The experimental treatments of grass silage, maize
silage, fermented WCW and urea-treated, processed
WCW, each supplemented with 3 kg concentrates/head/
day, are abbreviated GS, MS, FWCW and UPWCW,
respectively. The experimental treatment of ad libitum
concentrates supplemented with 5 kg grass silage/head/
day is abbreviated ALC.
3.1. Plant, silage and concentrate composition and
forage aerobic stability
The proportions of the wheat and maize plants made
up of grain and straw+chaff or stover at harvest time are
shown in Table 1. The wheat plant at both harvest times
contained approximately 0.5 grain and 0.5 straw+chaff.
The maize had a lower proportion of stover (compared
to straw+chaff) but a similar amount of grain as the
