PREVENTION OF DISEASE. 293 



Another point which has a beneficial influence on the health 

 of the animal is the kind of feed fed. Some feed stuffs seem 

 to be very influential in keeping the digestive system in 

 good order. Others have the opposite effect. 



Among the various feed stuffs which are not conducive 

 to the best health of the animals may be mentioned corn. 

 Still, corn is used in many instances as the sole grain ration 

 or almost the sole grain ration for swine. A variety of 

 feeds is claimed to be very beneficial in this respect. Oil 

 meal, roots, forage crops, shorts, skim-milk and other such 

 feeds are all supposed to have a favorable influence upon 

 the digestive system, thus are beneficial in keeping the ani- 

 mals in good health. 



Another important point from a health standpoint is 

 exercise. Where swine are confined in small, damp, filthy 

 yards it is next to impossible to prevent disease. The sur- 

 roundings are just right and if disease should come in the 

 neighborhood it makes an excellent place for it to start. 

 Swine are not unlike people in many respects. Some people, 

 especially those who are in good health, are oftentimes ex- 

 posed to typhoid fever and other germ diseases without 

 danger. On the other hand, other people who are not in 

 good health when exposed to any such disease are very 

 susceptible to the same. The same thing is true in the case 

 of swine. 



Another important point which will be found to be very 

 helpful in case disease should break out in the flock is that 

 of having the hogs scattered over the farm. By so doing 

 disease may break out in one place and the remainder of the 

 hogs on the farm may not be affected at all. On the other 

 hand, if they are bunched up in small yards and disease 

 should break out, in many instances the entire flock will be 

 affected before it is noticed. In such an instance the only 

 thing to do is to separate the hogs as soon as the disease is 

 noticed, disinfect all thoroughly and transfer them to other 

 yards. 



Worms cause much trouble among swine. They may be 

 prevented by judicious feeding. They may be cured by many 

 of the well known worm powders which are advertised in 

 our agricultural papers. 



In introducing or purchasing new stock upon the farm 

 the greatest precaution possible should be taken else disease
