Research Project: Identify Mechanisms by Which Ovulatory Follicle Size Affects Pregnancy Establishment and Maintenance in Beef Cows

Location: Range and Livestock Research

Project Number: 3030-31000-017-17-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: May 1, 2013
End Date: Apr 30, 2018

To improve our understanding of the mechanism(s) by which ovulatory follicle size affects pregnancy establishment and embryonic mortality.

ARS – A student from Conapec will visit the Fort Keogh Livestock and Range Research Laboratory (LARRL) and evaluate the effects of serum estradiol and ovulatory follicle size on embryo quality & morphology, and pregnancy stablishment & maintenance in beef cows. Conapec – members will evaluate effects of exogenous estradiol cypionate, equine chorionic gonadotropin, and temporary calf removal on ovulatory follicle size, and establishment / maintenance of pregnancy in large beef herds in Brazil. Information will be mutually shared between involved parties.
