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 kidneys 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 in 
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 which 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
