The present study was undertaken to investigate the effects of ethylene glycol concentration and time of exposure to equilibration solution on the post-thaw morphological appearance and the in vitro maturation rate of buffalo oocytes. Vitrification solution-I (VS-I) consisted of 4.5M ethylene glycol (EG), 3.4M dimethyl sulphoxide, 5. 56mM glucose, 0.33mM(More)
The objective of the present study was to develop a method for the cryopreservation of buffalo oocytes by vitrification. Cumulus-oocyte complexes (COCs) were obtained from slaughterhouse ovaries. Prior to vitrification of COCs in the vitrification solution (VS) consisting of 4.5 M ethylene glycol, 3.4 M dimethyl sulfoxide, 5.56 mM glucose, 0.33 mM sodium(More)
The concept of ultra-rapid vitrification has emerged in recent years; the accelerated cooling rate reduced injury attributed to cryopreservation and improved post-freezing developmental competence of vitrified oocytes and embryos. The objectives of the present study were to develop a simple and effective ultra-rapid vitrification method (droplet(More)
The usefulness of IVF as a potential tool to evaluate the field fertility of bulls is equivocal and growth factor addition to culture media research is needed to delineate components needed for providing defined environments for embryos. The overall aim was to evaluate the in vitro development of embryos derived using a serum supplemented and serum-free(More)
The effect of modified droplet vitrification was assessed on cellular actin filament organization, apoptosis related gene expression and development competence in mouse embryos cultured in vitro. Mouse zygotes, 2-cell embryos and morulae were vitrified in ethylene glycol (VS-1) and ethylene glycol plus DMSO (VS-2) and thawed by directly placing the(More)
Antibiotic usage in animals as a growth promoter is considered as public health issue due to its negative impact on consumer health and environment. The present study aimed to evaluate effectiveness of herbal residue (ginger, Zingiber officinale, dried rhizome powder) and prebiotic (inulin) as an alternative to antibiotics by comparing fecal microflora(More)
