This study was conducted to investigate the effects of capacitating agents added at in vitro fertilization (IVF) and antioxidants supplemented during in vitro culture (IVC) on the development of buffalo embryos. In experiment I, in vitro embryo development of buffalo embryos was compared when the IVF medium was supplemented with heparin, caffeine and calcium ionophore A23187 either alone or in ...

Follicle and oocyte growth is under the control of systemic gonadotropins and various local intraovarian factors. The present study was undertaken to examine the efficacy of peptide(s) isolated from ovine follicular fluid on preantral and antral follicles, oocytes, cumulus and granulosa cells, and oviductal epithelial cell growth in vitro in a heterologous species (Bubalus bubalis). Follicular ...

Production of high quality embryos in vitro needs an efficient in vitro fertilization (IVF). Seminal origin is one of the important factors that affects the success of in vitro embryo production. So our goal was to determine the effect of using fresh and frozen semen in fertilization on developmental competence and cryo-survival of buffalo embryos. Buffalo oocytes wer...

Buffalo holds the unique potentiality among the livestock sector at tropical and subtropical area. The faster multiplication of superior genotypes and the conservation of endangered buffalo breeds are the important issue. Recent advances in assisted reproductive technologies (ART), including estrus/ovulation synchronization, multiple ovulation and embryo transfer (MOET), in vitro embryo product...

The main goal of this study was to develop a comparative multi-colour Zoo-FISH on domestic ruminants metaphases using a combination of whole chromosome and sub-chromosomal painting probes obtained from the river buffalo species (Bubalus bubalis, 2n = 50,XY). A total of 13 DNA probes were obtained through chromosome microdissection and DOP-PCR amplification, labelled with two fluorochromes and s...

We report a simplified chemically-enhanced enucleation of in vitro matured buffalo oocytes for generating cytoplasts for producing nuclear transfer (NT) embryo production. Oocytes aspirated from the ovaries from abattoir were subjected to in vitro maturation for 22h. In the first experiment, the in vitro matured (IVM) oocytes (22h) were denuded and treated with demecolcine (0.50 μg/ml IVM mediu...

The evaluation of medium for in vitro maturation of buffalo oocytes has progressed towards more defined conditions for the studies evaluating effect of specific components in the medium. Therefore, aim of the present study was to evaluate the effect of fatty acid free-bovine serum albumin (FAF-BSA) alone or supplemented with epidermal growth factor (EGF) in the in vitro maturation medium on in ...
