Abstract:
A total of 1050 samples of maize silage taken at various depths on premises for storing ensilaged feeds. The presence of eight species of microscopic fungi was demonstrated in the sampled silage: Mucor, Penicillium, Aspergillus, Alternaria, Trichoderma. It was established that highest was the number of species in the surface layer of the ensilaged mass. Considerably less were the species at a depth of 1.5 m, and then again the number of species rose toward the ground layer of silage. It is believed that lactic acid fermentation and the aerobic conditions exerted mycostatic effects. It was also demonstrated that with the aging of silage fungal species of the Fusarium and Trichoderma genera disappeared.
Insights
Microscopic fungi in maize silage varied by depth, with fewer species at 1.5m. Lactic acid fermentation and aerobic conditions inhibited fungal growth, and aging silage reduced Fusarium and Trichoderma species.
Area of Science:
- Agricultural Science
- Microbiology

Purpose:
- To investigate the distribution and diversity of microscopic fungi in maize silage at different storage depths.
- To identify fungal species present and their population dynamics.
- To explore the effects of silage aging and environmental conditions on fungal populations.
Summary:
- A study analyzed 1050 maize silage samples from various depths.
- Eight fungal species (Mucor, Penicillium, Aspergillus, Alternaria, Trichoderma, Fusarium) were identified.
- Fungal diversity was highest at the surface and ground layers, with a decrease at 1.5m depth.
- Lactic acid fermentation and aerobic conditions showed mycostatic effects.
- Fusarium and Trichoderma species were absent in aged silage.
Impact:
- Provides insights into fungal ecology within silage storage systems.
- Informs best practices for silage management to optimize feed quality.
- Highlights the role of fermentation and aeration in controlling fungal contamination.
