Includes costs of collection/shipping, AV/phantom training, stallion training board, and shipped semen evaluation.
Equine Express type shippers typically used

To request shipment of semen from a stallion collected at TEVC:
2) Fill form using Adobe Acrobat Reader DC
Please note: Stallions do not stand on site; arrangements must be made with stallion owners to haul in stallions for collection. Additionally, clinic staff must be notified of requests for semen in advance, preferably 24 hours or more in advance.
Behavioral problem correction
Short-term boarding is offered for stallions in training. See above fee schedule.
Long-term boarding is not offered for stallions at Topline Equine Veterinary Care.
Breeding Soundness Examinations
- Pre-purchase exam
- Insurance purposes
- Determination of reproductive performance
- When a problem is suspected
- Annually to track any changes to a stallion's reproductive parameters and indicate any physical or behavioral problems.
- What does the exam entail?
-- General physical exam
- Body condition, conformation, soundness, and discussion of any heritable conditions which may affect breeding ability or desirability as a breeding stallion.
-- Reproductive and general health history
- Age, number of mares bred last year, previous method(s) of breeding, intended method of breeding, pregnancy rates, EVA status or vaccination, when the stallion was last bred or collected, any medications, current and recent health status (last 60-90 days) including illnesses or fevers.
-- Sexual behavior
- Willingness and ability of the stallion to mount and ejaculate. - Identifying and addressing issues with phantom or AV setup, as well as physical or sexual behavioral problems.
-- Examination of the reproductive genitalia
- The penis and sheath are inspected for any lesions, strictures, sores, trauma or swelling. Also ensuring the stallion's ability to obtain a rigid, straight erection, and that the penis can retract back into the sheath after ejaculation.
- The testes and epididymides are evaluated for size, shape, and consistency. Two testes should be descended into the scrotum. Testes are measured using a set of scrotal calipers to calculate the testicular volume.
-- Semen evaluation
- Daily sperm output (DSO) or how many sperm the stallion can ejaculate on a daily basis, can be determined by collecting two ejaculates an hour apart, after a stallion has been sexually rested for at least four days. The second ejaculate should provide approximately half the sperm. If this relationship does not occur, a variety of scenarios may have occurred. Alternatively, a stallion must be collected daily for 7-10 days or every other day for three weeks, and the last few ejaculates used to determine DSO.
- Volume, color, consistency, concentration (sperm counted by device, such as densimeter), total and progressive motility (determined by microscopic examination), and morphology (also determined by microscopic examination).
-Bacteriology in suspected cases of infection. Cultures can be taken from semen, urethra, urethral fossa, and sometimes the prepuce for bacterial isolation. Identification of pathogenic bacteria and a history of repeated infections in mares bred, may require breeding via AI using a semen extender which contains an appropriate antibiotic.
- Additional sperm testing for problems not easily discerned can be run at certain referral clinics or universities.
