Abstract

A technique is described for recording butting activity in individually penned sheep as an index of aggression. The method used wall-mounted reflective sprung panels which, when depressed in response to a butt, activated totalising electronic counters automatically printing-out every hour. Eight Dalesbred wethers were tested using this system over a 5-week period. During the first week, the animals received no treatment and the panels were used sporadically. However, during Weeks 2–5, sheep (N = 4) treated with testosterone propionate (20 mg/day) increased their butting activity, whereas those (N = 4) similarly treated with dihydrotestosterone propionate did not. The results suggest that non-aromatizable androgens may not support aggression in the ram.

雄激素处理天气中对接活性的定量方法
描述了一种记录单独圈养的羊的碰撞活动作为侵略指数的技术。该方法使用安装在墙上的反射弹簧板,当按下该板以响应碰撞时,激活电子计数器,自动每小时打印一次。在为期5周的时间里,使用该系统对8名戴尔斯布莱德天气进行了测试。在第一周,动物没有接受任何治疗,并且偶尔使用面板。然而,在第2-5周期间,用丙酸睾酮(20 mg/天)处理的羊(N = 4)的抗顶活性增加,而用丙酸二氢睾酮处理的羊(N = 4)的抗顶活性没有增加。结果表明,非芳香化雄激素可能不支持公羊的攻击性。
