If you have a new or novice stallion, we’ll start by training him to the phantom to facilitate semen collection and evaluation.

otherwise unavailable, or if you’re just preparing for the unthinkable, complete semen freezing services are also available.

latest diagnostic techniques, including a detailed ultrasound examination of the
reproductive tract and advanced laboratory testing.
