The relationships between sexual and aggressive behaviors and levels of plasma testosterone and luteinizing hormone (LH) were examined in Hereford bulls at 18 and 24 mo of age. Concentrations of hormones in bulls during periods of sexual rest (13 blood samples collected from each animal during a 24-h period) were compared with individual differences in sexual and aggressive behaviors when exposed to restrained females, either individually or in groups. Nearly all correlation coefficients were low and nonsignificant. It was concluded that individual differences in sexual performance and aggressive behavior cannot be predicted based on circulating levels of testosterone and LH in bulls during periods of sexual rest.
研究了18月龄和24月龄的赫里福德公牛的性行为、攻击行为与血浆睾酮和促黄体生成素（LH）水平之间的关系。将公牛在性休止期（24小时内从每头动物采集13份血样）的激素浓度，与它们在单独或成群接触受约束的母牛时，性行为和攻击行为的个体差异进行了比较。几乎所有的相关系数都很低且无统计学意义。得出的结论是，不能根据公牛在性休止期循环的睾酮和LH水平来预测其性行为表现和攻击行为的个体差异。
