Won, Korean currency (1 USD was equal to ~1,100 Korean won at the time of study in 2012).
A unit cost: 597, 620 and 644 Korean won/kg, as-fed for the feed of growing, early fattening, and late fattening period, respectively.
A unit cost: 388 and 611 Korean won/kg as-fed for tall fescue straw and timothy hay, respectively.
A unit cost: 558, 558, and 575 Korean won/kg as-fed for feed of growing period, early fattening and late fattening period, respectively.
A, total feed cost; B, income, carcass; C, calf price.
Feed cost and calf purchasing cost were reflected with the cost during the whole experiment.
SCF, separate feeding of commercial concentrates and forage; TMRGSCF, feeding of TMR up to growing period and SCF from early up to the late fattening period; TMRGEFSCF, feeding of TMR from growing up to early fattening period and SCF up to the late fattening period; TMRW, feeding of TMR for the entire experimental period; TMR, total mixed ration.
