A 9-year-old atactic breeding stallion was trained to ejaculate, with only manual stimulation, while standing on the ground. Ejaculates obtained yielded fertile semen with morphologic and motility characteristics within the range for normal stallions. This method extended the breeding life of a stallion unable to mount a live or dummy mare or to ejaculate into an artificial vagina while standing on the ground.
一匹9岁的共济失调种公马经过训练,仅通过人工刺激就能在站立于地面时射精。所采集的精液具有生育能力,其形态和活力特征在正常种公马的范围内。这种方法延长了一匹无法骑上活母马或假母马、也无法在站立于地面时向人工阴道射精的种公马的繁殖寿命。
