“…Also, the model presented here included age as a factor affecting excreta moisture level, indicating an age dependent effect on excreta moisture. However, the effect was contradictory to Eichner et al (2007), as in the present study increasing age reduced excreta moisture. The age data in our analysis may have been confounded by the effect of barn, where all samples collected at 17 d of age were collected from barn 2.…”

“…Additionally, differences in strain or age of the laying hens may have caused variability in the response. Indeed, an increased litter moisture with increasing broiler age was demonstrated by Eichner et al (2007) and was related to an increased water to feed ratio with age (Ziaei et al, 2008). Also, the model presented here included age as a factor affecting excreta moisture level, indicating an age dependent effect on excreta moisture.…”

High litter moisture content, often referred to as wet litter, is a major problem in poultry production. Wet litter is often related to poor management, diseases, and digestive problems. In this experiment, the objective was to study the relationship between nutrient content and the moisture content of the excreta of broilers. A dataset containing 351 observations was built and contained the nutrient contents data including moisture content of excreta samples collected in 8 different broiler feeding trials. A biological based model approach was used to create a model with 10 and another one with 14 variables that may explain the excreta moisture level response. Subsequently, these models were compared with a statistical model that was built automatically and adjusted only if this improved the biological model. The R 2 of the 10 variable model was 0.54, in which Zn content and the interaction of NDF × K and Ca × P content were negatively associated with excreta moisture. Sodium, P, and Ca content and the interaction between content of NDF × Na were positively associated with excreta moisture. The R 2 of the 14 variable model was 0.58, in which Zn and K content and the interaction of NDF × protein and Ca × P content were negatively associated with excreta moisture, and Na, protein, P, and Ca content and the interactions in contents of NDF × Na, NDF × Zn, and K × Cu were positively associated with excreta moisture content. In conclusion, the models confirmed the effect of Na, protein, P, and Ca on excreta moisture content. Furthermore, hitherto unknown nutrient interactions that contribute to excreta moisture level were identified. As excreta levels of most nutrients can be manipulated by adjusting dietary nutrient levels, dietary formulation can be adjusted with the findings of this analysis to change levels of excreted nutrients and, consequently, also moisture output.

“…On the other hand, Eichner et al (2007) and Nagaraj et al (2007) have found no significant correlation between litter moisture and the incidence and severity of FPD, which coincides with our results. In the fifth week of age, the application of Micropan led to the lowering of the pH with both types litter (chopped and unchopped).…”

“…Various litter amendments, such as chemicals -aluminium sulfate (Zhang et al, 2011), sodium bisulfate (Nagaraj et al, 2007;Li et al, 2012) -dietary manipulations (Ferguson et al, 1998;Eichner et al, 2007), zeolite (Li et al, 2008), microbiological preparation (Iwańczuk-Czernik et al, 2007), and a commercial ammonia binding agent (Lazarevic et al, 2014), are used to reduce litter moisture, pH, and NH 3 emission in boiler houses. Litter treatments with chemical or microbiological products have positive effects on litter condition by lowering the pH (Zhang et al, 2011), and reducing ammonia emission (Iwańczuk-Czernik et al, 2007;Li et al, 2008;Zhang et al, 2011) or litter moisture (Iwańczuk-Czernik et al, 2007;Lazarevic et al, 2014).…”

Abstract. This study was conducted to evaluate the impact of litter amendment (microbiological productMicropan complex) and straw size (unchopped and chopped straw) on pH, moisture level, ammonia emission, and footpad dermatitis in broilers. A total of 1200 1-day-old Ross 308 broilers were randomly allocated to four treatments (2 × 2 factorial arrangement), with four replicates per treatment. Each replicate consisted of 75 ashatched birds per pen. The first factor consisted of wheat straw -chopped (C) or unchopped (U ) -and the second factor was the litter amendment with (WM) or without (OM) Micropan ® (enzymatic bacterial productEurovix, USA). At 4, 5, and 6 weeks of the trial, the levels of ammonia concentration, moisture content, and pH of litter in each pen were measured. The foot pad lesions were evaluated at 21, 35, and 42 days of age. Broilers reared on chopped straw had significantly better leg condition as expressed by a smaller incidence and severity of footpad dermatitis. The pH value of litter was decreased and footpad quality was significantly improved by Micropan application in broilers kept on chopped and unchopped straw in the sixth week of age. There was no significant effect of Micropan application and straw size on ammonia emission in broiler housing.

“…When litter moisture exceeds 46% its surface becomes wet and friable and can cause footpad dermatitis and hock burns in broilers. Excreta adherence also causes prolonged contact with corrosive substances in the litter (Eichner et al, 2007). Thus, litter treatment with substances that reduce ammonia formation helps to improve broiler carcass quality along with lesion scores in breasts, hocks, and footpads (McWard and Taylor, 2000).…”

El tratamiento de la cama no afecta el desempeño ni las lesiones en la canal del pollo de engordeDesempenho produtivo e lesões na carcaça de frangos de corte não são afetados pelo tratamento da cama de frango SummaryBackground: broilers spend most of their lives in contact with litter; litter quality can affect their health and performance. Objective: the effects of litter treatment on performance and carcass lesions were evaluated in five consecutive flocks with 640 male broilers each. Methods: a completely randomized model was used comprising eight treatments and four replicates. The treatments included (1) untreated litter, (2) litter subjected to in-house composting, (3) litter treated (LT) with aluminum sulfate, (4) LT with gypsum, (5) LT with quicklime, (6) LT with dolomitic limestone, (7) LT with zeolite, and (8) LT with charcoal. Chopped elephant-grass hay was used as poultry litter in all flocks. Results: none of the litter treatments were found to influence the performance and carcass lesions of the male broilers in all five flocks. Furthermore, poultry litter treatments were not economically viable. Conclusion: poultry litter treatments did not affect the performance and scores of carcass lesions of male broilers, but increased the cost of poultry production.
