Research Project:
Identify Mechanisms by Which Ovulatory Follicle Size Affects Pregnancy Establishment and Maintenance in Beef Cows
Location: Miles City, Montana
Project Number: 5434-31000-016-08
Project Type:
Specific Cooperative Agreement
Start Date: May 01, 2008
End Date: Apr 20, 2010
Objective:
To improve our understanding of the mechanism(s) by which ovulatory follicle size affects pregnancy establishment and embryonic mortality.
Approach:
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 establishment & 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.
