In vivo oocyte recovery and in vitro embryo production from bovine oocyte donors treated with progestagen, oestradiol and FSH.
The effect of treatment of donor cattle with progestagen and oestradiol or FSH on in vivo oocyte recovery and in vitro embryo production was studied. Forty-eight beefxFriesian cows formed eight replicates of six treatments in a 2 (no steroid versus steroid)x3 (none, single or multiple dose(s) of FSH) factorial design in which follicles were aspirated once weekly for 3 weeks. Oocytes were graded...
متن کاملInsulin exposure during in vitro bovine oocyte maturation changes blastocyst gene expression and developmental potential.
Metabolic imbalance impairs fertility, because changes in concentrations of metabolites and hormones in the blood and follicular fluid create an unfavourable environment for early embryonic development. Insulin is a key metabolic hormone known for its effects on fertility: insulin concentrations are increased during energy balance disturbances in diabetes or metabolic syndrome. Still, insulin i...
متن کاملEvaluation of frozen thawed cauda epididymal sperms and in vitro fertilizing potential of bovine sperm collected from the cauda epididymal
In the present study, the fertilizing potential of semen recovered from slaughtered bulls epididymis was evaluated after cryopreservation, by conventional techniques and flow cytometry methods. The cauda epididymal was dissected and sperm were recovered and evaluated for volume, sperm concentration, and membrane and acrosome integrity using a flow cytometer. Sperm fertility potential was tested...
متن کاملAbattoir survey of bovine pyelonephritis
In order to investigate the prevalence and detection of etiological agents of pyelonephritis in Shahrekordabattoir, 404 kidneys of slaughtered cattle (207 female and 197 male) were inspected. Kidney samples, whichhad gross changes were obtained for histological examination. Urine and renal tissue samples were alsocollected aseptically for microbiological examination. In histological examination...
متن کاملIn vitro production of bovine embryos: revisiting oocyte development and application of systems biology
In vitro production (IVP) of bovine embryos has become a widespread technology implemented in cattle breeding and production. The implementation of genomic selection and systems biology adds great dimensions to the impact of bovine IVP. The physical procedures included in the IVP process can still be improved, and aspects related to the oocyte donor, oocyte maturation and the recipients are add...
