Abstract
In three types of domestic animals: cattle, pigs and sheep, morphology of ovary was studied. Results such as differences in shape, size within and between species, number of follicles in maturation, changes in sex cycle, connection of follicles in maturation are presented in figures. By method of aspiration, oocytes were isolated from ovaries and their cytology analyzed as the first step in methods of in vitro maturation (IVM), followed by in vitro fertilization (IVF) and embryo transfer. These methods are wide spread in modern livestock production (cattle, horses) since they have many advantages of which the most important is to obtain more offspring from high quality female heads. Method has disadvantage: potential diminishing of biodiversity, therefore special attention is necessary in order not to endanger biodiversity and still get more offspring with high production abilities and traits. IVM, IVF and embryo transfer represent new approach to selection, fast and with similar effec...t like in conventional artificial insemination, therefore they should be applied in practice also in our country.

Kod tri vrste domaćih životinja: goveda, svinja i ovaca, izučavana je morfologija jajnika. Rezultati: razlika u obliku, veličini inter i intraspecies, broj folikula u zrenju, promene tokom polnog ciklusa, povezanost folikula u zrenju; prikazani su na slikama. Iz jajnika su metodom aspiracije iz jajnika izolovane jajne ćelije i analizirana njihova citologija kao prvi korak u metodi in vitro sazrevanja (IVM), nakon koje slede in vitro oplodnja (IVF) i embriotransfer. Ove metode su široko rasprostranjene u modernom stočarstvu (goveda, konji) jer imaju niz prednosti od kojih je najvažnije dobijanje većeg broja potomaka od kvalitetnih ženskih grla. Metoda ima i nedostatak: moguće smanjenje biodiverziteta, i stoga treba voditi računa da se biodiverzitet ne ugrozi, a da se dobije veći broj potomstva sa visokim proizvodnim osobinama. IVM, IVF i embriotransfer su nov pristup selekciji, brzi, a sa sličnim efektom kao kod klasične veštačke selekcije, i zbog toga bi bilo dobro da nađu primenu i na... našim prostorima.
