Abstract
In some aspects, disclosed herein is a method of determining pregnancy and identifying open cows, comprising breeding a cow, obtaining a genital tract sample from the cow, detecting a level of an interferon tau (IFNT) polypeptide in the genital tract sample; identifying the cow as pregnant if the level of IFNT is higher than a reference control or as not pregnant if the level of IFNT is the same as or lower than the reference control, and performing additional breeding of the cow if the cow is determined to be not pregnant.

- obtaining a genital tract sample from the cow;
- measuring a level of an interferon tau (IFNT) polypeptide in the genital tract sample;
