摘要: Contents Very little information is available regarding the physiological mechanisms involved in normal sexual activity stallion and, particular, the. endocrine control of reproduction still not clearly understood. This experiment was designed to determine short-term effect stimulation on plasma concentrations testosterone, cortisol, oestrone sulphate and 15-ketodihydro-PGF 2α stallions. Semen samples were collected from 10 lighthorse stallions proven fertility using a Missouri model artificial vagina. At same time, blood jugular vein with heparinized tubes, 20 min before oestrous mare exposure, at exposure 10, 20, 30 after dismounting. Testosterone showed sharp rise mating (p < 0.001), reached plateau, then further increase 0.001). Cortisol increased 0.001) remained high levels subsequent taken. A peak observed 15-Ketodihydro-PGF decreased rapidly moment an 0.05), returned pre-mating again 0.05).
