ITS Kepoet of Farmers' I^'stitutes 



cannot be laid on this point. The position of the feeds in the 

 list may change from time to time, but there will always be some 

 high protein among those relatively the cheapest on the basis of 

 relative values alone, and surely if the manurial values are given 

 any consideration. This discussion again brings out sharply the 

 need for conserving the liquid manure, for the manurial values 

 arise principally from the value of the nitrogen and therefore the 

 protein. 



It might seem that the views of the writer are somewhat in 

 opposition to the views of Dr. Jordan in the first section of this 

 paper. A careful study of both parts will show that this is not 

 true. The writer has merely amplified the first point of Dr. 

 Jordan's — that the feed should be purchased not for the protein 

 principally, but for the total digestible nutrients. The writer has 

 simply tried to show that some of the high protein feeds are usually 

 among the four or five feeds in every list that will give total 

 digestible material the cheapest. 



Finally, in the opinion of the writer, high protein feeds are 

 likely to be the cheapest to buy to supplement home grown 

 grains. If all concentrates are purchased, probably at least one- 

 half should be high protein feeds.
