1 st WorkshopXIII International Feed Technology Symposiumtreatment with the highest amount of lactic acid. From the same reason silages had thehigher amount of lipids compared with the starting material.The additives used had no significant influence on crude fiber content in silages,although there was a decreasing trend in treatments with urea. Some previousinvestigations suggest that ammonia may partially degrade lignocellulose complex,which was what probably happened in such treatments in this experiment [8].Table 2.
