你可以停用驅蟲藥,
"免疫抗毒素"拌料!
碘消毒液直接涂抹患處!效果不錯!我已治愈很多類似病歷!
你可以試試!

我明白的啊，他們也是為了吃飯嘛，故事應該從很早的雞的傳染性腺胃炎開始吧--那是職業人士制造的疾病！

唉，難的就是這些窟窿有人搞出來了，卻沒人搞定。

樓主,你的豬今天怎么樣啊?現在用藥了嗎?

保育豬仍有散發，一棟幾欄一欄幾頭這樣。
現加強消毒，注射驅蟲藥。搞不懂一個新場會有這么多病？！

寄生蟲感染的可能性不大

“重癥的育成豬和肥育豬最特征性的癥狀是皮膚病的發生和擴大，主要是胸部、腹部、大腿和前肢廣泛的皮炎，出現許多大小不等的紫紅色腫塊并逐漸蔓延擴大。病豬精神沉郁、大多數發生高熱、行動和采食遲緩、伴有嚴重的呼吸困難。死亡率常為15%或更高。耐過本病的豬往往生長發育不良。死后剖檢可以看見腹腔內淋巴結發紅、腫大腹水帶留。病理解刨共同的特征性病變是腎臟可見許多小的出血性斑點”

這是資料對PDNS的描述，“病豬精神沉郁、大多數發生高熱、行動和采食遲緩、伴有嚴重的呼吸困難”，想文樓主有嚴重的呼吸困難癥狀出現沒？

是不是由于疥螨引起，看了許多豬場，
都有類似癥狀，
主要發現在育成，育肥及部分母豬，
仔豬很少發病，
也沒化膿現象

死亡率不高可排除PDNS吧，

癥狀
斷奶豬與生長豬
Appearance of extensive greasy brown, purplish red slightly raised blotches of various sizes and shapes over the chest, abdomen, thighs and forelegs. The majority of pigs that develop extensive skin blotching die.
Over time the blotches become covered with dark infected crusts (dermatitis) and then fade leaving scars.
The pigs are depressed.
May have a fever.
They are usually reluctant to move.
Lose weight
Sometimes breath heavily.
Mortality high.
Loss appetite.
仔豬 & 母豬
Rare
致病原因
The cause is unknown.
It is not known how the disease spreads between pigs or between herds or what triggers off a clinical outbreak. However sources of incoming pigs must come from herds with no history of disease.
診斷
The clinical signs are strongly suggestive but not diagnostic. Gross and microscopic post mortem examinations are needed to make a firm 診斷. At gross post mortem examination lymph nodes, particularly those at the rear of the abdomen which are not usually examined, are reddened and enlarged and there is often fluid in the abdomen. The most consistent lesions are in the kidneys which are swollen, pale and mottled with many small haemorrhages showing through the surface. Tests can be done for high urea and creatinine levels in the blood which indicates severe kidney damage. These tests may be negative if the kidneys are less severely affected. Microscopically, the lesions in the blood vessel walls are distinctive. Since the cause is unknown there are no specific diagnostic tests.


Similar diseases
Classical swine fever (CSF), (Hog cholera), or African swine fever (ASF). Other diseases which might be confused with PDNS include erysipelas and Actinobacillus suis. Other kidney conditions may also be confused with PDNS.

我覺得抗生素用多了，豬腎虧，一代傳一代，我現在越來越反感抗生素！！！！
