428 HORSE, SWINE AND POULTRY DISEASES 



changed and ulcers form. Severe outbreaks are known as malig- 

 nant catarrh. Nasal catarrh does not run a well defined course and 

 may extend to other parts of the respiratory track. 



Treatment. In the simple form of the disease medicinal treat- 

 ment is not necessary. The hog should be fed warmed slop for a 

 few days and a laxative (castor oil) administered. In severe cases 

 in addition to this, inhalations of medicated steam (turpentine or 

 creolin) may be given. (Ind. B. 100.) 



SORE THROAT. 



The causes and symptoms of inflammation of the pharynx and 

 larynx in the hog are very much the same. This is also true of ton- 

 silitis, and usually, all of these structures are involved at the same 

 time, and can be discussed conveniently under the one head, sore 

 throat. 



Causes. Sore throat frequently occurs as a complication of a 

 bad cold. In addition to those already mentioned as causes of cold 

 in the head are wallowing in cold springs and creeks when warm, 

 being deprived of water and slops during a warm, dry season, close 

 filthy pens, debility, entrance of septic germs along with the food 

 and germs of hog cholera and swine plague. 



Symptoms. There is more or less fever, the eyes are red and 

 watery and the animal is dull and may lie around the pen most of 

 the time with its head buried in the litter. The appetite is poor and 

 the hog may refuse food, because of the pain and difficulty in swal- 

 lowing. Sometimes there is considerable restlessness. The respira- 

 tions are noisy and the throat swollen. The cough may be dry, 

 hard or spasmodic in character, often quite hoarse. There may be a 

 discharge from the nose or mouth. In septic poisoning in the food 

 and in infectious diseases, false membranes may form or the mu- 

 cous membrane become gangrenous. The disease may develop 

 rapidly and the air passages become closed by the swelling in a few 

 hours and the pig die. Sometimes the animal dies as a result of the 

 local ulceration or from general infection. In the less severe cases 

 the disease runs a course of a week or more. In this latter form, if 

 not caused by pathogenic organisms, recovery usually occurs. 



Treatment. The sick hog should be isolated from the healthy 

 ones and given clean, dry, comfortable quarters. This part of the 

 treatment is very important if the inflammation is due to septic or- 

 ganisms. Sloppy food should be fed and in cold weather it is best 

 to feed it warm. Mild stimulating liniments can be applied to the 

 throat. Sometimes a blistering ointment (powdered cantharides 

 one part and vaseline eight parts) is applied to the skin in the 

 region of the throat. An electuaria is made of syrup three ounces 

 and tincture of aconite (two drams), can be given in teaspoonful or 

 tablespoonful doses thrice daily. By confining the hog with a noose 

 around the upper jaw the throat can be swabbed out with antiseptic 

 washes (silver nitrate one part, water one hundred parts), or per- 

 manganate or potassium (two parts, water ninety-eight parts). It 

 is best to make the handle of the swab of wire or the hog may bite
