Bioclimate of the Hall for Broiler-Chickens and Its Influence on Mycotic Contamination

Veterinarni Medicina 39, 1994, 329-336

Consequences between climate parameters of stable environment and mould occurrence were monitored during one fattening cycle. Xerophilic and hydrophilic species of moulds were diagnosed in the stable air. Their presence was especially influenced by contaminated feeding mixtures and litter. Mostly the ''storage'' species of moulds (Penicillium, Aspergillus) but also the ''field'' species (Fusarium, Alternaria) were isolated from the feeding mixtures. Xerophilic Penicillium species as well as hydrophylic species, e.g. Cladosporium dominated in litter in the beginning of the cycle. Yeasts dominated in the end of the cycle. In examinated samples of sedimented dust, the highest frequency of occurrence was in Penicillium germs
