The objective of the present study was to evaluate the effect of the hormone equine chorionic gonadotropin (eCG) on testosterone concentrations, sexual behavior and seminal quality in young Holstein gona- bulls. Twenty-one bulls of 12 ± 3 months of age and 350 ± 17 kg of live weight were selected. They were assigned to the following three treatments: T1 = 500 IU of eCG (n = 7); T2 = 1000 IU of eCG (n = 7) and T3 = Control (saline; n = 7). The administration of eCG was performed weekly during the period that the experiment lasted. There was an effect of the treatment ( p < 0.05) on the concentration of testosterone, being higher for the bulls that received 500 IU of eCG, followed by those that received 1000 IU of eCG. There was only a trend ( p = 0.09) of the effect of eCG on the number of mounts, being higher for bulls that received 500 IU (2.78 ± 0.35) and 1000 IU (3.29 ± 0.35) compared to the control group (2.23 ± 0.32). For the effect of the week of application of the eCG, an effect ( p < 0.05) was observed on each of the variables of sexual behavior, except for the reaction time to the first, second, and third mating. In conclusion, the application of eCG increased the concentration of testosterone, but without affecting sexual activity and seminal quality in young bulls during the winter season.
本研究的目的是评估激素马绒毛膜促性腺激素（eCG）对荷斯坦幼犬睾酮浓度、性行为和精液质量的影响。选择21头12±3个月大、活重350±17kg的公牛。他们被分配到以下三个处理：T1=500IU的eCG（n=7）；T2＝1000 IU的eCG（n＝7），T3＝对照（盐水；n＝7。在实验持续期间，每周进行eCG的给药。治疗对睾酮浓度有影响（p<0.05），接受500 IU eCG的公牛睾酮浓度更高，其次是接受1000 IU eCG的公牛。eCG对座头数量的影响只有一个趋势（p=0.09），与对照组（2.23±0.32）相比，接受500 IU（2.78±0.35）和1000 IU（3.29±0.35）的公牛更高。对于应用eCG的一周的影响，除了对第一、第二、，以及第三次交配。总之，eCG的应用增加了雄性激素的浓度，但不会影响冬季幼公牛的性活动和精液质量。
