“…The authors attributed this to the ingestion of acid litter because, according to Malone et al (1983), birds can consume up to 4% of their litter. However, a reduction in survival rate was not observed in this work.…”

El tratamiento de la cama no afecta el desempeño ni las lesiones en la canal del pollo de engordeDesempenho produtivo e lesões na carcaça de frangos de corte não são afetados pelo tratamento da cama de frango SummaryBackground: broilers spend most of their lives in contact with litter; litter quality can affect their health and performance. Objective: the effects of litter treatment on performance and carcass lesions were evaluated in five consecutive flocks with 640 male broilers each. Methods: a completely randomized model was used comprising eight treatments and four replicates. The treatments included (1) untreated litter, (2) litter subjected to in-house composting, (3) litter treated (LT) with aluminum sulfate, (4) LT with gypsum, (5) LT with quicklime, (6) LT with dolomitic limestone, (7) LT with zeolite, and (8) LT with charcoal. Chopped elephant-grass hay was used as poultry litter in all flocks. Results: none of the litter treatments were found to influence the performance and carcass lesions of the male broilers in all five flocks. Furthermore, poultry litter treatments were not economically viable. Conclusion: poultry litter treatments did not affect the performance and scores of carcass lesions of male broilers, but increased the cost of poultry production.

“…The type of litter material significantly influences broiler performance and carcass quality (Malone et al, 1983) and may stimulate specific behaviors in poultry. Toghyani et al (2010) showed that broilers reared on rice husks presented significant body weight, feed intake and antibody titer reduction (p < 0.05); however, no significant effect on the carcass yield and feed conversion was…”

The aim of this study was to evaluate the effects of different litter materials on litter compaction, broiler feathering and the incidence of carcass lesions. In the experiment, 3240 one-day-old Ross ® chicks were selected by sex and distributed according to a completely randomized experimental design in a 2 x 6 factorial arrangement (two sex and six litter materials). The following litter materials were used: wood shavings, rice husks, chopped Napier grass, 50% sugar cane bagasse plus 50% wood shavings, 50% sugar cane bagasse plus 50% rice husks, and pure sugar cane bagasse. Litter compaction was weekly assessed using a penetrometer. On days 21, 35 and 42 of the experimental period, feathering on the back and legs was scored according to a 0 -10 scale. On day 42, birds were slaughtered and the presence of bruises, scratches and footpad lesions was recorded. Litter material had no effect on bird feathering. Carcass lesions (scratches, bruises and footpad lesions) were influenced by the litter material evaluated. Birds reared on sugarcane bagasse and chopped Napier grass presented more scratches, bruises and footpad lesions than the others. Dermatitis was more evident in birds reared on sugarcane bagasse, chopped Napier grass and the combination of litter materials. It was found that males presented higher incidence of dermatitis and footpad lesions than females. Each litter material presented different compaction degrees, which increased along the experimental period. Sugarcane bagasse, chopped Napier grass and the combination of bedding materials presented the highest degree of compaction, compared with wood shavings and rice husks.

“…When data from Trials 2 and 3 were pooled, all PN treatments were significantly heavier than SD at all ages. As suggested by Malone et al (1983), SD litter consumption at an early age may contribute to part of these differences in body weight. Although broilers reared on fresh SD in Trial 1 had similar 49 day mortality to PN treatments, those placed on fresh SD in Trial 2 had more than twice the mortality over all other treatments (Table 2).…”

In three floor pen trials involving a total of 14,400 broilers, three particle sizes of processed newspaper (PN) were compared to sawdust as broiler litter. Litter treatments consisted of: hardwood sawdust (SD) as a control, a large particle processed newspaper (L-PN) ranging from 1.27 to 2.54 cm diameter, a medium size (M-PN) of .64 to 1.27 cm, and a small size (S-PN) with particles less than .64 cm diameter. The M-PN and S-PN were used both as a base layer and as a topping agent over a SD base in Trials 2 and 3.In all trials, broilers reared on the S-PN and M-PN used as a base or as a topping had numerically or statistically improved body weights over SD at 10, 28, and 49 days of age. In addition, the birds reared on SD had significantly higher mortality than all other treatments in Trial 2. Litter treatment had no significant effect on feed efficiency, litter cake, or total disease condemnations. The effect on conformation was not consistent between trials. The incidence of breast blisters was comparable to that of SD when the particle size of PN was reduced or when the PN was used as a topping. Broilers reared on PN had improved feathering, but the intensity of yellow color of the skin was reduced more than for broilers reared on SD.(Key words: processed newspaper litter, litter particle size, body weights, broilers)
