The blood testosterone changes in three Giara stallions, average age 8 years old and average weight 183 Kgs, were checked weekly for a year using a radioimmunological method. The horses showed a highly seasonal hormonal activity concentrated in the first half of the year (winter and spring). In the second half of the year (summer and fall) the stallions showed low levels of testosterone. The highest level of the androgen hormone occurred in April, the lowest in October. The absolute levels of this hormone agreed substantially with the relative literature.
采用放射免疫法，对3匹贾拉种马（平均年龄8岁，平均体重183千克）的血液睾酮水平进行了为期一年的每周检查。这些马表现出高度的季节性激素活动，集中在一年的上半年（冬季和春季）。在下半年（夏季和秋季），种马的睾酮水平较低。雄激素的最高水平出现在4月，最低水平出现在10月。该激素的绝对水平与相关文献基本一致。
