Forty-two high producing Holstein cows were paired by
body condition and mature equivalent milk production and fed
either a high or low energy complete ration ad libitum during
the last 16-20 weeks of lactation. Cows fed the high energy ration ate more feed, produced more milk and gained
more body condition than cows fed the low energy ration. Cows were fed to maintain condition during the dry period.
During weeks 3-15 of the next lactation, half the cows in
each condition group (fat or thin) were fed a mixed ration
with soybean meal (SBM) as the major protein source. The
remaining cows were fed a ration with dried brewers grains
(DBG) as the main protein source.
