Adding urea or limestone to forage sorghum silage increased lactic and
acetic acids compared with untreated silage. Urea also elevated the ensiling
temperature and increased the DM loss in the silo. Although calves fed the three
silages had similar performance, those fed the urea-treated silage tended to have
the highest consumption but poorest feed conversion. There were no apparent
improvements in silage conservation or feeding value from either urea or limestone.
