[討論]豬咬尾發(fā)生的前兆

中國(guó)西翁

2004年8月Asian Economic News報(bào)道：荷蘭科學(xué)家發(fā)現(xiàn)當(dāng)豬在應(yīng)激，煩躁?duì)顟B(tài)下，會(huì)伸直自己的尾巴。這種現(xiàn)象的出現(xiàn)標(biāo)志著不久豬群里將發(fā)生咬尾........
......豬發(fā)生咬尾的前2到3天，牠們伸直尾巴，并把尾巴藏于兩腿之間，這樣的狀態(tài)一直持續(xù)到咬尾的發(fā)生。研究者們觀察了1000頭沒(méi)有斷尾的豬。

我簡(jiǎn)單把原文意思介紹了一下，呵呵翻譯的不好多原諒。
原文如下：
Pigs straighten tails when bored, Dutch scientists say
Asian Economic News, August 23, 2004

Pigs straighten their tails when bored and stressed, Dutch scientists have detected.
This in turn can serve as a warning sign that within days they will start biting each other's tails, a habit that can cause serious injury and death.
Two to three days before pigs start biting each others' tails, they straighten their tail and hide it between their hind legs,'' Johan Zonderland, a researcher from Wageningen University in the Netherlands told Kyodo News. ''The animals stay like that for days until they start biting.''
Zonderland and his collaborators carried out their research over a period of three months. They carefully observed 1,000 pigs that still had their tails.
Most pig farmers cut off their pigs' tails to avoid the risk of tail-biting. Only biological farmers leave the animals as they are.
The research fits into a growing discussion about animal welfare. Animal rights groups say intensive agriculture creates psychological and physical health problems as too many pigs are gathered together in a small area.

It is the first time in the world that in-depth research has been carried out into the reasons behind "tail-biting,'' said Zonderland, whose country is one of the world's major exporters of pork products. These results will make it easier for farmers to detect problems in time. They can give the pigs some extra straw or toys to play with to prevent them hurting one another.''

另外，家畜生態(tài)2001，22（2）；14-21，崔衛(wèi)國(guó)，包軍所發(fā)表文章《異物特征和斷尾處理對(duì)斷奶仔豬啃咬行為及其生產(chǎn)性能的影響》中有如下論述：

在對(duì)發(fā)生咬尾的個(gè)體進(jìn)行觀察時(shí)發(fā)現(xiàn), 尾巴的空間位置似乎與咬尾有關(guān), 但需要進(jìn)一
步深入研究。M cGlone (1990) 發(fā)現(xiàn), 當(dāng)在特定環(huán)境下仔豬咬尾時(shí), 豬群中會(huì)有近1/3 的豬將尾巴下垂, 而在發(fā)生咬尾之前, 尾巴都表現(xiàn)為抬高或卷曲。尾巴的空間位置在豬群中有傳遞信息的作用, 尾巴下垂可以保護(hù)個(gè)體的尾巴不被咬到.

這個(gè)信息太重要啦,多謝

有機(jī)會(huì)驗(yàn)證一下

呵呵，誰(shuí)要是有機(jī)會(huì)驗(yàn)證了，一定要貼出來(lái)哦，謝謝！

以前還真沒(méi)聽(tīng)說(shuō)過(guò),謝謝了

意思是豬還是把尾巴剪掉比較好?~

看來(lái)不僅僅是人的心理和生理健康十分重要，動(dòng)物的也同樣重要，生產(chǎn)實(shí)踐中如何提高動(dòng)物生產(chǎn)性能的同時(shí)，保證其心理和生理健康呢？？這是所有畜牧工作者下一步要解決的問(wèn)題?。?！

小獸醫(yī)

沒(méi)人說(shuō)說(shuō)咬尾怎么辦嗎？？？？

這在豬群中怎么能觀察到
