Rectal-content metabolomic profiling of periparturient dairy cows supplemented with high-dose chromium propionate before calving

ABSTRACT: This study contains untargeted LC-MS/MS metabolomic profiles of rectal-content samples collected on the day of calving from Holstein dairy cows in the control and high-dose chromium propionate supplementation groups. Cows received either a basal total mixed ration without supplemental chromium propionate or the same ration supplemented with 20 g chromium propionate per cow per day, providing 8 mg Cr(III) per cow per day, from 21 days before expected calving until parturition. Rectal-content samples were collected aseptically at calving and analyzed to characterize hindgut metabolic responses associated with prepartum chromium propionate supplementation during the periparturient period.
