Answer to Question 1
A stallion is allowed to mount either a dummy or live mare and ejaculate into an artificial
vagina. The entire ejaculate is collected, measured, and examined in order to determine
fertility. A bull, on the other hand, is most often confined to a squeeze chute and ejaculated
through the use of an electrically charged probe. Only a small portion of the ejaculate is
collected and examined.
Answer to Question 2
By observing the animal prior to restraint, one may pick up on an existing lameness or gait
abnormality, and one may observe the mental status of the patient. These observations may
influence what restraint technique is used, diagnosis, and prognosis.
