The sole formula (%) of the MB’s was: cane molasses, 40.0%; corn meal, 26.75%; ground limestone, 10.0%; salt, 10.0%; mineral supplement, 8.0%; urea, 5.0%; and sulfur, 0.25%. Following 12 d to accustom the animals to metabolism stalls, feces and urine were collected for 6 d. Daily dry matter (DM) intake from hay increased from 697 g in T1 to 700 g in T2 (P.05), while corresponding increases in totalDM(P
