[Non-surgical collection of uterine eggs in the rat (author's transl)].
The non-surgical collection of rat embryos were examined. The apparatus for uterine flushing (Fig. 1 and 2) were designed to have a two-way system. Egg collection were made 5 days after mating. Eggs were collected from anesthetized donors using a pair of glass pipettes inserted to the end of each uterine horn through the cervix uteri. By non-surgical technique, it was successful to collect the eggs at an average of 4.0 from all the animal. The recovery rate was 40.7% as estimated the number of corpora lutea counted after the slaughter of the donor. The recovery rat in non-surgical methods was considerably lower as compared with that of the uterine flushing after the slaughter.
