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...
