“…In pen trials, used litter contaminated with S. Typhimurium did not cause transfer to newly placed chickens and the New Litter, N1 and N2 Salmonella in the litter could not be detected in 3-5 days (Olesiuk, Snoeyenbos, & Smyser, 1971). It has been shown that Salmonella does not persist as long in old poultry litter as in fresh litter (Fanelli, Sadler, & Brownell, 1970). In addition Salmonella levels in the caeca of chickens raised on used litter were significantly lower than those in chickens raised on new litter (Corrier, Hinton, Hargis, & DeLoach, 1992).…”

“…The capacity of used litter to shorten the carrier state of chickens and suppress Salmonella shedding and transmission was demonstrated more than 40 years ago [ 82 , 83 ]. This may explain why Salmonella infection rates can decline much more rapidly in chickens placed on bedding compared to those kept in cages [ 84 ].…”

Simple SummaryIn commercial chicken meat production, broiler chickens are usually kept on the floor in ware-house like buildings, but the use of cages is becoming more common. Confining chickens to cages is a welfare problem, as has been thoroughly demonstrated for laying hens used for egg production. Caged broiler chickens may suffer from poor bone strength due to lack of exercise, feather loss, and restriction of natural behavior. There are also potential food safety concerns associated with the use of cages. While cages may provide an economic advantage in some geographical regions of the world, the severe, inherent disadvantages should also be considered before cages are more widely adopted in the global broiler chicken industry.AbstractIn most areas of the world, broiler chickens are raised in floor systems, but cage confinement is becoming more common. The welfare of broiler chickens in cages is affected by movement restriction, poor bone strength due to lack of exercise, and prevention of key behavioral patterns such as dustbathing and ground scratching. Cages for broiler chickens also have a long history of causing skin and leg conditions that could further compromise welfare, but a lack of controlled studies makes it difficult to draw conclusions about newer cage designs. Cage environments are usually stocked at a higher density than open floor systems, and the limited studies available suggest that caging may lead to increased levels of fear and stress in the birds. Further, birds reared on the floor appear less likely to harbor and shed Salmonella, as litter may serve as a seeding agent for competitive exclusion by other microorganisms. Cages for laying hens used in egg production have met with substantial opposition due to welfare concerns and caging broiler chickens will likely be subject to the same kinds of social disapproval.

“…Contudo, quando ocorre algum problema sanitário, independentemente do número de lotes criados na mesma cama, é indispensável a retirada de todo o material para limpeza do galpão e higienização, estabelecendo-se vazio sanitário para o alojamento do próximo lote. Fanelli et al (1970), monitorando Salmonella infantis Salmonella Typhimurium, constataram que esses microrganismos tiveram menos persistência em cama reutilizada em comparação a cama nova. De acordo com esses autores, as camas reutilizadas parecem ter efeito inibitório que reduz a ocorrência da salmonela.…”

Avaliação de materiais alternativos em substituição à maravalha como cama de aviário

et al. 2008

RESUMO -Com o objetivo de testar materiais alternativos para cama de aviário na criação de frangos de corte, foram alojados seis lotes consecutivos, cada um contendo 5.600 aves, apenas fêmeas, distribuídas em 35 boxes. Os tratamentos consistiram de sete tipos de material para cama (maravalha; casca de arroz; sabugo de milho triturado; capim-cameron picado; palhada de soja picada; resto da cultura do milho picado; e serragem), cada um com cinco repetições. Avaliaram-se nas aves o peso corporal médio e o consumo médio de ração e, nas camas, os teores de N, Ca, P e pH. Observaram-se ainda a presença de salmonela, a contagem de oocistos de eimeria na cama e o escore de lesões no intestino das aves ao abate. A utilização dos materiais alternativos avaliados como cama de aviário, por seis lotes consecutivos, como alternativas à maravalha não prejudicou o desempenho de frangos de corte. Esses materiais, após o descarte, por apresentarem valor em minerais superior ao da maravalha, podem ser utilizados na adubação de culturas.Palavras-chave: consumo de ração, frangos de corte, peso corporal, reutilização de cama Alternative material to replace wood shavings as broiler litterABSTRACT -Aiming to evaluate alternative materials to be used as broiler litter reutilization, six consecutive lots of 5,600 female broilers were allocated to 35 pens. The treatments consisted of seven types of litter materials: wood shavings, rice husk, ground corncob, chopped camerongrass, chopped soybean straw, chopped corn stalk and sawdust, each one with five replications. In the birds, it was evaluated the average body weight, feed consumption and in the litter, it was evaluated the contents of N, Ca, P and pH. The presence of salmoella, the eimeria oocists counting in the litter, and the gut birds lesions score at slaughter were also observed. The use of alternative materials evaluated as litter, per six concecutive lots, as a alternative for wood shavings did no prejudice the performance of broilers. These materials, by presenting mineral values higher than wood shavings, after discarding, could be used as culture fertilizers.Key Words: body weight, broiler litter reutilization, feed consumption IntroduçãoA utilização da cama de aviário visa evitar o contato direto da ave com o piso, servir de substrato para absorção da água, incorporação de fezes, urina, penas, descamações da pele e restos de alimento caídos dos comedouros e contribuir para a redução das oscilações de temperatura no aviário (Avila et al., 1992).Com a expansão da avicultura e as melhorias da tecnologia de produção, o material utilizado como cama, em muitos casos, restringiu-se à maravalha, que foi se tornando progressivamente mais escassa e com maior valor de mercado; sua obtenção, em muitos casos, depende de fornecedores distantes, o que aumenta acentuadamente o custo. Alguns estudos têm sido conduzidos com o objetivo de propor materiais alternativos para preparação da cama. Assim, Oliveira et al. (1973) compararam diversos materiais (maravalha, bagaço de cana, sabugo picado...
