Potential prognostic markers of retained placenta in dairy cows identified by plasma metabolomics coupled with clinical laboratory indicators

Abstract: The complex etiopathology of retained placenta (RP) and hazards associated with it has made it crucial for researchers and clinical veterinarians to study pathogenesis, early-warning diagnosis, and treatment. This study aimed to screen the potential prognostic markers of RP in dairy cows using plasma metabolomics coupled with clinical laboratory indicators. Blood samples were collected from 260 dairy cows at 21, 14, 7, and 0 days before parturition and 7, 14, and 21 days after parturition. Consequently, 10 hea… Show more

“…Usually, the bovine placenta expelled 3-8 hours after parturition. Placental retention occurs if the fetal membranes fail to be released 12-24 hours after calf delivery (Li et al, 2022). Retained placenta can increase the risk of endometritis, metritis, and pyometra, which cause cow infertility (Li et al, 2022).…”

“…Untreated retained placenta can cause permanent infertility in dairy cows due to structural damage and functional disruption of the endometrial epithelium (Li et al, 2022). The endometrium produces PGF2α, which is crucial for the continuation of the estrus and reproductive cycles.…”

“…Good treatment of retained placenta is expected to restore reproductive function and milk production in dairy cows even though days open and calving intervals are extended. However, losses still occur from medical expenses, maintenance costs and lost opportunities to obtain milk from unproductive dairy cows, as well as lost opportunities to get one calf per cow in a year (Mahnani et al, 2021a;Li et al, 2022). Therefore, it is necessary to carry out corrective actions to evaluate some contributing factors in reducing the prevalence of retained placenta.…”

“…The maternal caruncle became smaller because the blood supply was reduced and the crypts in the caruncle widened. In a detached placenta, the detachment process is caused by chronic villous autolysis (Li et al, 2022). In retained placenta, the separation and detachment of the fetal placental villi (cotyledons) from the maternal placental crypts (caruncles) was disrupted and fusion occured, causing the placenta to not be expelled.…”
