SYMPTOMS OF RHEUMATISM IN SHEEP. 



Articular rheuinatism seems to be very rare in mature sheep, 

 while it has been recorded in lambs. Muscular rheumatism on 

 the other hand has been seen in connection with untimely shear- 

 ing, exposure to cold storms and cold, damp folds. The back 

 and loins, are tender to the touch, or in other cases the neck or 

 hind quarter, the limbs are carried straight and rigid, the animal 

 moves slowly and stiffly, falls behind the flock, and is found alone, 

 unthrifty and emaciated. It usually terminates in recovery 

 though it may cause chronic disease and distortion of the affected 

 joints or it may even prove fatal. The usual tendency of the 

 morbid process to shift from joint to joint or to muscles, is here 

 again characteristic. 



SYMPTOMS OF ARTICULAR RHEUMATISM IN SWINE. 



Climatic influences. Rheumatoid. Joints attacked. Mu.scles. Decu- 

 bitus. Stiff, rigid, steps on toes, grunts, swelling, heat, tenderness, chaps, 

 cracks, suppurations, inappetence. emaciation, metastasis, cardiac disorder. 

 Duration ; course. Chronic form. Muscular form. Diagnosis from trichi- 

 nosis. Connection with arthritis. Metastasis. Remissions. 



The pig which shows an extreme sensitiveness to climatic 

 vicissitudes and cold winds, fleeing instantly to his lair on their 

 advent, is yet protected by his subcutaneous fat, so that he is not 

 a freqtient victim of simple rheumatism. Leblanc attributes it to 

 unwholesome pens. Chaussade to too rapid fattening (overfeed- 

 ing). Rheumatoid attacks are very common at the onset of hog 

 cholera, swine plague and other infectious di.sea.ses, when thej' 

 are probably but local manifestations of the general infection. 



The lesions are mainly concentrated in the stifle, hock, knee 

 and fetlock. In some ca.ses the dorsal and lumbar mu.scles suffer 

 and there is arching of the back with great tenderness on manip- 

 ulation. In other cases the muscles of the quarter or shoulder 

 are involved as shown by their stiffness and extreme sensibility to 

 touch.
