2?2 THE DISEASES OF CATTLE. 



Uraemia is the more or less complete cessation of the 

 excretion of the waste products of the body which the 

 kidneys ought to separate from the blood. (Gresswell.) 



It is a serious disease, as the function ordinarily per- 

 formed by the kidneys devolves on the skin, bowels, and 

 liver. The blood contains an excess of waste products. 

 The disease follows inflammation of the kidneys. 



SUPPRESSION OF URINE 



May be complete, though rarely, owing to acute in- 

 flammation of the kidneys. It is often partly suppressed 

 in acute febrile diseases. In certain febrile states there 

 may be a deficient secretion of urine, and what is passed 

 will probably be of high specific gravity. The disorder 

 occurs in draft oxen, in dry countries, and in cattle kept 

 on dry pastures in hot, dry weather. Working oxen, fed 

 on dry food, should have about seven gallons of water 

 daily. Those at pasture should be well supplied also. 



RETENTION OF URINE 



May arise from obstruction or lack of expulsive power, 

 as in paralysis. As a rule the ox is very irritable ; lashes 

 tail ; lifts hind limbs ; lies down often perhaps ; tries to 

 pass water; looks at flanks. Sometimes, however, the 

 bladder may burst without manifestation of much pain. 

 Pass catheter and treat according to circumstances. 



The name dysuria is given to the painful expulsion of 

 urine, and strangury to its passage drop by drop, as in 

 spasm or inflammation of the neck of the bladder. 



A previous condition of the urachus (canal) may cause 

 constant dribbling of urine through the navel. Ligature 

 or stitch. It is most frequent in prematurely born calves.
