DISEASES OF SWINE 519 neither the house nor the lots should be used for a time, thus giving the sun sufficient time to destroy all the germs. WORMS Internal worms are of frequent occurrence in swine. They in- habit both the stomach and intestines. These worms interfere with digestion; in consequence the pigs fail to thrive and become pot-bellied, rickety, profitless runts, or quickly succumb to the effects of the worms. Swine infested with worms become an easy prey to more deadly diseases because of their weakened condi- tion. Prevention of worms. — Well-fed swine, in general, are not sub- ject to worms. The strong thrifty pig is usually able to resist the parasites. Hogs having free access to wood ashes, charcoal, air-slaked lime, and coal cinders are not likely to be troubled. The alkali in the wood ashes, together with the grit in the cinders, have a tendency to destroy the worms. Pumpkins, fed seed and all, in the fall also help to keep swine free from worms. Stagnant surface water, in which hogs wallow, are ideal places for the incubation and development of worms. For this reason old pens and pas- tures, if wet, should not be used for hogs. The pens and pastures should be well drained and all stagnant water fenced out or the ponds filled in. The drink- ing water should come from a deep well, and it should be kept pure by using clean troughs so constructed or protected that the hogs cannot wallow in them and fill them with filth. Treatment for worms. — The average herd of pigs is kept under such conditions that it is desirable to dose them at least once during the year with some remedy that will destroy the.
