| Immediately after filling, silage gases may accumulate within the bag. If this occurs, bags should be vented with a knife to release gaseous pressure and then patched with the appropriate tape. During feedout, some manufacturers suggest that silage should be backbladed out of the bag before loading. This should help to reduce unnecessary pressure on the silage bags. |

| available carbohydrates (CHOs) are lost as heat and gas Emptying, which exposes surface, causing additional loss; rate of loss increases. Silage underneath plastic sheeting, held down by scrap tires. Concrete beneath the silage prevents liquor leaching out. Anaerobic digestion Anaerobic digesters Silage is a useful feedstock for anaerobic digestion. Here silage can be fed into anaerobic digesters to produce biogas that, in turn, can be used to generate electricity and heat. Safety Silos are hazardous, and deaths occur in the process of filling and maintaining them. There is a risk of injury by machinery or from falls. When a silo is filled, fine dust particles in the air can become explosive because of their large aggregate surface area. Also, fermentation presents respiratory hazards. The ensiling process produces "silo gas" during the early stages of the fermentation process. Silage gas contains nitric oxide (NO), which will react with oxygen (O2) in the air to form nitrogen dioxide (NO2), which is toxic. Lack of oxygen inside the silo can cause asphyxiation. |
