ABSTRACT

ABSTRACT Primi- and multiparous Holstein cows (n = 162) at a commercial dairy herd were assigned to 1 of 4 treatments: control (no dose; n = 44); 200 mL of Lactipro (Megasphaera elsdenii, 1 × 108 cfu/mL; MSBiotec, Littleton, CO) when cows entered (~−14 DIM) the late gestation pen (n = 45); 200 mL of Lactipro at 1 to 3 d postpartum (n = 39); and dosed both prepartum and postpartum (n = 34). Late gestation cows were fed 72% forage (63:37 corn silage and wheat straw), and upon calving, cows entered the high-producing group and were fed 40% forage (90:10 corn silage:wheat straw). There were no differences (P > 0.10) in daily and peak milk yields among treatments. Compared with control and cows dosed both pre- and postpartum, cows with ≥3 lactations dosed prepartum produced 4.3 and 5.6 kg/d more milk, respectively, and 5.6 and 5.8 kg/d more (P
