There is described a process for ensiling/conserving feed material which is pressed together, for example as a round ball. Liquid carbon dioxide is added to the pressed together feed material. The carbon dioxide is immediately converted to a carbon dioxide in the form of snow. When the carbon dioxide is in this phase the feed material is enclosed with a film-forming material, for example plastic. This ensures an anaerobic atmosphere, which gives a desired microbiological flora in the material. |
