ROUND WORMS 



Cause: Is undoubtedly due to filth or hogs eating 

 food or drinking water contaminated with well developed 

 eggs or embryos of roundworms, thus taking them into 

 their digestive canal, where they multiply rapidly and 

 set up considerable irritation. This worm varies in 

 length from three to thirteen inches, and is of a reddish- 

 brown color. 



Symptoms: The Eoundworm is generally passed 

 with the feces, and can be readily seen with the naked 

 eye. A hog infested with a large number of these worms 

 is generally restless, appetite varied. When these 

 worms develop in large numbers, they obstruct the in- 

 testines. In other cases they irritate and inflame the 

 intestines causing inflammation and diarrhoea, and death 

 may be due to either obstruction or inflammation of the 

 bowels. 



Treatment: Treatment is very satisfactory. With- 

 hold all food from eighteen to twenty-four hours. Then 

 place in one pint of finely ground feed, Calomel and San- 

 tonin, each five grains to every one hundred pounds of 

 hog weight. For instance, if the hog affected with round 

 worms weighs two hundred pounds, double the dose by 

 giving ten grains of each of the above, but if the hog 

 only w-eighs fifty pounds, give one-half the dose men- 

 tioned, or two and one-half grains of each. This treat- 

 ment should be repeated in a week or ten days to assure 

 the expulsion of worms that might have survived the 

 first dose. Feed sparingly on laxative food, as bran 

 mashes and vegetables, for a few days following each 

 treatment.
