Track 1-11: Advances in Forage Conservation to Improve Quality
Description
Silages arte widely used in animal production systems to overcome the seasonality of forage production around the world. The preservation of nutritional value of silages depends on the maintenance of an anaerobic environment during the fermentation and storage phases, as well from aerobic stability during the feed out stage (Nussio, 2005). Aerobic exposure usually promotes intense activity of fungi, yeast and aerobic bacteria. If the time of aerobic exposure is long enough, huge changes can happen in the chemical composition of the silages affecting negatively their nutritional value. These changes can be followed by decreasing lactic acid concentration and increasing pH, temperature and ammonia nitrogen (Addah et al. 2011).
The present work was carried out to evaluate the levels of ammonia nitrogen, pH, buffer capacity and electric conductivity in silages of Pioneiro grass and maize in different mixtures at silo opening and during the first 7 and 14 days of aerobic exposure.
