“…Rice husks have been studied and pointed as an appropriate alternative litter material (Bilgili et al, 2009;Chamblee & Yeatman, 2003). Rice husks are rapidly gaining space in the broiler litter market.…”

“…Although the birds had spent 19% of their time in the wood shavings and 13% in the rice husks, the activity of walking was greater on the rice husks. Several researches in assessing welfare were done for comparing broiler chicken behavioral expression reared on distinct bedding materials (Arnould et al, 2004;Chamblee & Yeatman, 2003;Shields et al, 2004;Shields et al, 2005;Stub & Vestergaard, 2001) and apparently their preference for expressing natural behavior such as stretching and preening is on sand bedding; however, their second choice appears to be soft wood shavings, followed by rice husks.…”

“…Several attempts of replacing the traditional litter material have been made, particularly to increase the sustainability of the poultry industry (Chamblee & Yeatman, 2003;Dias et al, 1987;Grimes et al, 2002;Grimes et al, 2007;Santos et al, 2000). Factors that influence the efficiency of a determined litter type are particle size, moisture content and buildup, caking rate, and other physical characteristics of the material (Hernandes et al, 2002;Oliveira & Carvalho, 2002;Toghyani et al, 2010).…”

Two experiments were carried out at the Poultry Sector of the School of Agrarian Sciences of the Federal University of Grande Dourados to evaluate the incidence of leg problems in broilers reared on two distinct types of bedding material: rice husks or wood shavings, both new and reused. In both trials, a randomized experimental design was applied in factorial arrangement (2 x 2 x 2) using two genetic strains (Cobb ® or Ross ® ); two sexes (male or female), and two litter materials (rice husks or wood shavings). In each trial 1080 one day pullets were reared equally divided in the treatments. The birds were placed in 4.5 m 2 boxes at a density of 10 birds m -2 . All birds were fed diets with equal nutritional density, and water was offered ad libitum. Feeds were divided in three phases: starter diet (1 -21 days), grower diet (22 -35 days), and finisher diet (36 -45 days). On day 45, fifty birds were randomly selected in each experiment to evaluate flock leg problems. The following parameters were analyzed: gait score, incidence of valgus and varus disorder, footpad dermatitis, femoral degeneration, tibial dyschondroplasia, and spondylolisthesis. Ambient temperature during rearing and litter caking and moisture content were recorded in four boxes per treatment. The analytical hierarchy process was used to organize the data into specific criteria. Several criteria, related to the attributes that were determinant according to the statistical analysis, were chosen in order to provide the best input to the process. Results indicated that new wood-shavings bedding was the most appropriate bedding to prevent locomotion problems, followed by new rice husks, reused wood shavings, and reused rice husks. However, when leg problems were associated to sex and genetic strain, male Ross birds strain presented less problems when reared on new rice husks, followed by new wood shavings

“…In poultry production, attempts have been made to use and test several types of material for litter: refined gypsum (Wyatt & Goodman, 1992;Grimes et al, 2006), recycled paper chips from waste newspapers (Lien et al, 1992), pelletized newspaper (Frame et al, 2002;Grimes et al, 2006), tree core-like kenaf core (Malone et al, 1990;Brake et al, 1993), particleboard residues (Hester et al, 1997), leaves (Willis et al, 1997), sand (Bilgili et al, 1999;Arnould et al, 2004), cotton waste (Grimes et al, 2006), hazelnut husks or wheat stalks (Sarica & Cam, 2000), wood shavings (Shields et al, 2005;Macklin et al, 2005), rice hulls (Swain & Sundaram, 2000;Shields et al, 2004), rice hull ashes (Chamblee et al, 2003), coffee husk (Ortiz et al, 2003;Ortiz et al, 2006), saw dust (Mendes et al, 2011), coir dust (Swain & Sundaram, 2000), straw (Al Homidan & Robertson,2003), feathers (Sanotra et al, 1995;Gunnarson et al, 2000), sugarcane bagasse or peat (Petherick & Duncan, 1989). The use of any of these substrates most often depends on the availability in each area and at each moment.…”

The aim of this study was to determine the selection of bedding material by broiler chickens during the rearing period and whether the choice was determinant to their performing a specific behavior. To achieve this objective, a choice test was designed. A choice pen was constructed where birds could move freely around the four selected materials (straw, wood shavings, rice hulls and sand). Chickens were introduced in this pen in four groups of eight birds, three days a week for one hour per day and group, for four weeks. The location and the activity performed by each broiler were recorded every five minutes. Results showed a preference for sand compared with the other three substrates. However, differences between the behaviors performed in each bedding material were shown mainly for resting (preferably performed on wood shavings and straw), dust bathing (on sand), pecking and scratching (on rice hulls). Other factors, such as the time of day, were also found to have effects on fighting and drinking, and changes in behavioral patterns (resting, preening, eating, standing and pecking) were also detected as broilers grew older.

“…Litter materials consist mainly of postharvest plant waste, wood industry residuals and various locally available products [1] . Common litter materials that have shown good results include wood shavings [2,3] ; rice hulls and ash [4][5][6][7] ; soft sawdust; corncob particles, fodder and stems of legumes and poaceae, sugarcane stems and peanut shells [8,9] ; exsiccated tree leaves [10] ; hazelnut husks [11,12] ; composted municipal garbage [13] ; recycled paper chips, shredded paper and pelleted newspaper [14][15][16] ; and inorganic soil products, pumice, clay, zeolite and sand [3,[17][18][19][20] . Other alternatives developed in recent years include pelleted industrial litter composed of various disinfected materials.…”

This study examined the effect of reusing litter on performance, viability and foot pad dermatitis (FPD) rates of three meat-type chicken genotypes with different growth rates and slaughter weights. Caking and manure accumulation of reused litter were also measured. A total of 780 chicks of 3 genotypes were raised in compartments (26 chickens per compartment, 11.55 chickens/m 2 ). Wood shavings were used as litter, with 5 compartments containing new litter and 5 containing re-used litter for each genotype. Differences in live weight, feed consumption, feed conversion ratio, viability and carcass parameters were significant among genotypes (P<0.05), but insignificant between new and used litter groups. FPD, caking and manure scores were higher on used litter. Overall findings suggest that with sufficient ventilation, litter can be reused, thereby decreasing costs of poultry production. 'de 11.55 piliç) deneme yürütülmüştür. Genotipler arasında canlı ağırlık, yem tüketimi, yemden yararlanma oranı ve yaşama gücü ile karkas özelliklerinde farklılıklar önemli bulunmuştur (P<0.05), buna karşılık yeni ve kullanılmış altlıkta yetiştirme bu özellikler üzerinde farklılık yaratmamıştır. FPD skorları, kekleşme skoru ve gübreleşme skorları ile altlık nem düzeyi kullanılmış altlıkta daha yüksek bulunmuştur. Elde edilen sonuçlar, yeterli havalandırma ile altlığın ikinci defa kullanmanın uygun olacağını ve altlık giderlerini azaltmada etkili olabileceğini önermiştir.
