Abstract
Since the number of days between calving and subsequent conception determines the calving interval in cattle, early pregnancy diagnosis has become a key to economic succes. Pregnancy is generally diagnosed by palpating the uterus and its contents per rectum. The accuracy of this method and the earliest time of which pregnancy can be recognized is dependent upon the experience of the palpator and on the pregnancy diagnosis criteria used.
