The objective of this study was to assess the effects of feeding negative dietary cation-anion difference (DCAD) dry cow diets on postpartum health. Cows from 4 commercial dairy farms in Ontario, Canada, were enrolled in a pen-level controlled trial from November 2017 to April 2019. Close-up pens (1 per farm), with cows 3 wk before expected calving, were randomly assigned to a negative DCAD [TRT; −108 mEq/kg of dry matter (DM); target urine pH 6.0–6.5] or a control diet (CON; +105 mEq/kg of DM with a placebo supplement).
