Semen cryopreservation

Cryopreservation of semen increases the flexibility of a stallion that may be competing during a stud season, allows for international utilization of genetic material without transporting the stallion, and provides the opportunity to preserve semen from a stallion before gelding. Preservation at temperatures (-196°C/-320.8°F) where spermatozoa can be stored indefinitely.​ Used when a stallion is free from competition commitments and for storage of collected semen for an indefinite period to be used nationally, internationally or after the stallion's death (depending on stud book regulations).

Pinnal acanthosis

Pinnal acanthosis is a very common sometimes alarming complex skin lesion involving the skin of the inner surface of the pinna, caused by the papilloma virus. Signs include individual or coalescent pink or gray papules on the skin of the pinna. Can be extensive and much larger areas involved. A second form of the condition can be found on around the sheath and glabrous skin forward of umbilicus and more rarely still on the medial aspect of the thighs.
