Donkey and Mule|10 Common Diseases (cause → signs → examination → treatment direction → prevention)
Ten common diseases of the donkey and mule (Equus asinus and donkey-horse hybrids) gathered into one table: Hyperlipemia/Hyperlipidemia Syndrome (a severe condition particular to donkeys), Colic, Laminitis, respiratory disease (within the equine influenza/RAO range), dental disease, internal parasite burden, obesity and metabolic syndrome, depression-like behavioural reaction (after the death of a companion), skin/external parasites, and hoof infection (Hoof abscess/Thrush). Each row lists cause, signs, examination, treatment direction and prevention; the treatment column gives categories only, never doses. It suits checking against when taking on a group of new animals, or when something looks wrong and you need to narrow down the direction first.
Donkey and Mule|10 Common Diseases (cause → signs → examination → treatment direction → prevention)
This content is compiled from the disease table for the donkey and mule (*Equus asinus* and donkey-horse hybrids) in the farm animals and horses chapter of the veterinary animal encyclopedia. The same sign calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.
| # | Disease (Chinese/English) | Cause | Signs | Examination | Treatment direction | Prevention |
|---|---|---|---|---|---|---|
| 1 | Hyperlipemia/Hyperlipidemia Syndrome (a severe condition particular to donkeys) | Once a donkey's appetite drops or feeding stops for any reason (pain, stress, another illness), body fat is rapidly mobilised into the blood beyond the liver's capacity to metabolise it, setting up a vicious circle | Anorexia, lethargy, jaundice, rapid deterioration | Blood triglyceride and liver function testing | An emergency requiring immediate veterinary care, with aggressive nutritional and metabolic support; medication must be prescribed | Any drop in a donkey's appetite should be treated as a warning sign calling for prompt veterinary attention, not a wait-and-see |
| 2 | Colic | As for the horse (A); the mechanism is the same | As for the horse, but because donkeys are stoic by nature the outward signs may be milder and therefore underestimated | As for the horse | An emergency requiring immediate veterinary care | As for the horse: gradual feed transitions, ample water, regular parasite control |
| 3 | Laminitis | As for the horse; the donkey's tendency to obesity makes the risk comparatively higher | As for the horse, but the donkey's stoic nature may delay detection | As for the horse | An emergency requiring immediate veterinary care | Control body weight, restrict high-sugar forage |
| 4 | Respiratory disease (within the equine influenza/RAO range) | As for the horse | As for the horse | As for the horse | As for the horse | As for the horse: ventilation, low-dust bedding |
| 5 | Dental disease | As for the horse; the same lifelong growth mechanism | As for the horse | As for the horse | Routine floating | Regular oral examination |
| 6 | Internal parasites | The same mechanism as in the horse | Weight loss, poor coat | Faecal egg count | Anthelmintics must be prescribed | Individualised parasite control |
| 7 | Obesity and metabolic syndrome | Donkeys are metabolically efficient and keepers often overfeed them | Overweight body condition, increased risk of laminitis | Body condition scoring, blood testing | Dietary adjustment requires veterinary guidance | Adjust the ration to the donkey's low energy requirement |
| 8 | Depression-like behavioural reaction (after the death of a companion) | Strong companion attachment, and the loss of that companion | Refusal to eat, greatly reduced activity | Assessment after ruling out physical causes | Combined veterinary and behavioural assessment and intervention are needed | Avoid keeping a donkey alone long term, and provide a new companion promptly |
| 9 | Skin parasites/external parasites | Mites, lice and the like | Itching, hair loss | Microscopy of skin scrapings | Medication must be prescribed | Environmental hygiene management |
| 10 | Hoof infection (Hoof abscess/Thrush) | Damp, dirty conditions, insufficient hoof trimming | Lameness, foul-smelling discharge from the hoof | Hoof examination | Handling by a veterinarian or farrier is required, and medication must be prescribed | Regular trimming, dry bedding |

Limits of this content
This content comes from the farm animals and horses chapter of the veterinary encyclopedia (see the evidence chain for the original location and content hash). The sources at the end are the authoritative materials cited by that chapter; the correspondence is at chapter level, which does not mean every sentence is traced sentence by sentence back to a given source. This material is for education and cannot replace diagnosis and prescription by a practising veterinarian; in an emergency, seek veterinary care immediately. This text has not been clinically reviewed by a named veterinarian.
FAQ
- What is hyperlipemia/hyperlipidemia syndrome (a severe condition particular to donkeys), and what should make you call the vet at once?
- Once a donkey's appetite drops or feeding stops for any reason (pain, stress, another illness), body fat is rapidly mobilised into the blood beyond the liver's capacity to metabolise it, setting up a vicious circle. You will see anorexia, lethargy, jaundice and rapid deterioration. The direction of management is that this is an emergency requiring immediate veterinary care, with aggressive nutritional and metabolic support, and medication that must be prescribed. In the source chapter this row belongs to the group needing prompt attention; the actual judgement still rests with the veterinarian case by case, and this text gives no drug names or doses.
- 高脂血症 Hyperlipemia/Hyperlipidemia Syndrome(ロバ特有の重症疾患)とは何ですか。何が見えたらすぐ獣医師を呼ぶべきですか。 — ロバは何らかの理由(疼痛、ストレス、他の疾患)で食欲が低下し、あるいは採食を止めると、体脂肪が急速に血中へ動員され、肝臓の代謝能力を超えて悪循環を形成することが原因です。食欲廃絶、嗜眠、黄疸、急速な悪化が現れます。対処の方向性は、救急疾患でありただちに受診が必要というもので、積極的な栄養・代謝の支持が必要、薬剤は処方が必要です。この行は元の章で速やかな対応を要する類型に属します。実際の判断は個々の症例に応じて獣医師が行う必要があり、本文では薬剤名と用量は書きません。

- What is colic, and what should make you call the vet at once?
- As for the horse (A); the mechanism is the same. You will see what you would see in the horse, but because donkeys are stoic by nature the outward signs may be milder and therefore underestimated. The direction of management is that this is an emergency requiring immediate veterinary care. In the source chapter this row belongs to the group needing prompt attention; the actual judgement still rests with the veterinarian case by case, and this text gives no drug names or doses.
- 疝痛 Colic とは何ですか。何が見えたらすぐ獣医師を呼ぶべきですか。 — ウマ (A) と同じで、機序も同じです。ウマと同じ症状が現れますが、ロバは我慢強い性質のため、外に現れる症状がより軽く、過小評価されることがあります。対処の方向性は、救急疾患でありただちに受診が必要というものです。この行は元の章で速やかな対応を要する類型に属します。実際の判断は個々の症例に応じて獣医師が行う必要があり、本文では薬剤名と用量は書きません。

- What is laminitis, and what should make you call the vet at once?
- As for the horse; the donkey's tendency to obesity makes the risk comparatively higher. You will see what you would see in the horse, but the donkey's stoic nature may delay detection. The direction of management is that this is an emergency requiring immediate veterinary care. In the source chapter this row belongs to the group needing prompt attention; the actual judgement still rests with the veterinarian case by case, and this text gives no drug names or doses.
- 蹄葉炎 Laminitis とは何ですか。何が見えたらすぐ獣医師を呼ぶべきですか。 — ウマと同じで、ロバは肥満傾向があるためリスクは相対的に高くなります。ウマと同じ症状が現れますが、ロバの我慢強い性質のため発見が遅れることがあります。対処の方向性は、救急疾患でありただちに受診が必要というものです。この行は元の章で速やかな対応を要する類型に属します。実際の判断は個々の症例に応じて獣医師が行う必要があり、本文では薬剤名と用量は書きません。
