Semen is often collected from stallions using an estrous or ovariectomized teaser mare. The disadvantages of this practice are that it can be dangerous for the collection team, the mare and the stallion, and there is a good possibility that sometimes the mare will be bred by the stallion. To protect the stallion, the mare should be hobbled to prevent kicking. An alternative to use teaser mare is to use a "phantom" mount - an inanimate mare look-a-like. Roughly 2 of 3 stallions can be trained to mount and be collected using a phantom. This method is outlined below.
