In the first experiment the response of 93 adult stallions to stimulated and natural sexual stimuli was observed just before and 2 weeks after the breeding season (December and July respectively). About 72% of the stallions reacted the same before and after the breeding season (P less than 0.01) while 9% behaved similarly and 19% differently. Also, 72% of the stallions reacted with sexual arousal (mounting) to one of 3 successive simulated sexual stimuli; 25% to a dummy, an additional 44% to a gentle stallion and another 3% to a dummy smeared with mucus and urine from a mare in oestrus. In another experiment, the sexual behaviour of 4 young stallions and 3 older stallions was observed while they were in the stable. Erection was observed an average of 7.4 times in 24 h, a full erection 3.8 times and attempts to masturbate 4.1 times. Complete masturbation with ejaculation was only sporadically noted. The total time of erection averaged 38 min/24 h. The peak of erection time occurred in the morning and the low point during the night and at 05:00-08:00 h. No significant differences were found between the young and older stallions; differences occurred only between individual stallions.
在第一个实验中，观察了93匹成年种马在繁殖季节前（分别为12月）和繁殖季节后2周（7月）对刺激的和自然的性刺激的反应。约72%的种马在繁殖季节前后反应相同（P小于0.01），而9%表现相似，19%表现不同。此外，72%的种马对3个连续模拟性刺激之一有性唤起（爬跨）反应；25%对假马有反应，另有44%对温顺的种马有反应，还有3%对涂抹了发情母马黏液和尿液的假马有反应。在另一个实验中，观察了4匹年轻种马和3匹年长种马在厩中的性行为。24小时内平均观察到勃起7.4次，完全勃起3.8次，自慰尝试4.1次。仅偶尔观察到伴有射精的完全自慰。勃起总时间平均为38分钟/24小时。勃起时间的高峰出现在早晨，低谷出现在夜间以及05:00 - 08:00时。年轻种马和年长种马之间未发现显著差异；差异仅存在于个体种马之间。
