1Cows received (dry matter basis) 195 g/cow daily of CSSO (Essentiom; Church and Dwight Co., Inc., Princeton, NJ) or 170 g/cow daily of CON (Energy Booster 100; Milk Specialties, Eden Prairie, MN). Treatments were provided from day 0 (day 195 of gestation) to calving. Calves were weaned on day 290 of the experiment, preconditioned for 35 d (day 291 to 325), and transferred to a feedyard (Cannon Hill Feeders LLC., Nyssa, OR) where they remained until slaughter (day 514).
2Samples of the LM were taken via needle biopsy within 8 h after birth and on day 485 of the experiment. Values are expressed as relative fold change compared with the threshold cycle of reference genes analyzed within the same sample (Ocón-Grove et al., 2008).
