One of the application fields of nuclear transfer (NT) is to increase the population of endangered mammals. In the present study, cloning of native Anatolian Grey Cattle living semi-wildly especially in the Marmara Region was aimed. Bovine oocytes is

The objective of this study was to examine the effect of administration of FSH in aluminum hydroxide gel (Gel; an adjuvant and adsorbent of large molecules) by a single injection on superovulatory response and embryo recovery in cattle. In this study

Previous studies from our laboratory have demonstrated a positive association of follistatin mRNA abundance with oocyte competence. Follistatin mRNA is greater in germinal vesicle stage oocytes collected from prepubertal (model of poor oocyte compete

It is necessary to control the sex ratio (percentage of females) of pre-implantation embryos in the dairy industry. Several studies indicate that, in cattle, varying insemination time does not influence the embryo sex ratio (Rorie et al. 1999 Theriog

Despite many efforts to improve canine in vitro maturation (IVM), the efficiency is still low compared to that of other mammalian species (Marie et al. 2004). Epidermal growth factor (EGF) has stimulatory effects on the resumption of oocyte maturatio

Despite many attempts to improve the in vitro maturation (IVM) of canine oocytes using various culture conditions, the efficiency of canine IVM remains very low compared with that of other domestic animals. In the present study we examined the effect

In most mammals, maturation occurs within the ovarian follicle, and preovulatory oocytes are ovulated and ready for fertilization within the oviduct. In contrast, bitch ovulate primary oocytes, over a three day period, undergo both maturation and fer

A bitch ovulates a primary oocyte that undergoes both maturation and fertilization within the oviduct fluid for 3 days. In an attempt to define the physiologically appropriate conditions for oocyte maturation in the bitch, in vitro conditions based u

Two experiments were done to test the hypotheses that aging in cattle is associated with a reduction in the number of follicles recruited into an ovarian follicular wave, and a reduction in the ovarian response following gonadotropin treatment for su

Ultrasound-guided follicular puncture (OPU) has become the most used technique to recover cumulus-oocyte complexes (COCs) from valuable donors for in vitro embryo production, because of the low risk and the possibility of collecting COCs at intervals
