and wider behind. Every cow must be developed sufficient in 

 front, we must have heart and lung capacity and the circulatory" 

 and respiratory system developed, but that wedge form comes, 

 from an abnormal or unusual development of the hind parts^ 

 showing that a cow can eat a large amount of feed and carry a. 

 large udder. She is wide behind, necessarily wide and deep.. 

 That is where the maternal and the milk forming organs are,, 

 that is what makes the wedge form. The beef animal must be 

 free from that lean angular outline and present a thick, full- 

 round fleshy form. 



The President: What effect has feed in producing butter 

 fat in the milk, can you feed butter fat in the milk.^ I have na 

 doubt that there are farmers in this room who think that if they 

 will feed their cows all the corn they will eat, it will help ta- 

 make the milk rich. 



Prof. Curtiss: That is a question about which there is a. 

 wide difference of opinion, and I will say at the outset that 

 whatever increase of richness has been produced in the quality 

 of milk by feeding, has been produced rather by using feed] 

 that contains a small amount of fat than a large amount; in 

 other words, feeding fat in a large quantity does not have a, 

 tendency to produce more fat in the milk. We have found in 

 experiments at the station that the tendency was much more: 

 to increase the fat in the body rather than the fat in the milk, 

 by feeding fat-forming foods. There are some authorities who' 

 claim that it is an impossibility to change the butter fat im 

 milk. On the other hand, there are other authorities who« 

 claim that you can change the butter fat contents of milk, that 

 rich feeding makes the milk rich. We all know that variations, 

 have been developed and that that variation is very largelji; due. 

 to the feed and surroundings, A cow developed in the Jeraeyr 

 Islands gets rather scant, but rich food. The Holstein co>\«- is- 

 developed over in Holland, where they have very rank prodmrtive- 

 conditions, heavy growth of grass and two or three crops ik a. 

 year, and everything laden with moisture: the consequence is-, 

 that we have there a cow producing milk that contains a large- 

 amount of moisture, and the feed, to a large extent, is the cause-
