108 DISEASES (iF CATTLE. 



pression of the spinal cord, concussion of the brain, or compression 

 of the brain. An injury to one side of the bruin may ]:>roduce 

 inualysis of the same side of the head and of the opposite side of the 

 body (hemijjlegia). Paralysis may occur in connection with par- 

 turient apoiDlexy, lead poisoning, ergotism, etc. 



CONGESTION OF THE SPINAL CORD. 



Paraplegia, or paralysis of the rear part of the body, is the domi- 

 nant symptom in congestion or inflammation of the spinal cord. The 

 cause is not known, but the disease is probably due to chilling. It is 

 thought by some that some toxic influence (poison) may be responsi- 

 ble for its development. 



Sijrivptoms. — The symptoms usually appear suddenly and consist 

 in inability to stand. Sometimes this is preceded b}' a period of 

 excitement. The animal usuall}' lies quietly, but sometimes it groans 

 and tosses its head about in a way that indicates pain. Cows heavy 

 with calf are sometimes affected with a form of i^araplegia, which 

 ijsually attacks them from about a month to a few days before 

 calving. Apparently they are in good health in every respect ex- 

 ce])t the inability to stand up on account of the paralysis of the 

 hind quarters. This form is generally attributed to feeding on feeds 

 containing insufficient protein and ash. It is most likely to occur in 

 cows that are weak and thin. With good care and feed recovery 

 usually occurs. - 



Treutnu'nt. — The animal must be given a soft, dry bed under shel- 

 ter and in a quiet, airy ]>lace. It is well to apply mustard along the 

 spine. The action of the mustard may be intensified by rubbing 

 the skin with ammonia or turpentine. Internally give a purge of 

 Glauber's salt. Xux vomica or strychnia (1 to 2 grain doses) may 

 be given. Turn the cow two to four times daily and rub the legs 

 well each time. 



There are instances when cows will persist in lying down (in spite 

 of all efforts that are made to compel them to stand up), when it can 

 not really be said that they are paralyzed. They haAe sensation in 

 all parts; they can move all their feet; they can change their posi- 

 tion; and in fact every function seems to be normally performed, 

 but they obstinately refuse to rise or even make an effort to do so. 

 Cases of this kind have been killed, as it was an utter impossibility 

 to get the animal on its feet. However, there are instances when a 

 cow, after refusing to rise when all other means had been tried, 

 quickly jum})ed to her leet and showed fright upon the appearance 

 of a dog or other terrifying object.
