OTHER PIG AILMENTS. 139 



having access to contents of water closets, or to land fertilized by 

 the contents of water closets. 



TRICHINAE. A disease of man due to eating pork containing 

 trichinae. Thorough cooking destroys the parasite, but infected 

 meat is not safely used, and is condemned at slaughter-house in- 

 spection. 



Prevention. The feeding of hogs upon slaughter-house offal 

 is a cause for spreading the parasites, and should not be prac- 

 tised. Rats are infected by eating slaughter-house offal, and as 

 the rats are frequently eaten by the pig, infection likely often is 

 the result. Exterminate the rats and do not feed offal. 



TUBERCULOSIS (CONSUMPTION). A contagious disease com- 

 mon in man, cattle and not rare in the hog. 



Symptoms. Loss of flesh, cough, diarrhoea, swelling about 

 the head and neck, which may open and discharge with little 

 tendency to heal ; death in from few weeks to months. Post 

 mortem shows various sized tubercles, which may be situated in 

 any part of the body, most commonly in the bowels, lungs, liver, 

 or glands of the neck. 



Causes. Direct contagion from other hogs, but generally 

 from feeding milk from tuberculous cows, or by eating butcher 

 offal from such cows. 



Prevention. Care as to the source of the milk fed ; if suspi- 

 cious, boiling will render it safe. Do not feed butcher offal ; sep- 

 arate suspicious hogs at once, and if satisfied they are tubercu- 

 lous, kill and bury deep, or burn them. The tuberculin test can 

 be applied to the remainder of drove, as without it it is impos- 

 sible to say how many may be diseased. 



WOUNDS generally heal readily in the hog if kept clean and 

 free from maggots. The result of neglected castration wounds 

 is sometimes serious. Have the animal clean as possible when 

 castrated, and endeavor to keep it clean and give opportunity for 

 abundant exercise until wound is healed. There is probably 

 nothing better and safer to apply to wounds of the hog than 

 creolin one part, water six parts. 



TRAVEL SICKNESS. Similar to ordinary sea-sickness in man ; 

 very common in shipping pigs by wagon. 



Symptoms. Vomiting, diarrhoea, great depression ; seldom if 

 ever fatal. May be rendered much less severe by very light feed- 

 ing before shipment.
