Question

You perform a progesterone test on a cow at 21 days post-breeding. The result is 1ng progesterone. What is the correct interpretation?

Answer 1

A progesterone test result of 1ng in a cow at 21 days post-breeding indicates that the cow is not pregnant.

Step-by-step explanation:

The correct interpretation of a progesterone test result of 1ng in a cow at 21 days post-breeding is that the cow is not pregnant. As stated in the reference information, if no pregnancy occurs within approximately 10 to 12 days, the corpus luteum, which produces progesterone, will degrade and progesterone levels will fall. In this case, the low level of progesterone indicates that the cow is not pregnant.
