Progesterone, a natural hormone that circulates in the cow's blood and is also found in the milk, is produced by the corpus luteum (CL) after ovulation and fluctuates during a normal estrous cycle. Progesterone levels accurately reflect the different stages of the estrous cycle.
Testing progesterone about 20 days after insemination can identify open cows
by a bright blue result
. The open cows can then be rebred. If progesterone levels are high, the cow is pregnant.
Identifying open cows earlier will reduce the days open and lower costs.

...FOR EMBRYO TRANSFERS
Because every embryo is valuable and the successful
and nurturing of the embryo depends on the amount of progesterone present, testing of the recipient is an integral step in an embryo transfer protocol.
TARGET Bovine CL Chek progesterone tests are the dependable, easy to use kits that veterinarians trust. TARGET has been demonstrated to be greater than 97% accurate in a study done at Ohio State University, College of Veterinary Medicine.
"TARGET is a very accurate and valuable test, and I recommend it for checking all embryo transfer recipients."…
