Interpretive Summary:

Technical Abstract: Baled silage has increased substantially in popularity over the last quarter-century, and is especially popular among small and/or mid-sized forage and livestock producers. There are many reasons for this popularity, but the primary reasons include the ability to utilize much of the same equipment needed to conserve dry hay, as well as a reduced risk of rain damage to valuable forage crops. Most management principles for baled silages are similar to those often recommended for precision-chopped silages, but the fermentation of baled silages is inherently restricted compared to chopped silages. Fermentation is restricted by reduced moisture concentrations, less accessibility of sugars to bacteria responsible for fermentation, and generally less dry matter density within the silage. Specific research updates within this presentation include: i) moisture management - dry silages; ii) moisture management - wet silages; iii) effects of manure application on silage fermentation; iv) bale cutting/slicing mechanisms; v) effects of delayed wrapping; vi) fermentation in cold weather; and vii) aerobic stability. Baled silage techniques are applicable in many production situations, and this form of forage conservation will likely remain popular indefinitely.
