AI Article Synopsis
- The study aimed to establish normal reference ranges for the combined thickness of the uterus and interplacentome region (CTUIR) in Holstein cows during pregnancy.
- CTUIR measurements were taken via transrectal ultrasonography every 30 days from 60 to 270 days of gestation, showing a steady increase in thickness over time.
- Results indicated that CTUIR averaged 4.6mm at 60 days and reached 11.7mm by 270 days, with the most significant increases occurring in the first and second trimesters.
Article Abstract
Combined thickness of the uterus and placenta (CTUP) has been used for many years to assess fetal well-being and placental health in the mare and most recently the combined thickness of the uterus and interplacentome region (CTUIR) in water buffalo. The aim of this study was to develop normal reference ranges in regards to the CTUIR in 25 Holstein cows throughout pregnancy. The CTUIR was measured every 30 days from 60 days of gestation until 270 days of gestation. Measurements were obtained by transrectal ultrasonography with the position of the ultrasound probe being placed cranial and lateral to the cervix. CTUIR measurements increased every month beginning with an average of 4.6mm at 60 days and culminating with an average thickness of 11.7mm at 270 days of gestation. The greatest increases in CTUIR thickness occurred during the first and second trimesters.
