概括

在反向测试期间,肉的恐惧反应因鸟类的持方式而异. 抓住脚增加了翅膀的拍打和试图右相比,抓住腿部.

科学领域:

动物行为动物行为
鸟类福利鸟类福利
禽畜科学是一门学科.

背景情况:

评估家禽恐惧对于改善研究和福利至关重要.
逆转试验是一种标准化方法,用于测量家禽的恐惧.
处理技术可以影响恐惧反应的测量.

研究的目的:

为了研究两个不同的持有方法 (腿与脚) 在反转测试期间对 brojler 恐惧反应的影响.
为了确定持有技巧是否会影响特定的恐惧行为,如翅膀拍打,头部运动,正尝试和发声.

主要方法:

15岁和34岁的肉 (N=80) 接受了反转测试.
鸟类被抓住它们的腿或脚30秒.
从视频记录中量化了恐惧行为,包括翅膀拍打,头部运动,正尝试和发声.

主要成果:

抓住脚部显著增加了翅膀的动和试图在D15和D34上右转的尝试,而不是抓住腿部.
在D15.上,当鸟被子抓住时,头部的运动会更大.
声调在D15比D34更高,不管使用什么种养殖方法.

结论:

在反转试验期间使用的养家禽的方法显著影响观察到的恐惧行为.
处理技术的标准化对于在家禽研究中可靠和可重复的恐惧评估至关重要.
这些发现有助于完善评估鸟类福利的方法.

Types of Hypothesis Testing

Types of Hypothesis Testing

There are three types of hypothesis tests: right-tailed, left-tailed, and two-tailed.
When the null and alternative hypotheses are stated, it is observed that the null hypothesis is a neutral statement against which the alternative hypothesis is tested. The alternative hypothesis is a claim that instead has a certain direction. If the null hypothesis claims that p = 0.5, the alternative hypothesis would be an opposing statement to this and can be put either p > 0.5, p < 0.5, or p...
