1Nutrient analysis conducted by Analab (Fulton, IL). Values are reported as % DM. CON = control [a 24:20% CP:fat (as-fed basis) MR without EOC]; EP = EOC mixed into the 24:20% CP:fat MR at a rate of 1.25 g/d; EPC = EOC mixed into the 24:20% CP:fat MR at a rate of 1.25 g/d in addition of two 10-mL oral doses of liquid EOC at birth and 12 h. All MR were fed at 0.28 kg 2 times per day for 14 d, then 0.43 kg 2 times per day from days 15 to 35, and then MR were fed 1 time per day from day 36 to weaning at day 42. DM = dry matter; CP = crude protein; NDF = neutral detergent fiber; ADF = acid detergent fiber; ME = metabolizable energy.
2Metabolizeable energy, calculated according to the equations by National Research Council (2001).
