trials published in English evaluating the efficacy of litter management in broilers on morbidity, condemnations at slaughter, mortality, or total antibiotic use. Multiple databases and two conference proceedings were searched for relevant literature. After relevance screening and data extraction, there were 50 trials evaluating litter type, 22 trials evaluating litter additives, 10 trials comparing fresh to re-used litter, and six trials evaluating floor type. NMAs were conducted for mortality (61 trials) and for the presence or absence of footpad lesions (15 trials). There were no differences in mortality among the litter types, floor types, or additives. For footpad lesions, peat moss appeared beneficial compared to straw, based on a small number of comparisons. In a pairwise meta-analysis, there was no association between fresh versus used litter on the risk of mortality, although there was considerable heterogeneity among studies (I 2 = 66%). There was poor reporting of key design features in many studies, and analyses rarely accounted for non-independence of observations within flocks. 248Jan M. Sargeant et al.

Effects of common litter types and their physicochemical properties on the welfare of broilers

et al. 2022

View full text Add to dashboard Cite

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.
