你可以停用驱虫药,
"免疫抗毒素"拌料!
碘消毒液直接涂抹患处!效果不错!我已治愈很多类似病历!
你可以试试!

我明白的啊，他们也是为了吃饭嘛，故事应该从很早的鸡的传染性腺胃炎开始吧--那是职业人士制造的疾病！

唉，难的就是这些窟窿有人搞出来了，却没人搞定。

保育猪仍有散发，一栋几栏一栏几头这样。
现加强消毒，注射驱虫药。搞不懂一个新场会有这么多病？！

寄生虫感染的可能性不大

“重症的育成猪和肥育猪最特征性的症状是皮肤病的发生和扩大，主要是胸部、腹部、大腿和前肢广泛的皮炎，出现许多大小不等的紫红色肿块并逐渐蔓延扩大。病猪精神沉郁、大多数发生高热、行动和采食迟缓、伴有严重的呼吸困难。死亡率常为15%或更高。耐过本病的猪往往生长发育不良。死后剖检可以看见腹腔内淋巴结发红、肿大腹水带留。病理解刨共同的特征性病变是肾脏可见许多小的出血性斑点”

这是资料对PDNS的描述，“病猪精神沉郁、大多数发生高热、行动和采食迟缓、伴有严重的呼吸困难”，想文楼主有严重的呼吸困难症状出现没？

是不是由于疥螨引起，看了许多猪场，
都有类似症状，
主要发现在育成，育肥及部分母猪，
仔猪很少发病，
也没化脓现象

死亡率不高可排除PDNS吧，

症状
断奶猪与生长猪
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.
仔猪 & 母猪
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.
诊断
The clinical signs are strongly suggestive but not diagnostic. Gross and microscopic post mortem examinations are needed to make a firm 诊断. 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.
