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.
2BSs were collected from all cows within 8 h after calving and analyzed for FA profile as in Schubach et al. (2019).
