FIFTY-SECOND ANNUAL CONVENTION 173 



and when you grind that corn grind it down to the finest 

 sort of a meal. 



200 pounds of wheat bran. 



Pour on top of that 100 pounds of cottonseed meal, 

 then put the whole thing together. Then take that mix- 

 ture and feed one pound of it for each three to four pounds 

 of milk the cow gives in a day, give her all the hay and sil- 

 age she will eat and this grain mixture I have just sug- 

 gested, make her comfortable in the barn, curry her, keep 

 her clean, make her at peace and happy in the world, 

 plenty of water, treat her kindly, milk her regularly, and 

 if you started out with a good cow you will have a profit- 

 able cow, there is no doubt about that. 



There is just one other phase of feeding I want to 

 mention then I am going to give way to Mr. Barney. That 

 is in regard to what is known as the vitafnine D in the feed- 

 ing of dairy cows. Now vitamine D, as you heard yester- 

 day from Professor Morrison, is really a point of new dis- 

 covery, a point that has not been definitely determined. I 

 will mention a point that has not been definitely proven, 

 but I am giving it to you for what it is worth as a sug- 

 gestion. 



You take up in northern Illinois and southern Wiscon- 

 sin, there you will find most dairymen put their cows in 

 the barn as soon as the weather begins to get cool in the 

 fall, put drinking fountains in front of the cows, and do 

 all these things in quite a thorough way, as I have sug- 

 gested, then along about this season of the year or a little 

 later they begin to lose lots of calves through abortion. 

 Lots and lots of farmers lose their calves from what they 

 term contagious abortion. Investigators on this subject are 

 beginning to tell us more and more that it may be caused 

 due to the method of feeding, and I am giving you this not 

 as a final statement on it but for consideration, and in order 

 for me to prove this point or to present it before you in the 

 best way, I must go back and bring up a little more evi- 

 dence on another line, and that is at the University of 

 Wisconsin they took chickens and put six birds and a 

 .cockerel in a coop, and they reproduced that experiment
