| Summary: | This study aimed to determine effects of postpartal relative body weight change (PRBWC) on production performance, serum biomarkers, and the relation between PRBWC and gastrointestinal microbiota. A total of 59 multiparous cows participated in this research. Every cow’s PRBWC was calculated by the following equation: PRBWC = (BW<sub>21</sub> − BW<sub>0</sub>)/BW<sub>0</sub> × 100%, in which BW<sub>21</sub> refers to body weight on Day 21 post-calving and BW<sub>0</sub> refers to body weight on the day of parturition. Among the 59 enrolled cows, cows with the top 21 ranked PRBWC values were categorized into the high PRBWC (H-PRBWC) group; cows with the bottom 21 ranked PRBWC values were categorized into the low PRBWC (L-PRBWC) group. PRBWC did not have significant influences on average daily milk yield (ADMY). However, on Day 21, cows in the H-PRBWC group displayed significantly higher body weight (BW) and body condition scores (BCS) (BW, <i>p</i> = 0.02; BCS, <i>p</i> < 0.01). Additionally, levels of serum glucose (GLU) and albumin (ALB) were significantly higher in the H-PRBWC group on Day 21 (GLU, <i>p</i> = 0.05; ALB, <i>p</i> < 0.01), while the lipopolysaccharide-binding protein (LBP) level was significant lower (<i>p</i> = 0.03). Moreover, the microbiota of fecal samples on Day 0 (FE0) differed notably between groups, as evidenced by various alpha diversity indices, including Shannon (<i>p</i> = 0.02), Simpson (<i>p</i> = 0.03), Pielou_e <i>(p</i> = 0.02), and principal coordinate analysis (<i>p</i> = 0.002). The relative abundances of <i>Monoglobus</i>, <i>norank_f__UCG-010</i>, and <i>Christensenellaceae_R-7_group</i> were significantly higher in the H-PRBWC group (<i>p</i> < 0.05), while the relative abundances of <i>Clostridium_sensu_stricto_1</i>, <i>Turicibacter</i>, and <i>Romboutsia</i> were significantly lower (<i>p</i> < 0.05). Pathways related to amino acid biosynthesis were significantly enriched in the FE0 of the H-PRBWC group, while pathways involved in carbohydrate metabolism were significantly upregulated in the FE0 of the L-PRBWC group. This study argues the potential of PRBWC to describe alteration of energy status in the postpartum, evidenced by production performance, serum biomarkers, and the fecal microbiota. |
