Abstract
Copulation was generally followed by increases in peripheral plasma 5α-androstenone and testosterone levels lasting for periods of about 60 to 100 min. The effect of copulation on the plasma levels of these steroids did, however, vary between boars. In seven out of eight boars the maximum levels of 5α-andro-stenone in the period 60 to 100 min. after copulation were from 114 to 218 % (mean 150 %) of the levels in samples collected before copulation. The corresponding figures for testosterone were from 104 to 283 % (mean 190 %). One boar showed decreasing plasma steroid levels after copulation. The coefficient of correlation between the peripheral plasma levels of 5α-androstenone and testosterone was found to be + 0.61 (n = 2.03).
摘要
交配后，外周血浆中5α - 雄烯酮和睾酮水平通常会升高，持续约60至100分钟。然而，交配对这些类固醇血浆水平的影响在公猪之间存在差异。在八头公猪中的七头中，交配后60至100分钟内5α - 雄烯酮的最高水平是交配前采集样本中水平的114%至218%（平均150%）。睾酮的相应数字为104%至283%（平均190%）。一头公猪在交配后血浆类固醇水平下降。发现外周血浆中5α - 雄烯酮和睾酮水平之间的相关系数为 + 0.61（n = 2.03）。
