摘要

Microorganisms involved in the ensiling process include beneficial bacteria (homolactic acid bacteria), detrimental bacteria (for example, clostridia) and unwanted yeasts and moulds. In a good silage pit (or bun), air is eliminated by respiration fromthe plant and packing, thus preventing the growth of detrimental aerobic microbes. When air is eliminated from the silo, production of acid begins and a low pH eventually curtails the growth of all bacteria. A limited amount of heating during the earlydays of ensiling is good because it is an indication that bacteria are starting to ferment the silage. However, heating for prolonged periods oj time is an indication that there was too much air in the silage mass. Excessive heat can result in heat-damaged proteins, low energy values, and low dry matter recoveries. Preventing silage from spoiling can improve the efficiency oj a feedlot by preserving forage as high quality silage that is palatable to cattle.
