FERREIRA, H.A.; OLIVEIRA, M.C. y TRALDI, A.B.. Effect of chemical conditioners in the poultry litter on the broiler performance. Arq. Bras. Med. Vet. Zootec. [online]. 2004, vol.56, n.4, pp. 542-546. ISSN 0102-0935. http://dx.doi.org/10.1590/S0102-09352004000400017.
The effect of chemical conditioners in the poultry litter on the performance of broilers reared in three consecutive flocks was studied. One-thousand-three-hundred and twenty birds, 440 birds per each flock, were allotted to five treatments (Treat. 1 - untreated litter; Treat. 2 - litter treated with aluminum sulfate; Treat. 3 - litter treated with gypsum; Treat. 4 - litter treated with single superphosphate; and Treat. 5 - litter treated with hydrated lime) in a completely randomized block design and four replicates. Body weight, feed consumption, feed:gain ratio and viability were obtained. The conditioners did not affect (P>.05) body weight, feed consumption and feed:gain ratio. The aluminum sulfate and single superphosphate addition significantly reduced (P<.05) bird viabilities. Conditioners are not necessary for reused poultry litter until the third flock.
