306 DISEASES OF SWINE 



all means never allow such a person to enter your feed lots. It 

 should be forbidden by law to haul dead cholera hogs along the 

 public highway. Such work spreads the disease over miles of terri- 

 tory that might otherwise have escaped the disease. 



(29) Divided Hog Lots. — It would seem an excellent practice 

 where large herds of hogs are kept to make some division of the 

 herd into smaller lots, keeping them separated from each other by 

 a considerable space. This means a little extra expense, and makes 

 the work of caring for them a little more labor, but it would seem 

 to be money well spent, as by so doing we are frequently able to cut 

 the losses from cholera down to a small fraction of what they would 

 be in case the entire herd was in one feed lot when cholera broke 

 out among them. 



In using separate feed lots, however, it must be remembered 

 that should cholera break out in one pen, you can very easily carry 

 it from this pen to another on your boots or shoes if you travel 

 from the infected pens to a healthy pen in feeding. In such cases as 

 this always feed the animals in the healthy pens first, and make the 

 visit to the infected pen last. It is well to have a pair of rubber 

 boots for use in the infected pens, and these can be afterward thor- 

 oughly cleaned with a strong disinfectant solution, such as liquor 

 cresohs compound. 



(30) Running Streams. — Always remember that the running 

 stream is a constant source of danger, not only to your hogs, but to 

 other animals as well. Running streams which pass through your 

 pastures also pass through many other pastures higher up in their 

 course, and receive drainage from many infected lots during an 

 outbreak of cholera. If you have such a stream running through 

 your pastures it is almost certain to carry cholera to your herd 

 sooner or later. 



(31) Hog-cholera Medicines. — Most of these preparations are a 

 fake pure and simple. Few if any of them have any real value. 

 What good they possess, if any, is due to the tonic action which 

 they exert upon the digestive tract. A few of them do contain 

 agents which aid in getting rid of worms and in this way assist in 

 keeping up the health of the animal.
