Young beef bulls are often fed high-energy diets to maximize postweaning growth; however, overnutrition has been associated with decreased semen quality. Seminal plasma has been shown to prime the uterus for early pregnancy events in mammalian species; thus, alterations in this response caused by overnutrition could be detrimental or beneficial. The present study evaluated the impact of seminal plasma from bulls exposed to overnutrition on the transcriptome of endometrial epithelial cells in vitro.

Article Synopsis
- The study assessed luteal color Doppler (CD) ultrasonography and blood levels of pregnancy-associated glycoproteins (PAG) for early pregnancy diagnosis in beef cows and their potential in predicting late embryonic/early fetal mortality (LEM).
- A total of 212 postpartum beef cows underwent a fixed-time artificial insemination, with evaluations including ultrasonography on specified days and blood samples for PAG measurement.
- The results showed high accuracy rates for both CD and PAG in detecting pregnancy, with no false negatives for CD, while decreased PAG levels were noted in cows that experienced LEM, indicating further research is needed to validate PAG as a predictor of pregnancy loss.
