Fak., Diss., 2006 %X Aerobic deterioration in silages occurs after the penetration of air, for example when damage to silo covers occurs during ensilage or after opening the silo during the feedout phase of a well fermented silage. Thus, aerobic spoilage of silages represents a problem for animal feeding. Microbial metabolic activity leads to dry matter and energy losses in the silage. Dry matter losses of up to 3.5 % per day can occur in high DM silages (30 % DM) when the temperature is elevated by 15 ʿC above ambient (HONIG and WOOLFORD, 1980). A high proportion of DM losses can be explained by oxidation of fermentation acids (CRAWSHAW et al., 1980)... %L 630 %9 theses %9 Text %9 Hochschulschrift %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2007-0001-1 %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2007-0001-1&pdf %U http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2007-0001-1
