FORTY-THIRD ANNUAL CONVENTION 167 



Q : How much buttermilk do you give them ? 



A : We can get them to drink 30 pounds of buttermilk a" 

 100 pounds. I think that is too much. 



Q : What do you consider right ? 



A : Ten pounds. 



O: Can you tell us something about the construction of 

 your milk feeder? 



A: We bought the first one; now we make them one bet- 

 ter. We make a trough — we have a higher board than they have 

 got; then we have another trough which we make with a 2x4. 



Q : What do you figure the value of skimmilk over butter- 

 milk? 



A: Not having fed it, I cannot say from experience, but 

 it should be worth at least 10 per cent more. 



Q : What would be the difference where the milk had been 

 pasteurized and where not pasteurized? 



A: In the unpasteurized buttermilk, of course, the casein 

 is in its natural state. The casein is really the only part of it 

 which has feeding value. 



Q : Would it not be more desirable to feed them the skim- 

 milk from pasteurized milk on account of tuberculosis? 



A: I don't think so. 



Q : What did you mean by double vaccination ? 



A : Giving them the virus and serum treatment. In sim- 

 ply giving them the serum treatment it might do in a case where 

 you just wanted to get by for about sixty days where you did 

 not have cholera, but it leaves no immunity with the hr>o- wi;h a 

 jingle treatment. There is only one way to get perfect immu- 

 nity and that is to give them the virus which is the stuff that 

 gives them the cholera, and then give them the serum to counter- 

 act the virus.
