Round bales of ryegrass and legume-grass silages were wrapped with stretch film. Initial bale moisture contents ranged from 25 to over 65% (wet basis). After six months in storage, apparent dry matter losses were not affected by initial moisture content. Significant changes were measured in crude protein, acid detergent fiber, and total digestible nutrients for all forages. However, changes in quality were not sigificantly affected by initial moisture content. Final moisture content of samples bored from 0 to 100 mm (0-4 in.) and 100 to 230 mm (4 to 9 in.) depths ranged from 14.0% to 71.7%. Moisture content had a significant on fermentation. Ryegrass silage samples above 50% moisture content averaged 2.5% of DM lactic acid and 0.5% of DM acetic acid while legume-grass silages averaged 1.0% of DM lactic acid and less than 0.4% of DM acetic acid. Of the 312 samples annalyzed, 17.9% had pH value above 6.5; a proportion that was relatively constant for samples having moisture contents less than 65%.
