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 کاملIn Vitro Ovine Embryo Production: the Study of Seasonal and Oocyte Recovery Method Effects
BACKGROUND To current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (IVEP). OBJECTIVES The aim of this study was to define an efficient recovery method for oocytes harvesting from slaughterhouse material in different seasons, and their effects on IVEP yield. MATERIALS AND METHODS Ovaries from slaughtered ewes in breeding...

متن کاملImprovement in Bovine Embryo Production In Vitro
Bovine oocytes were matured, fertilized, and cultured FCM 199 with serum and co-culture) in vitro (IVMFC) with addition, during different phases of the procedure, of antioxidants: superoxide dismutase (SOD) and reduced glutathione (GSH). The addition of SOD (1,500 or 3,000 IU/ml) did not improve proportions of oocytes undergoing cleavage or the development of embryos to morula and blastocyst st...
متن کاملIn vitro embryo production in small ruminants
This paper reviews the technical bases of in vitro embryo production in small ruminants with special attention to the results obtained by our group in Northeastern Brazil. The laparoscopic oocyte recovery in hormonally treated live animals indicates a promising future for the application of this technique to genetic improvement program. New molecular biology tools should provide information to ...
