[The bioclimate in housing for broilers and its effect on mycotic contamination]

Abstract:
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 hydrophilic species, e.g. Cladosporium dominated in litter in the beginning of the cycle. Yeasts dominated in the end of the cycle. In examined samples of sedimented dust, the highest frequency of occurrence was in Penicillium germs.
Insights
Stable environments can harbor various mold species, influenced by contaminated feed and litter. Penicillium and Aspergillus were common storage molds, while Fusarium and Alternaria were field molds found in feed.
Area of Science:
- Mycology
- Environmental Science
- Animal Husbandry
Context:
- Livestock environments present unique challenges for air quality.
- Mold proliferation is a significant concern in animal husbandry settings.
- Understanding mold ecology in stables is crucial for animal health.
Purpose:
- To investigate the relationship between climate parameters and mold occurrence in a stable environment.
- To identify specific mold species present in stable air, feed, and litter.
- To determine factors influencing mold prevalence during an animal fattening cycle.
Summary:
- The study monitored mold occurrence in a stable, identifying both xerophilic and hydrophilic species.
- Contaminated feeding mixtures and litter were key factors influencing mold presence.
- Penicillium and Aspergillus (storage molds) and Fusarium and Alternaria (field molds) were isolated from feed, with Penicillium dominating in dust.
Impact:
- Findings highlight the impact of feed and litter quality on stable air mycobiota.
- Identifies Penicillium as a frequent contaminant in stable dust.
- Provides insights into mold dynamics within livestock environments, informing biosecurity measures.
