Subfertility Management

Each breeding season, there are a number of mares that come to ERC for specialty management. These mares typically have a history of abortion, early embryonic death or failure to conceive. A thorough diagnostic evaluation may initially be warranted in order to determine the possible cause(s) of subfertility. The best chances for a sustained pregnancy may only come when these mares undergo very detailed management practices. Routine ultrasound examinations are very important when assessing ovarian or uterine characteristics. Close attention is paid to follicle growth patterns, impending ovulation, uterine edema, cysts, fluid retention within the uterus and insemination frequency and volume. Management of these mares may include minimizing inseminations, performing uterine infusions and lavages, and administering hormonal treatment. The experience, technology and personnel at ERC has established a management program to help with the special needs of breeding operations.
