Superovulatory response, embryo recovery and progesterone secretion in Boran (Bos indicus) cows after treatment with either Pergovet or Pluset

This study examines superovulatory response, embryo recovery rates, embryo quality, return to natural estrus, and patterns of progesterone secretion and its relationship with superovulatory response and embryo quality in Boran cows after treatment with either a human menopausal gonadotropin (Pergovet) or a porcine gonadotropin (Pluset) at 2 levels of doses each. Data presented show: treatment regimen for Boran cows superovulated with Pergovet or Pluset, least square means for number of corpora lutea, follicular cysts and embryos recovery rates in Boran cows after treatment with either Pergovet or Pluset, least square means for induced estrus duration, return to natural estrus, number of corpora lutea, follicular cysts and embryo recovery rates in Boran cows during three consecutive superovulations after treatment with either Pergovet or Pluset, and least square means for progesterone concentrations commencing on the first day of superovulatory treatment (Day 1) to the day of induced estrus (Day 5) in Boran cows which yielded different numbers of embryos/ova
