How to diagnose and identify whether a sheep has rheumatism?

If a sheep is found to have rheumatic disease, a diagnosis should be made first. If it is a disease, it should be prompted**. At the same time, the feeding environment of the affected sheep should be adjusted to ensure that the sheep house is dry, hygienic and well ventilated. Let's take a look at the diagnosis, differentiation and solution of sheep rheumatism.

How can you tell if a sheep has rheumatism?

At the time of diagnosis, the following two features should be noted.

1.The affected area is not limited to one place, often wandering, often invading the hind limbs, so it often manifests as waist stiffness.

2.Claudication is characterized by small steps and a stiff gait. Claudication is noticeable at the beginning of walking and decreases or even not noticeably after walking for a while.

3.Differential diagnosis: should be distinguished from cerebrospinal fluid filariasis, calcium deficiency, and tetanus.

Rheumatism. Pathogenesis: 1. Limp, only acute patients suddenly can't get up.

Characteristics of the affected limb: muscle tension, stiffness, metastasis, and pain response to local compression. Body temperature:

Acute cases are elevated. Appetite: Loss of appetite in acute cases.

Encephalomyelitis filariasis. Pathogenesis: Very sudden.

Characteristics of the affected limb: no tension, no stiffness, no metastasis, no pain response to pressing the muscles. Body temperature:

Not elevated. Appetite: Unaffected.

Over time, it will gradually decrease due to inactivity.

Calcium deficiency. Pathogenesis: From inconspicuous claudication to pronounced claudication, lying on the ground very thin. Characteristics of the affected limb: not hard or tense, sometimes head and leg deformities can be seen, and the joints become larger. Body temperature: not elevated. Appetite: Gradually decreased.

Tetanus. Pathogenic process: rapid development. Characteristics of the affected limb: the limbs are straight, and the joints cannot be bent. Body temperature: not elevated. Appetite: Rapidly reduced to complete extinction, jaw closed.

In addition, seasonality and endemism should be considered in the differential diagnosis. For example, cerebrospinal filariasis is very seasonal, and the incidence is mostly in July and October when there are many mosquitoes; Rheumatism is more common in cold and humid conditions in autumn and winter, but it can also occur in the absence of mosquitoes; There is no significant seasonality for calcium deficiency and tetanus. As long as the feed is deficient in calcium or the ratio of calcium to phosphorus is imbalanced for a long time, calcium deficiency can occur, which is often endemic (high groundwater level, soil calcium deficiency).

You can tell if you have rheumatism by the location of the pain, and if you have pain in the joints on a rainy day, it is likely to be rheumatism.

The affected part is not limited to one place, it is often migratory, and it often invades the hind limbs, so there is often a stiffness in the waist.

Claudication is characterized by short gait and a stiff gait. The claudication is significant at the beginning of walking, and the claudication decreases or is even less noticeable after a period of walking.

Differential diagnosis: it should be distinguished from cerebrospinal filariasis, calcium deficiency, and tetanus.

It should be observed from the usual details, whether the sheep has some bad behaviors, or there will be some abnormal behaviors from before, and it is also necessary to observe whether the sheep has lost appetite or has inconvenient legs and feet.
