The prevention of poisoning in forage silos Abstract Forage ensiled in conventional tower silos undergoes fermentation that makes it more digestible and nourishing for livestock. This process generates toxic gases at concentrations likely to cause serious poisoning, and sometimes even death. Due to the oxygen deficiency and the presence of these gases, it is difficult to determine the moment when entry into a silo is safe. Ventilation remains the best means of ensuring the safety of these enclosed spaces during production work. The scientists will document the critical period in forage fermentation and toxic gas production. They will then formulate recommendations on the appropriate ventilation technique and on the parameters for using an efficient and practical ventilation system adapted to silos that will reduce the risks of poisoning related to the prevailing air quality.
