Residual feed intake in peripartal dairy cows is associated with differences in milk fat yield, ruminal bacteria, biopolymer hydrolyzing enzymes, and circulating biomarkers of immunometabolism

Ingredient composition of TMR diets fed during close-up (-28 d to calving) and fresh (from 1 to 28 DIM) periods in the 5 different published studies used for residual feed intake (RFI) evaluation. Supplemental Table S2. Nutrient composition and energy density (NRC, 2001) of TMR diets fed during close-up (-28 d to calving) and fresh (from 1 to 28 DIM) periods in the 5 different published studies used for residual feed intake (RFI) evaluation. Supplemental Table S3. Species-specific primers for the quantification of 17 key ruminal bacteria by quantitative RT-PCR assay in least-efficient and most-efficient multiparous Holstein dairy cows during prepartal and early lactation periods. Supplemental Table S4. Milk yield and composition in least-efficient (L-eff) and most-efficient (M-eff) multiparous Holstein dairy cows during the first 30 d of lactation in the subset used for blood plasma biomarker analyses. Supplemental Table S5. Milk yield and composition in least-efficient (L-eff) and most-efficient (M-eff) multiparous Holstein dairy cows during the first 30 d of lactation in the subset used for ruminal digesta sampling for measuring biopolymer degrading enzyme activities.
