What is the process called when an arm is inserted into the rectum to assess pregnancy status in a cow?

• A. Palpation
• B. Ultrasound
• C. Auscultation
• D. Biopsy

Answer: (A)

Rectal palpation is the method used to determine pregnancy status in cattle by feeling the reproductive tract through the rectal wall. A trained person slides a lubricated, gloved hand into the rectum and uses touch to assess signs of pregnancy, such as an enlarged uterus, changes in the uterine horn, the presence of placentomes, or even a fetal membrane slip or fetus in later stages. This technique is valued because it’s quick, relatively inexpensive, and can provide useful information beyond pregnancy status, like fetal viability, empty or pregnant status, and gestational age cues, especially after about a month of gestation. Ultrasound, by contrast, relies on sound waves to image the fetus, and auscultation involves listening for fetal sounds rather than confirming pregnancy with tactile signs; biopsy is not a method used to determine pregnancy.
