Hog Cliolara Prevention 141 



be made of the bedding exposed hogs are delivered to the rail road stock 

 yards on. Some states say the buyer must burn it in the yards, etc. 

 Most states have laws concerning the sale of sick hogs, and the disposi- 

 tion that must be made of the dead hogs. In fact there are enough laws 

 in most states. In Missouri, it is illegal, according to the act of the 

 Missouri legislature, 1917, to sell sick hogs of any kind. (2) It for- 

 bids the driving or handling of sick hogs. (3) All dead hogs must be 

 burned within 24 hours. 



But with all the efforts of the legislature, experiment stations, san- 

 itary boards, etc., the farmer will continue to suffer an average loss of 

 $50,000,000 a year unless he takes much more precaution along the right 

 lines in the future than he has in the past. Just as long as the farmer 

 depends on drug or grocery store treatment, such as lye, stock foods, 

 worm remedies, etc., to keep away the cholera, he'll lose his hogs. 



Where is the farmer that believes he can feed such feeds and I can 

 not give his hogs cholera by feeding them the organs of diseased 

 hogs. There's not one farmer in fifty that would permit me to put such 

 preventatives to any such tests. Yet farmers hold to it that those very 

 things kept the cholera away. 



Oh! you feed such things to keep your hogs healthy and thus pre- 

 vent cholera, my observation has been, the hogs tliat are making the most 

 rapid growth are as subject to the disease as any of the others, so to keep 

 a hog healthy doesn't prevent hog cholera. 



There are only two ways to prevent it. One is, to keep the infection 

 of die diseased pens away from the well hogs and by the use of anti-hog 

 cholera serum. 



The former method is sane, safe, dependable and cheap. The lat- 

 ter is dependable and somewhat expensive. 



SERUMS 



You may at some time have used serum and it did not save your 

 hogs, so you would say it was not dependable. First, why, was it not 

 dependable? If serum is kept at summer or early fall temperature, in 

 a few days it loses its immuning powers. It should be kept close to 40 

 degrees. All veterinarians did not know this when they first began to 

 use serum. Again, many people did not use serum in large enough 

 doses and the hogs died. Some companies did not put out a first class
