“…() reported that the supplementation of a corn–soya bean diet with different enzyme preparations (with activity of galactosidase, xylanase, protease, amylase, glucanase or mannanase) had no effect on litter moisture as well as FPD incidence and severity. Similar results were observed when a mixture of NSP‐hydrolysing enzymes was added to the diet containing a high level of barley (Cengiz et al., ).…”

SummaryFoot pad dermatitis (FPD), a condition of inflammation and necrotic lesions on the plantar surface of the footpads, is commonly observed in fast-growing broiler chickens and turkeys. FPD negatively affects the welfare of birds, performance indices and the economic profit of poultry meat production. Nutrition is an important factor affecting water intake, excreta moisture and litter quality and, in this way, the occurrence and intensity of FPD in birds. This article reviews and discusses the recent results published in the literature on the effects of nutritional factors on litter quality and FPD severity in broiler chickens and turkeys. Literature data on the efficacy of nutritional methods on the litter quality and FPD occurrence are not consistent. However, the results of several experiments indicate that the optimal level of crude protein, biotin and electrolytes (Na, K) in the diet, as well as feed additives such as feed enzymes hydrolysating non-starch polysaccharides and organic sources of microelements (zinc), may reduce the litter moisture as well as FPD incidence and severity in broiler chickens and turkey.

“…Remarkably, litter pH showed a clear interaction between Glycan PB dose and xylanase inclusion in Trial 1. Xylanase inclusion has been reported to have negligible effects on litter pH in other studies, even when barley was included in the diet [24]. Cengiz et al [24] also reported no effects of xylanase on footpad lesions, even when the problem was exacerbated with increased litter moisture.…”

Cengiz et al [24] also reported no effects of xylanase on footpad lesions, even when the problem was exacerbated with increased litter moisture. Even though neither xylanase inclusion nor Glycan PB dose had effects on total N concentration in litter, there were interactions for both inorganic N and ammonia, which are highly correlated, as most of the inorganic N in litter is in the form of ammonia.…”

A dietary glycan-based precision biotic (Glycan PB) was evaluated on the performance, welfare indicators, and litter characteristics of broiler chickens. In Trial 1, the main effects of Glycan PB dose (0, 250 and 500 g/metric ton (MT)) and xylanase supplementation (0 or 100 g/MT) were tested, as was their interaction. In Trial 2, pens located inside a commercial house were used to test the effect of Glycan PB supplementation (500 g/MT) versus a control diet. In Trial 1, Glycan PB supplementation at 250 and 500 g/MT improved feed conversion ratio (FCR) by 7 and 11 points when compared to diets without Glycan PB (p < 0.001). At 35 d, Glycan PB reduced the pH and ammonia concentration in diets with xylanase. In Trial 1, the supplementation with 500 g of Glycan PB/MT of feed reduced litter scores (p < 0.05). In both trials, 500 g of Glycan PB/MT of feed increased the proportions of birds without footpad lesions (Trial 1: 72.2% vs. 82.7%; p < 0.001; Trial 2: 14 to 27.3% (p = 0.05) or gait defects (Trial 1: 96.1% vs. 98.4%; p < 0.001) and decreased the proportion of birds with footpad lesions (Trial 2: 86% vs. 72.7%; p = 0.05).

“…Several studies have reported a significant correlation between the type of feed provided (protein source, dietary enzyme and dietary sodium) and the quality of the litter and the resulting manure. This relationship determines the level of humidity, which in turn determines the concentrations of gases emitted [21][22][23]. In breeding projects, the stocking density is a factor characterized by a set of negatives and positives.…”

Air pollution in the environment in which poultry is raised is one of the most serious problems facing the poultry sector across various aspects of production. Perhaps the most dangerous gas emitted from poultry houses is ammonia. The high concentrations of this gas in the air above the permissible limits (15 ppm) will have disastrous consequences. Ammonia directly affects the health and safety of birds, as it is a cause of ammonia blindness in birds accompanied by many respiratory diseases that destroy production and increase breeding costs. In addition, high concentrations of ammonia (above 20 ppm) contribute to enhancing the infection of birds with Newcastle and the bronchitis virus. In general, the greenhouse gases emitted from poultry houses included four main gases (carbon dioxide, nitrous oxide, methane and hydrogen sulphide). Studies regarding their direct effects on the health and productivity of birds have been insufficient. In the direct form, as the concentrations of greenhouse gases rise to very high limits, they cause suffocation and death., the behaviour of the greenhouse gases in the indirect effect is reflected being a source of nutritional stress and a group of diseases and parasites which lead to a decrease in productivity levels. The intensity and concentrations of gas emissions are directly related to many factors such as geographic location, the season of the year, ventilation technologies, humidity, litter quality, nutritional status and stocking density. The advances in ventilation technologies have played a key role in expelling all harmful gases, especially those that depend on negative pressure. However, greenhouse gases remain a real threat to the poultry industry in particular and to the planet’s environment in general.
