[討論]豬咬尾發(fā)生的前兆

中國西翁

2004年8月Asian Economic News報道：荷蘭科學家發(fā)現(xiàn)當豬在應激，煩躁狀態(tài)下，會伸直自己的尾巴。這種現(xiàn)象的出現(xiàn)標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頭沒有斷尾的豬。

我簡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，包軍所發(fā)表文章《異物特征和斷尾處理對斷奶仔豬啃咬行為及其生產(chǎn)性能的影響》中有如下論述：

在對發(fā)生咬尾的個體進行觀察時發(fā)現(xiàn), 尾巴的空間位置似乎與咬尾有關, 但需要進一
步深入研究。M cGlone (1990) 發(fā)現(xiàn), 當在特定環(huán)境下仔豬咬尾時, 豬群中會有近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, 尾巴下垂可以保護個體的尾巴不被咬到.

沒有解決辦法？需要專業(yè)人士的解答，以及實踐論證??！

請大家驗證一下，方法，把一欄豬的海會穴處涂一點酒精可辣椒，豬豬尾就會抬起了，注意觀察哈，結果會如何！

豬無敵

這個說法不準確 真的不準確 ， 我這本地豬沒剪尾沒剪牙， 上面說的也只是觀察了1000多頭而已。。 我都觀察過不下500頭 ； 這個說法的命中率很低

基本上夾起尾巴的都會引起注意 ， 更多的是發(fā)燒拉稀，發(fā)生咬尾一例都沒見到。

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

豬豬身體不舒服的時候也有這樣的現(xiàn)象啊，不一定就是咬尾的前兆吧！

不知讓豬聽音樂會不會安靜下來，淺蘭色的環(huán)境能使人心情平靜，把豬舍刷成淺蘭色會不會有作用。因為關鍵是豬煩燥不安引起的。

又跟樓主學習了一招，有機會觀察一下

學到很多，謝謝樓主

值得研究，以后仔細看看，是不是這么回事
