Three groups of cross-bred bucks (Baladi X standard breeds) were exposed to solar radiation for three hours per day during an 8-week experimental period in June and July and were compared with a control subgroup of the same age. Each subgroup (experimental and control) comprised 10 bucks, totalling 60 bucks. The effects were determined and assessed during the 28-week period following the experiment. The exposure to solar radiation at 5 or 12 weeks of age caused a delay in the onset of puberty. In all three groups, the concentration of sperms and the fructose content were decreased. There was a marked increase in the proportion of abnormal or dead sperms and in the methylene blue reduction time. The young animals were most affected by the exposure.
在6月和7月为期8周的实验期内，将三组杂交雄鹿（巴拉迪×标准品种）每天暴露于太阳辐射下3小时，并与相同年龄的一个对照亚组进行比较。每个亚组（实验组和对照组）由10只雄鹿组成，总共60只雄鹿。在实验后的28周内确定并评估其影响。5周龄或12周龄时暴露于太阳辐射会导致青春期开始延迟。在所有三组中，精子浓度和果糖含量均降低。异常或死亡精子的比例以及亚甲蓝还原时间显著增加。幼龄动物受暴露影响最大。
