Dry matter losses during hay production and storage of sweet sorghum used for methane production.

Losses from production and storage of large round hay bales from sweet sorghum were measured. Dry matter losses from hay production were 55.3%. Storage losses were 18.1% and 10.1% for outdoor and indoor storage, respectively. It was concluded hay storage of sweet sorghum used for anaerobic digestion is not a viable option.
