ISCHURIA (SUPPRESSION OF URINE). 



This is not a common disease among pigs. Sup- 

 pression or scanty passages of urine is a result of 

 over'-stimulation of the kidnej^s or feeding innu- 

 tritious food; also such medicines as cantharides, 

 turpentine, wood ashes, etc. In all kinds of fever 

 there will be more or less suppression. When the 

 urine is scanty it is irritant and is passed off in 

 drops. It may also be caused by a plugging up 

 of the kidneys by fat. If there is true suppression 

 of urine, symptoms of blood poisoning will occur, 

 "uraemia.-' In cases of suppression the animal does 

 not strain as it will do in retention, the urine pass- 

 ing away in drops or in small quantities without 

 any effort of the animal. If this continues for a 

 day or two the animal will show symptoms of be- 

 ing sick, and if not relieved, will soon die, either m 

 a state of coma or convulsions. 



Treatment: In such cases find the cause, if pos- 

 sible, and remove it. If this cannot be done (which 

 in the pig is often difficult) treat the symptoms. 

 One of the first things is to give a physic and in 

 this way rid the system of some of the effete mat- 

 ter whi^h is sure to be present in the blood, and 

 nothing is better for this purpose than sulphate of 

 magnesia in doses of from one to two ounces. If 

 there is high fever with a full pulse give three to 

 five drops of tincture of aconite at a dose every four 

 hours. If the pulse is weak and the heart irregu- 

 lar, give from two to three drops of fluid extract 

 of digitalis and a teaspoonful of spirits of nitrous
