Round Worm in Hogs
By DR. c. Fl. CONN n Swine Breeders Journal

 | The scientific name for the common
 round worm of hogs, that is so widely
 and commonly found in our American herds is, ascoris snilla. i This worm is pinkish or yellowish-
 white in color. and the body is firm and elastic and tapers at each end. The fe-
 male is larger than the male and will av- 1 craze Ii inches in length, while the male will average from to 19 inches in length. The male has a curled tail, while the | female has a straight one.
 | These worms have a complete diges- l tive system and are able to take up food
 from the intestinal tract and use it for themselves
 The female lays large quantities of eggs in the ntestines of the hog, and becoming mixed with the intestinal con tents they are passed out of the body lstn the feces. These eggs are too small su n seen with the naked ey. Thse eggs 5trr raching the ground becom mixed t the earth and water, and then they aken up by other hogs with the feed
 at 5rinking water The digestive fluids le stomach dissolve these eggs from
 hell in which they are inclosed and 31Af pass into the <intestines where they
 q lily develop into full-sized worms,
 Ultg pigs are more susceptible to this
 cau ition than older hogs.
 ing from dirty feeding floors, drink ing contaminated water from mud holes and stagnant pools or from dirty troughs
 are predisposing causes of this disease. Any condition in the pig that produces digestive troubles or general unthriftl- ness, will also predispose young hogs to this infestation
 It is not always possible to determine that hogs have these worms in the in
 testinal tract from the symptoms they
 show. However, if we find forms in the feces this is conclusive and undisputabe evidence that they are infected. Thxe are some symptoms that are suspicious ot this condition, and they are slight riar rbea, some -iregularity in appetite, and in very bad cases the animal may surfer coliclzy pains, restlessness and rapidly looses flesh. If hogs in this condition are carefully observed, they can usually be detected as passing worms Tn the feces.
 Hogs should be fed on tight. clean floor: preferably a concrete one. No mud holes or pools of stagnant water should be permitted and the feed lot should be well drained; all litter ana trash should be collected and~removed or burned: the ground should be thoroughly Timed or sprinkled with per cent so- lution of good dislnfectant. fresen',oi offers the best and most practical soiu- tion to the handling of round worm in- | fectation of hogs.
 The giving of medicine to hogs by way 1 of the mouth is a very unsatiS1actory plo- l cedure. The best way to meohcate hoss | Is through the feed or slop There are several procedures that must be care | fully observed to insure the success or medicines given in this way, It IS | good practice to keep all feed away rom I the animals for at least A hours prior | to giving the medicine and then it1ls pes. | to give it to about 10 hogs at tune. When it is given to large herd all at one time the strong ones get an over | dose and the weak ones get very little 1T any So if is best to have the mediolne put up in doses for 10 hogs and then mix it with quantity of slop and reed I it to them. Santonin and calomel are two very good drugs and should be given together, sS- | ing 6 grains of santonin ana grams oi calomel for each 100 pounds of live weish.; l tbus for 10 pigs weighing 100 pounds each
 we vonld dissolve 60 grains of santonln and 40 grains of calomel. This can De | dissolved in milk but not in water; miN
 with slop and feed These drugs are very l expensive at present.
 l Spirits of turpentine is very soou
 drug and can be employed mixed .wltn milk after the animal has been ias'eu i 94 hours From two teaspoonfpls to one itablespoonful for each hog of rom " hounds tip. This should be followed m r. two or three hours with dose or epSohi 1 salts or linseed oil in the sioR
 Beechwood creosote is another good
 rrrm destroyer and may be given III
 doses of from 10 to 25 drops to each nog' | a S1o-pound hog receiving 10 drops in lin
 sead oiI which is then placed in the slop. rife last two drugs should be repeated every ten days for about three tunes al
 Tsavs given after aN 2i-hour fast ana al ways followed by laxative
