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.
