DAIRY MEETING. 93 



man has to retest, and once in a while an animal from the sound 

 herd has to be transferred over to the diseased one. Finally, if 

 good care has been exercised to make a sharp line of division 

 between the sound and the diseased herds, if they are in separate 

 barns with separate attendants, in course of time he may have a 

 sound herd. 



The objections are very evident. The man has to maintain 

 two herds, in two barns, with two corps of attendants to make 

 this method thoroughly satisfactory ; he has to sterilize the milk, 

 and these animals are not as productive as healthy aJiimals. It 

 costs money to keep animals anyway, and the best and soundest 

 are none too good. In this country this method has not been 

 found very practicable. In the State of Pennsylvania, where 

 the State laws allow the use of this method, and the option is 

 always given the owner of the herd whether he shall have his 

 herd cleaned up at once or retain the diseased animals, the 

 report of the authorities is that the Bang method is seldom used. 

 One herd in the State of Maine is being treated in this way at 

 the present time, but the conditions are exceptional where a man 

 has another uninfected barn somewhat removed from the gen- 

 eral herd barn and a man who can take care of these animals and 

 not go near the sound animals, and where he can sterilize his 

 milk and use it profitably. It is not a common method but it 

 certainly ought to be allowable, and under some conditions it 

 may be wise to follow it. 



The other method is known as the slaughtering method. That 

 is rather a harsh way of putting it, but that is about what it is. 

 We simply kill and make phosphate of or bury the diseased ani- 

 mals, disinfect the barns and have a sound herd from the start. 

 But the slaughtering is only a part of it. We have 

 slaughtered the animals, but we want to continue in 

 the dairy business. What are we going to do? ^^'e 

 do not want to burn down our barns and build new ones ; 

 we want more cows and have to keep them in the same old barns. 

 It is just as important that we disinfect our barns as that we get 

 the diseased cattle out. In getting the cattle out we do not 

 accomplish anything, in a sense, in the protection of other ani- 

 mals. The tubercle bacilli remain in the barns. If we have got 

 rid of the cattle we have left the germs and if we put new cattle
