“…The final ranking of alternatives (Table 2) shows that the most appropriate broiler litter material under the studied scenario was wood shavings, followed by rice husks. 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.…”

“…The important factors that influence moisture in the rearing environment include short downtimes between flocks, partial-house brooding, evaporative cooling systems, and poor drinking water management (Bilgili et al, 2009). Health issues and the incidence of breast burns and blisters, leg abnormalities, and footpad lesions are reported in the literature as partially due to poor litter conditions (Benabdewelil & Ayach, 1996).…”

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.

RESUMO -Três experimentos foram conduzidos com o objetivo de avaliar o efeito da utilização de probióticos na dieta de frangos de corte sobre as características da cama reutilizada e das lesões de peito, joelho e coxim plantar. Foram utilizados em cada experimento 800 pintos machos de um dia, da linhagem comercial Ross, alojados em 20 boxes, em densidade populacional de 10 aves/m 2 . O delineamento foi inteiramente casualizado e os tratamentos distribuídos em esquema fatorial 2 × 2 (cama nova ou reutilizada × rações com ou sem probiótico). O probiótico utilizado nas dietas foi composto porBacillus subtilis e B. coagulans (2x10 9 e 1x10 7 ufc, respectivamente). Aos 42 dias de idade, quatro aves de cada boxe foram abatidas para análise das lesões de peito, joelho e coxim plantar. A cama de cada boxe foi amostrada para determinação dos teores de MS e nitrogênio, do potencial de volatilização de amônia e do pH. A cama reutilizada apresentou maior teor de MS, maiores valores de pH e potencial de volatilização de amônia e menor teor de nitrogênio. O probiótico usado nas rações resultou em maior potencial de volatilização de amônia. As lesões de coxim plantar e joelho foram maiores quando utilizada cama nova.As camas reutilizadas por dois, três e quatro ciclos causaram menores lesões de joelho e coxim plantar. O probiótico não promoveu efeito benéfico sobre a cama reutilizada.Palavras-chave: Bacillus, qualidade da cama de frango, pH, potencial de volatilização de amônia Evaluation of probiotics in diets for broilers raised on new or reused litterABSTRACT -Three experiments were conduced with the purpose of evaluating the effect of the addition of probiotics in the diet of broilers on the characteristics of reused litter and lesions of chest, knee and feet. Eight hundred male chicks, one day old, from Ross Commercial Breeding, were utilized in each experiment. The animals were housed in 20 pens in a populational density of 10 birds/m 2 . The experimental design was completely randomized and the treatments were organized in a 2 x 2 factorial arrangement (new or reused litter × diet with or without probiotic). The probiotic used in the feed was composed by Bacillus subtilis and B. coagulans (2x10 9 and 1x10 7 UFC respectively). When the animals were 42 days old, four birds from each box were slaughtered for determinations of DM and N contents and for measurements of potential for ammonia volatilization and pH. The reused litter presented higher DM content, pH value and potential for ammonia volatilization, and lower N content. The probiotic used in the diet promoted a higher ammonia volatilization potential.The feet lesions were bigger in broilers raised on new litter. It was concluded that litter reused for two, three and four cycles caused less knee and feet lesions and that the use of probiotic in the diet did not promote any beneficial effect on the reused poultry litter.Key Words: Bacillus, pH, poultry litter quality, potential for ammonia volatilization IntroduçãoEstima-se que a produção anual da cama proveniente da...

“…Litter moisture, pH, and ammonia emission were measured on days 1, 3, 5 and 8 of the experiment. The methodology of Benabdeljelil & Ayachi (1996) was adopted to measure the pH, using a digital pH meter model 330i/SET, WTW (Weilheim, Germany). Litter moisture was determined according to Carvalho et al (2011), and ammonia emission according to Hernandes & Cazetta (2001).…”

In broiler production, the litter is reused for consecutives flocks, and it is treated during down time between flocks to reduce its microbial load. Although covering the litter with a plastic canvas is a common litter treatment in the field, there is little scientific information available on its efficacy. The aim of this study was to evaluate the effects of covering broiler litter with a plastic canvas for eight days on litter microbiological, physical, and chemical parameters, and on the intestinal microbiota and immunity of broilers. In the first trial, reused litter from a previous flock was distributed into three treatments, with six replicates each: L1 (negative control, litter free from Salmonella Enteritidis (SE) and Eimeria maxima (EM) and not covered), L2 (positive control, litter with SE and EM, and not covered), and L3 (litter with SE and EM, and covered with plastic canvas for eight days). Litter total bacteria, Enterobacteria, Lactobacillus, SE, and EM counts, and litter pH, temperature, moisture, and ammonia emission were determined on days 1 and 8. In the second trial, broilers were housed on those litters according to the treatments described above, and their intestinal microbiota, gut CD4+ and CD8+ lymphocytes and macrophages, and liver and intestinal proinflammatory interleukin (IFN-γ, IL-1β e IL-18) levels were evaluated on days 14 and 28. A significant reduction of litter bacterial populations was observed in the litter covered with plastic canvas. A significantly higher mRNA IFN-γ gene expression (12.5-fold) was observed in the jejunum and liver of broilers reared on the litter with Enterobacteria counts. No EM reduction was observed in the covered litter. Covering reused broiler litter with plastic canvas reduces initial litter bacterial load as a result of the interaction between physical and chemical parameters.
