  • Breeding Management
    • The Hofmann Center offers breeding packages for mares being bred with fresh, chilled or frozen semen.  The packages include unlimited numbers of transrectal ultrasonographic examinations and artificial inseminations.  Board, medications and other treatments (ie. uterine lavage, uterine infusions) are additional. 

    • Mares managed for frozen semen breedings are carefully monitored throughout the daytime and evening hours and are bred via deep uterine horn insemination timed carefully to coincide with ovulation.  All mares, including those with foals, receive daily individual turnout in large outdoor paddocks and personalized care.

    • ICSI: Introcytoplasmic Sperm Injection
    • For mares that are not suited for embryo transfer, oocyte recovery and subsequent ICSI is another option that can result in pregnancies.  Oocyte aspiration and ICSI can be used for mares with chronic uterine infections, cervical problems, oviductal problems and other issues that prevent them from conceiving or carrying a pregnancy.
