Summary Fertilisation and early embryonic development were studied in the following sequence: (1) detection of the pre-ovulatory follicle by daily ultrasonography; (2) induction of ovulation by injection of pituitary extract: (3) artificial inseminat

Nuclear maturation of equine oocytes was assessed immediately after in vivo collection. A double-staining technique (Hoechst and orcein) was used on the same oocytes to visualize nuclear morphology, i.e. to evaluate the chromatin configurations of ea

In mares, the shortage of oocytes and the variability in nuclear maturation at a certain time of the oestrous cycle hinders the optimization of methods for in vitro maturation and in vitro fertilization. Increasing the number of small-to-medium-sized

In the mare only a limited number of oocytes can be successfully collected in vivo, so that when large numbers of oocytes are needed for experimentation, ovaries harvested from slaughtered mares must be used. The resulting temperature changes and tim

The intrafollicular content of LH receptor, alpha-inhibin, and aromatase are known good indicators of follicular status. We investigated the amounts of these proteins in granulosa and cumulus cells in relation to oocyte competence for in vitro matura

This paper presents a method of measurement of the angular position of a traveling wave type ultrasonic motor (TWUM). This method uses the mechanical vibrations on the rotor to estimate its position. The working principle and the mathematical modelin

The objects of this study were to monitor the development of the cumulus complex and nuclear maturation in oocytes recovered from preovulatory follicles following treatment to induce ovulation and to investigate the in vitro maturation competence of

Equine oocyte competence after in vitro maturation (IVM) was investigated in terms of the diameter of the follicle of origin and the stage of the estrous cycle, with three criteria of maturation: nuclear stage after DNA Hoechst staining, meiotic spin
