“…Ammonia volatilization varied from 69 to 99 ppm in trial 2, and from 65 to 105 ppm in trial 3, with no difference (P > 0.05) among the bedding sources (data not shown). Tasistro et al [29] recently observed a significant interaction between bed-ding materials and sampling site on ammonia volatilization that was attributed to differences in moisture retention capacity. It was postulated that bedding materials with lower moisture retention would dry and form a crust faster, thus creating a physical barrier to ammonia volatilization.…”

Bedding availability issues are arising rapidly in the broiler industry that may alter the type and quality of bedding available to growers to rear broiler chickens. Because birds are in direct contact with the litter, the potential impact of bedding materials on footpad health is of concern. In 3 successive trials, 8 different bedding sources (pine shavings, pine bark, chipped pine, mortar sand, ground hardwood pallets, chopped straw, ground door filler, and cotton-gin trash) were compared in side-by-side experimental pens by rearing mixed-sex birds. In addition to broiler growth performance and litter characteristics (moisture, caking, and ammonia volatilization), the incidence and severity of footpad dermatitis (FPD) was assessed at 6 wk of age. Bedding materials had little influence on the live performance of broilers in 3 successive trials. Prevalence of FPD varied significantly (P < 0.05) among the bedding materials. The incidence of FPD paralleled high litter moisture and caking scores, with chipped pine, chopped straw, cotton-gin trash, and pine shavings showing the highest severity scores and mortar sand and ground door filler showing the lowest. From an FPD etiology standpoint, the ability of the bedding to absorb (i.e., ground door filler) and quickly release (i.e., mortar sand) moisture may be the most important characteristics.

“…It has been reported that wet litter conditions increase volatilization of ammonia from the litter (Nagaraj et al, 2007) and that ammonia emissions from wood shavings were 19% greater than from wheat straw around drinkers. In addition, worse caking was observed when wheat straw was used (Tasistro et al, 2007).…”

“…Most studies comparing poultry bedding materials have reported that, when birds are reared on alternative bedding materials, their performance is equal to or worse than that of birds reared on wood shavings (Benabdewelil & Ayach, 1996;Grimes et al, 2002). However, according to Tasistro et al (2007), broiler mortality was not affected when nonconventional bedding materials were used, although weight gain was significantly lower when birds were reared on wheat straw relative to wood shavings.…”

Alternative bedding material, broiler production, multiple criteria analysis, AHP. ABSTRACTBroiler chicken production is widely dispersed across the globe, and one important issue for growers is the selection of adequate bedding material, as the availability and price of substrates varies among countries and regions within a same country. This study aimed at applying a multiple criteria analysis approach for the selection of the most appropriate bedding material for broiler production. Based on field research data and growers' experience, the most desirable characteristics of a litter material were chosen as the main criteria. The selected materials were wood shavings, rice husks, chopped Napier grass (Pennisetum pupureum), 50% sugar cane bagasse (Saccharum L.) plus 50% wood shavings, 50% sugar cane bagasse (Saccharum L.) plus 50% rice husks, and pure sugar cane bagasse (Saccharum L.). The analytical hierarchy process (AHP) was applied for selecting the most suitable bedding material. Validation was performed using data from previous studies carried out in central-western Brazil on the effects of different types of bedding material on broiler carcass quality. Considering the selected criteria, several bedding materials were tested and ranked, and the results showed that wood-shavings litter was the best option (weight = 0.28), followed by rice husks (weight = 0.24). All other tested alternatives presented lower scores and were, therefore, not considered for use. The AHP approach was found to be an efficient tool to select the most appropriate litter material under specific scenarios.

“…However, almost no data are available under farm conditions in Europe, where litter is renewed between flock cycles. In addition, the quality and quantity of bedding materials can vary greatly from one region to another (Tasistro et al, 2007).…”

New alternatives are necessary if the environmental impact linked to intensive poultry production is to be reduced, and different litter handling methods should be explored. Among these, acidifying amendments added to poultry litters has been suggested as a management practice to help reduce the potential environmental effect involved in multiple flock cycles. There have been several studies on the use of aluminum sulfate (alum) and its benefits, but almost no data are available under farm conditions in Europe. An experiment with Ross 308 broilers from 1 to 42 days of age was conducted to evaluate the effect of alum on litter composition, the solubility of some mineral elements and NH3emission during a single flock-rearing period in commercial houses located in southeast Spain. Broilers were placed on clean wood shavings in four commercial houses, containing 20 000 broilers each. Before filling, alum was applied at a rate of 0.25 kg/m2to the wood shavings of two poultry houses, whereas the remaining two were used as control. Litter from each poultry house was sampled every 3 to 5 days. Ammonia emissions from the poultry houses were monitored from 37 to 42 days of age. In comparison with the control group, alum treatment significantly reduced the pH level of the litter (P< 0.001) with an average difference of 1.32 ± 0.24 units. Alum-treated litter showed, on average, a higher electrical conductivity than the control litter (5.52v.3.63 dS/m). The dry matter (DM) and total N and P contents did not show differences between the treatments (P> 0.05). Regarding the NH4+-N content, alum-treated litter showed a higher value than the untreated litter, with an average difference of 0.16 ± 0.07% (on a DM basis). On average, alum-treated litter had lower water-soluble P, Zn and Cu contents than the untreated litter. Alum noticeably reduced the in-house ammonia concentration (P< 0.001), with an average of 4.8 ppm at 42 days of age (62.9% lower than the control), and ammonia emissions from 37 to 42 days of age were significantly reduced by the alum treatment (P< 0.001), representing a reduction of 73.3%. The lower pH values might have reduced ammonia volatilization from the litter, with a corresponding positive effect on the building environment and poultry health. For these reasons, litter amendment with alum could be recommended as a way of reducing the pollution potential of European broiler facilities during a single flock cycle.
