most likely to make a good, record. It is not the one that commences 

 big that always lasts. He has a Jersey near the end of her period of lac- 

 tation. She comes in the first of April. Her milk tests, 4.4 and has been 

 milking since last May, I think, so you see she has been milked nearly a 

 year and gives nearly 5 pounds of butter fat from Jan. 16 to Jan 23, or for 

 seven consecutive days she shows a persistent producer. 



While these records are not ccmplete, they indicate the great varia- 

 tion in cows in Illinois. I hope next year to have the records more com- 

 plete, and more interesting and convincing, so that when I appear before 

 you that I can give facts that we have found in our own State, and, not have 

 to go to Iowa or Minnesota to obtain them. 



I am glad I have had the opportunity to meet you. 



Q: — Can you feed butter fat into milk? 



A. — No sir. 



Q: — If I feed a cow all straw, tests 3 per cent, and enrich her feed in 

 corn meal, can I increase that buter fat? 



A: — I think you decrease it. If she has been fed straw she is only 

 giving a small amount of milk. You are not feeding a cow in a normal 

 way when you feed, only straw. When corn is added you will probably 

 increase the flow of milk and the test will undoubtedly become lower; 

 it will go down rather than up. 



Q: — You say you can't feed buuer fat into milk? 



A: — That is what I said. 



When I worked in Northern Minnesota, where the grass was wild and 

 cured quickly, and the cows were not giving much milk, they tested 

 more than cows in the southern part of the State where they fed plenty 

 of grain and more succulent feed. 



Q: — Does fresh milk test as high as old milk? 



A. — The nearer the end of the period of lactation the higher the 

 test. As she advances in her period of lactation the solids and butter fat 

 increase. 



Q: — How much would be the churn test, or oil test?
