一農(nóng)戶養(yǎng)殖長毛兔200只，剪毛后三天死亡50多只，經(jīng)過現(xiàn)場解剖和實驗室檢測確定為剪毛引起的應激和通風不暢引起的急性巴氏桿菌和波氏桿菌混合感染。

　　A farmer raised 200 long haired rabbits, and more than 50 of them died three days after shearing. After on-site dissection and laboratory testing, it was determined that the acute mixed infection of Pasteurella and Bordetella was caused by stress and poor ventilation caused by shearing.

　　原因：看似由于疾病引起的死亡，其實仔細分析主要原因還是應激， 秋季以后進行了封棚，封棚以后雖然保暖得到保障可是沒有把通風和環(huán)境考慮進去，剪毛沒有提前做好準備，引起應激。 秋季剪毛要提前做好保暖和應激處理。

　　Reason: Although death may seem to be caused by illness, upon careful analysis, the main cause is still stress. After autumn, the shed was sealed off, and although warmth was ensured, ventilation and environment were not taken into account. The shearing was not prepared in advance, which caused stress. During autumn shearing, it is important to prepare in advance for warmth and stress management.

　　解剖癥狀：肺部出血嚴重，氣管粘膜出血，腸道黏膜充血和出血，腹腔內(nèi)有大量積液，有的肺內(nèi)有膿包，沒有腹瀉癥狀。實驗室確診為急性巴氏桿菌為主的混合感染。

　　Anatomical symptoms: Severe pulmonary bleeding, tracheal mucosal bleeding, intestinal mucosal congestion and bleeding, large amount of fluid accumulation in the abdominal cavity, some with abscesses in the lungs, and no diarrhea symptoms. The laboratory confirmed mixed infection mainly caused by acute Pasteurella.

　　處理：加強通風和消毒，注意消毒以前要根據(jù)天氣，要在天氣晴朗和溫度變化不大的時間進行消毒，在進行剪毛前要防止應激（電解多維和環(huán)丙沙星）和進行消炎處理。

　　Solution: Strengthen ventilation and disinfection. Before disinfection, it is important to follow the weather conditions. Disinfection should be carried out during clear weather with minimal temperature changes. Stress prevention measures (such as electrolysis and ciprofloxacin) and anti-inflammatory treatment should be taken before shearing.

　　剪毛的時間要計劃好，盡量選天氣暖和的時候剪毛，要在上午剪毛，下午太晚了盡量不要剪，上午剪了毛后，到晚上這段時間讓適應。剪毛以后給兔子喝一點溫水，吃點抗應激的藥物。遇到冷空氣的時候盡量不要剪毛， 秋天長的時間長點對兔子對兔毛質(zhì)量都有好處。如果需要剪毛，可以采取剪被部留腹部，也可以剪腹部留背部的辦法，還可以剪左邊留右邊，或者剪右邊留左邊。等另一半兔毛長一點再剪留下的一半，這種剪毛的方法非常適合用電推子剪毛，因為用電推子剪毛剪的太短，把兔子身上的毛全部剪光，兔子受不了。這樣剪毛稍微麻煩一點，可是對兔子健康很有好處。非常好是在大冷到來以前把兔毛剪掉，非常冷的時候不用剪毛，非常冷的天氣，時間就是那一段， 秋天的兔毛長點對兔子沒有影響。

　　The time for shearing should be planned carefully, preferably during warm weather. It should be done in the morning and not in the afternoon if it's too late. After shearing in the morning, it's time to adjust in the evening. After shearing, give the rabbit some warm water to drink and take some anti stress medication. Try not to cut your fur when encountering cold air, as a longer autumn season is beneficial for both rabbits and the quality of their fur. If you need to shave, you can choose to cut the quilt and leave the abdomen, cut the abdomen and leave the back, or cut the left side and leave the right side, or cut the right side and leave the left side. Wait for the other half of the rabbit's fur to grow a little longer before cutting the remaining half. This shearing method is particularly suitable for using an electric clipper to cut the fur, because using an electric clipper to cut the fur is too short, cutting off all the fur on the rabbit's body, which the rabbit cannot bear. This shearing is a bit more troublesome, but it is very beneficial for the health of rabbits. It is best to cut off the rabbit hair before the arrival of the great cold. There is no need to cut the hair during the coldest weather. The coldest weather is during that period, and growing rabbit hair in autumn has no effect on rabbits.
