Thirty-fourth Annual Convention. ^^^ 



tnrough which the air strains before entering tlie cow's udder, 

 so no germs from the air will penetrate the udder; then, by 

 boiling the tube ten or fifteen minutes before insei^ting and keep- 

 ing it sterilized by 5 per cent solution or something of that kind, 

 there is no trouble whatever in regard to injuring the udder. 



Mr. Janes : — Did you bring up the question of calf feeders 

 at all? 



Mr. Van Pelt : — What is your experience with calf feeders ? 



Mr. Janes : — I related our experience pretty fully last year. 

 Our experience has been very satisfactory with them with young 

 calves, and I would not think of raising calves without the calf 

 feeders, at least for the first six weeks. 



Mr. Van Pelt: — Don't you think there needs to be a great 

 deal of care and attention paid to calf feeders to keep them clean ? 



Mr. Janes : — There certainly does, the same as anything 

 else one uses. 



The Chairman : — I am sorry we have not time for more 

 questions. I hope Professor Van Pelt will be with us during 

 the remainder of the sessions so that you can go to him personal- 

 ly for any information you desire. 



We will now take up the next subject on the program, 

 which will be discussed by Dr. H. R. Ryder of Chicago. I 

 know of no more important point in dairying that the health of 

 the dairy cow or health and sanitary condition nf the milk, and 

 we will now listen to Dr. Ryder on this subject. 



DAIRY CATTLE FROM A HEALTH STANDPOINT. 



Dr. H. R. Ryder, Chicago. 



Mr. President, Ladies and Gentlemen : — 



We heard this afternoon how to develop the cow and how 

 to develop the machine for making milk, we have also heard 

 how to feed her and now I come to warn you not to overdo it. 

 Of course we want to develop and want to feed, but if you overdo 

 these things you will get into other trouble, so I take up this 

 afternoon a short paper on diseases of the udder and if you will 

 permit me I will read the article and if you desire to ask any 

 questions I will be glad to do what I can to answer them.
