咬尾巴

四林繁

請問各位前輩，各位先進豬場內咬尾巴的比率高嘛，還有造成的原因是何原因呢？
把咬尾巴的豬隻調離，不久後又發現了，書上說缺乏某種營養素也會造成，驗飼料營養也沒問題，
看來只剩下飼養管理了，真不知何處出問題，只好請各位指點迷津了。
謝謝

請問豬欄中有沒有放一些東西讓豬去把玩呢???
(例如廢輪胎之類的...)
豬只要醒著就會咬東咬西, 如果沒有飼料,沒有"玩具",只好以欺負同伴為樂

或者是尾部有出血的情形, 血腥味會引起獸性, 咬得更激烈喔~

不過, 飼養管理真的需要飼主仔細觀察才能找出問題,我們這樣講也不一定有幫助...   加油!!!

如果沒記錯應該是鹽分跟電解質要注意~

避免方式除了隔開就是噴灑消毒水~

讓豬豬聞不到血腥味而咬食~

最近玉米品質粉差~
應該是黴菌毒素在作怪ㄅ...

慎選添加劑...增加蛋胺酸&維他命ㄉ量...
病豬移出...打消炎針...患部勤擦碘酒約莫一週即可痊癒...

Solving Tail-Biting Problems
From Pork Information Gateway. Todd See gives an overview of the environmental, management and nutritional causes of tail-biting.


Outbreaks of tail-biting occur in intensive pork production when a pig bites or chews on another pigs tail leading to a wound and bleeding. This abnormal social behaviour is usually associated with deficiencies in the pigs environment, management or nutrition.



Picture: National Pork BoardTo solve a tail-biting problem promptly remove and treat the tail-bitten pig(s). Then review the following questions and determine the most likely causes. If tail-biting continues check other likely causes until the problem disappears.

Environmental Causes of Tail-Biting
Is the building temperature appropriate for the age and weight of the pigs?
Is the ventilation system functioning properly?
Are pigs following appropriate dunging behavior?
Is the building air quality (ammonia and hydrogen sulphide levels) satisfactory?
Are pens dry?
Management Causes of Tail-Biting
Are pigs overcrowded?
Can pigs lie comfortably?
Has mixing of pigs between pens occurred?
Is the electrical supply properly grounded and stray voltage eliminated?
Nutritional Causes of Tail-Biting
Was the feed properly formulated for levels of salt and other vitamins and minerals?
Are there a sufficient number of drinkers with adequate flow rate per pen?
Is there adequate feeder space?


大概分成三個部分----環境, 管理跟營養
環境---空氣質量,流動,不良氣味,溼度,溫度
管理---飼養密度,混欄
營養---礦物質維生物量,飲水器數量,採食空間

很'常識耶  ..答了一定又被幹焦    鹽與乳清粉的問題  +一點油脂

ps:
沒寫清楚   又以為油脂要加多   ....???

Ergot alkaloids 麥角毒素
Reduced growth
Vertigo, staggers, convulsions, temporary posterior paralysis
Decreased peripheral blood supply :070 末梢循環變差
Reduced reproductive efficiency of sows
Eventual death  懷孕末期死產

如果飼料中不處理~耳朵尾巴會呈"臭火搭"~(燒焦狀)~
一般並隨導致咬耳咬尾!~
