Upotreba oocita i embriona začuvanjeanimalnih genetskih resursaex situ (pregled)

Abstract: SažetakU poslednjih nekoliko dekada, genetski diverzitet domaćih životinja rapidno opada. S tim u vezi, postoji interes međunarodne zajednice za očuvanje genetike domaćih životinja. Model in situ čuvanja genoma je skup i značajno limitiran za praktičnu primenu. Zbog toga se razvija model ex situ (ex vivo) krioprezervacije animalnih genetskih rsursa (banke gena) za regeneraciju pojedinih poipulacija u budućnosti. Iako postoji značajan napredak u krioprezervaciji oocita i embriona pojedinih vrsta domaćih životin… Show more

“…Very high oestrus reaction (78 to 100% within 3 to 6 days after treatment), was achieved after treatment of gilts with 15 to 20mg Regumate (Altrenogest, synthetic analogue of progesterone) during 15 to 18 days Estiene et al, 2001;Horsley et al, 2005;Kaeoket, 2008). In one of our research (Stančić et al, 2009), within the first 7 days after treatment by Regumate, oestrus was estimated in 80% of gilts with prolonged preinsemination anoestrus (8 to 9 months of age) and in 53,3% of gilts 6 to 7 months of age. These results indicate that a significantly greater number of older gilts had established at least one spontaneous oestrus cycle, before starting of treatment.…”

“…In one of our research, at the Vojvodina farm units, it was found that 29,3% of gilts have been culled because of the prolonged preinsemination anoestrus , and that 45% of gilts were fertile inseminated when they are older than 8 months of age (Gagrčin et al, 2009). However, the post mortem examination of reproductive organs of such gilts, it was found that 50 to 70% of gilts, have functional ovarian structures (preovulatory follicles, corpora hemorrhagic, corpora lutea and corpora albicantia), which indicate that they have established cyclic pubertal ovarian activity (Einarsson et al, 1974;Stančić et al, 2005;Stančić et al, 2009). Moreover, 20 to 40% of the cyclic gilts were established two or three ovarian (oestrual) cycles before post mortem examination .…”
