| Abstract: | Between January 1993 and April 1998 in a total of 27,378 sheep an ultrasonographic early pregnancy diagnosis was done. The determined pregnancy rates (mean = 82.2%) were related to the mating systems, duration of mating season and time of the year. The benefits of scanning are described. If the pregnancy rate is lower than 97% the early pregnancy diagnosis is economical to flock management. Cases of uterine and fetal pathology (fetal mortality, maceration, hydrometra, pyometra) are presented. |
