豬“磨牙”的原因及防控技術(shù)

先行動(dòng)

這是一種早就被研究過(guò)的動(dòng)物固僻行為，是惡劣環(huán)境尤其是單調(diào)而應(yīng)激環(huán)境所致。懂英文的話查查文獻(xiàn)，能發(fā)現(xiàn)許多論述。

不要碰到什么老往營(yíng)養(yǎng)缺乏或感染性疾病上去想，那是無(wú)的放矢。野外自由活動(dòng)的動(dòng)物不管營(yíng)養(yǎng)多缺乏或感染性疾病的發(fā)病率多高，都很少見這種行為。所以改善環(huán)境是真正的預(yù)防手段。

中國(guó)農(nóng)業(yè)院校里有開動(dòng)物行為學(xué)課程的嗎？

先行動(dòng)

動(dòng)物固僻（重復(fù)而沒(méi)有功能）行為的起因：
How do stereotypies develop? One theory is that animals are motivated to perform a naturally occurring behaviour and if that behaviour is prevented or thwarted, it results in a chronic state of arousal. Once a critical level is reached, the animal performs an abnormal behaviour, such as a stable vice, in an attempt to decrease that arousal. Another theory is that most sequences of behaviour include two distinct phases: an appetitive phase, where the animal is motivated to perform a behaviour and a consummatory phase where the animal completes the behaviour to reduce the initial drive (ie. courtship is an appetitive behaviour terminated by mating). If the animal is unable to reach the second phase, it returns to the original sequence and begins again. Eventually the initial behavioural act becomes a fixed pattern which is refined until it barely resembles a normal behaviour.
