Evaluation of a new avian bed conditioner used in the period between the creations of different batches of chicken

The present study had as objective to evaluate the effects of the use of the conditions lime virgin, agricultural gypsum and diatomaceous earth in the treatment of avian bed on the physicochemical, microbiological and toxicological aspects. The treatments consisted of: T1- Avian bed control (without treatment), T2- Avian bed + virgin lime (CaO) 600g/m², T3- Avian bed + gypsum agricultural (CaSO4) 600g/m² and T4- Avian bed + Earth diatomaceous 200 g/m². The germination index (%), mesophilic microorganisms, pH, carbon (%), nitrogen (%), C / N ratio, matter were evaluated for 15 days, simulating between lots of commercial aviaries. Dry matter (%), mineral matter (%) and organic matter (%), there was a similarity between the treatments, and the diatomaceous earth presented better results in the phytotoxicity tests, increasing the germination of the seeds significantly. In spite of this, more studies are necessary in order to obtain a conditioner that approaches the standard, that is, seeds germinated with distilled water, and at the same time they present improvement in the other analyzed parameters.
