DISEASES OF SWINE 441 



the formation of pustules. In the more severe form, pustules de- 

 velop and it requires a week or more to make a recovery. The 

 appetite is usually impaired and the hog is feverish. This disease 

 is not contagious. 



Treatment. Two or three ounces of Epsom salts should be 

 given in the feed, and the hogs fed a light sloppy diet. If dirty or 

 lousy, they should be dipped or washed with a watery solution of 

 some of the cresol preparations. In severe cases ten drops of Fow- 

 ler's solution of arsenic should be given twice daily. (Ind. B. 100.) 



ECZEMA, PITCH MANGE. 



Causes. This disease is associated with unhygienic conditions, 

 filthy pens, extremes of heat and cold, and a debilitated condition. 

 It may also occur in specific diseases (hog cholera, articular rheuma- 

 tism, etc.). What seems to be a variety of this form of mange, 

 occurs upon marsh land in the summer, when dry, due to the irri- 

 tation of the soil itch dirt. This is seen frequently in the Kan- 

 kakee region. 



Symptoms. The disease starts by small red spots on the skin. 

 These are followed by vesicles (blisters) which in time become 

 pustular. Finally these dry up and form thick crusts which grad- 

 ually wear down and become thin and branny. All stages of the 

 disease may be seen on the skin at the same time. There is intense 

 itching and the hog may have a slight fever, a poor appetite and 

 act dull. 



Treatment. This consists in bettering the hygienic conditions 

 under which the hogs are kept, and either washing or dipping them 

 in a water solution of some of the coal tar preparations. The wash- 

 ing or dipping should be repeated at frequent intervals. (Ind. B. 

 100.) 



SKIN WARTS. 



Warts are simply piled up epidermal cells and are best removed 

 with a knife. A preparation of a dram of salicylic acid in an ounce 

 of castor oil, rubbed on once or twice a day for a couple of weeks 

 may remove them. (Ind. B. 100.) 



SORE TAILS. 



Causes. The causes of sore tails, and tails dropping off, are 

 cold, filth and injuries. When young the tail may become injured 

 by the mother stepping on it. Sometimes when the pen is filthy 

 bacteria will cause it. Old hogs, when allowed to wallow in the mud, 

 may lose a portion of their tails from the mud balls that accumulate 

 toward the ends. Loss of the tail is frequently associated with an 

 unthrifty condition. 



Treatment. This is preventive. If the pens are filthy, they 

 should be cleaned and antiseptics used freely. The loss of the tail 

 is of little consequence to the ordinary hog, but for those used for 

 other purposes or to be sold as breeders, it becomes a blemish. 

 (Ind. B. 100.) 



RHEUMATISM. 



Articular and muscular rheumatism are so frequently asso- 

 ciated in the hog that it is best to discuss them together. Although
