being especially suitable for weak animals. Provide clean quarters and 
wholesome food, and. observe care in promoting a healthy condition of the 
stomach and bowels. Note the remarks on tape-worm under Measles. 
DISORDERS FOLLOWING CASTRATION AND SPAYING. 
It is useless in a work of this kind to give directions upon the various 
methods of performing these operations, They are matters of practice, to 
be learned by witnessing the operation. It may be said that boar-pigs 
should be castrated after the tenth day and before the third month is passed. 
The best age for operating on a sow-pig is perhaps six weeks. One should 
seek to have the pigs in good health at the time, and so far as possible 
choose weather that is neither very warm nor very cold, and preferably not 
wet. After the operation, it is well to confine the animals for a few days to 
keep them from getting into water and mud before the sore has healed, 
Provide good shelter, with plenty of clean bedding. Sour milk or whey 
and barley-meal make a good feed. High feeding after the operation is 
very unwise and dangerous. It is not unfrequently the case that the ani- 
mal, some time after the operation, evinces signs of lock-jaw (spasmodic 
motion of the head and of one or more legs, grinding of the teeth and stiff- 
ness of the jaws), and then the treatment for Lock-Jaw is tc be adopted. 
GENERAL MENTION OF DISORDERS. 
As remarked on a preceding page, the hog is subject to many disorders 
which are common to the horse, ox and sheep, and hence do not need sepa- 
rate treatment. Among them we mention Paralysis, a partial or complete 
loss of some of the members, as a leg; Diarrhea, a simple looseness of 
the bowels as a result of improper food, a cold, or some constitutional dis- 
‘ease; Dysentery, or Bloody Flux, which is an inflammation or ulceration of 
the membranes of the intestines, attended with blood discharges, much 
. pain, and rapid prostration; Stone in the Bladder; Inversion of the Blad- 
der; Inflammation and Enlargement of the Spleen; Protrusion of the 
Rectum; Erysipelas; Lice; Mange or Itch; Ruptures; Injuries in gen- 
eral. The most of these are readily recognized, and the reader will find 
their causes, symptoms and treatment sufficiently considered by reference 
to the articles upon the same disorders in the Horse.
