Collection of stallion semen without a mount.
Semen collection was attempted from 18 stallions with an artificial vagina (AV) and without use of a mare or dummy mount. After the stallions were sexually excited by the presence of another horse (mares, and in some instances, geldings) an AV was placed over the erect penis. Thirteen of the 18 stallions manifested thrusting and ejaculation in at least one attempt at semen collection. Semen was collected from 12 of the stallions on the first attempt with all subsequent attempts at semen collection from 11 of these 12 stallions being successful. The ejaculate from one of the stallions was judged incomplete based upon spermatozoal concentration compared with the concentration of a subsequent ejaculate obtained with a mount.
