WOS: 000457209100013Aerobic stability (silage life), and from the pop-up remains intact as a silage warming is defined as the length of time. Although oxygen input into silage is insignificant at fermentation stage or during fermentation this entrence is excessives during feeding. This case causes activation of yeast, mould, and aerobic microorganisms which leads to deterioration of silage. Consequently silage temperature and pH increases with lost of dry matter. As a result of these, increase in temperature, rise in pH, and loss of dry matter in silage occurs. Factors affecting the aerobic stability of silage can be grouped under four headings: (1) Physical, chemical and microbiological properties of silage material, (2) filling of silage material and silage density, (3) silage additives and fermentation, (4) feeding management. In this review factors affecting the aerobic stability of silage, and strategies for improving it were discussed
