are twenty four hours old. In old boars, pincers or a hand saw may be 

 used to get rid of these dangerous weapons. Long handled pincers such 

 as blacksmiths use to trim horses fe«t are excellent to clip the tusks of a 

 boar with. See cut page 17, fig. 14. 



LOCK-JAW, TETANUS 



Lock jaw may develop in a few days or several weeks after castra- 

 tion and is more often caused by castration not being done under sani- 

 tary conditions or lack of proper drainage. Howiever, it might develop 

 from other wounds. 



Lock jaw bacteria can not live in the presence of air hence if the 

 wound heals over it makes a favorable location for lock jaw. 



SYMPTOMS 



The muscles become rigid and the hog is easily startled. They usu- 

 ally can open their mouths sufficient to take liquid foods and sometimes 

 corn. Usually they lose the use of the muscles of the fore or hind 

 quarters separately. 80 to 90 per cent of the cases die. ~ 



There is a tetanus anti-toxin kept by most of the well stocked drug 

 stores for human use. The injection of 400 to 600 units under the skin 

 back of the ear for every 100 pounds of live weight daily until improve- 

 ment develops, in some cases seems to be of benefit. 



SCAB, MANGE, ITCH, SUN SCALD 



Scab is more often met with in younger hogs but may be found on 

 hogs of any age. Pigs nursing a scabby mother often develop bran like 

 itching scales on the face or at the base of the tail before they are a week 

 old. The disease is caused by a mite that burrows under the skin and 

 lives on the blood and lymph of the hog. Wet, hot weather favors the 

 development of the mites. The mites go from one hog to another just 

 as lice get from hog to hog. 



TREATMENT 

 Dip solutions or kerosene emulsion are efficient to destroy the mite
