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.x, 159 leavesBTDapplication/pdfIn CopyrightLD5655.V855 1985.S495Dairy cattle -- ExperimentsDairy cattle -- Feeding and feedsDairy cattle -- PhysiologyMilk yieldThesishttp://scholar.lib.vt.edu/theses/available/etd-03122013-040140/
