Abstrakt		The accuracy of rectal palpation in the diagnostics of the ovarian function in cows has been controlled by transrectal ultrasonography and progesterone detection in milk. Compared to rectal palpation the sensitivity of both methods has been in follicular hase 95.5 per cent for ultrasound and 84.9 per cent for progesterone. The corresponding values for early luteal phase were 90.0 per cent and 87.8 per cent for diestrus 78.4 per cent and 77.4 per cent and for late luteal phase 83.8 per cent and 90.2 per cent, respectively. Corresponding positive values were: follicular phase 95.1 per cent and 82.7 per cent early luteal phase 55.3 per cent and 55.3 per cent , diestrus 86.7 per cent and 90.0 per cent and late luteal phase 22.9 per cent and 60.0 per cent, respectively. Concerning diestrus CL, ultrasonography was a more reliable method than rectal palpation, it si less reliable, however, concerning old CL because of small differences in ehogenicity. According to the above results the conclusion can be made, that the accuracy of rectal palpation was not ideal, but was quite useful to assure good results in diagnosing the condition of genitals and prediction of sexual cyclus phases in cows.
