One dollar would buy 12.2 pounds of protein in the 

 36 per cent, cottonseed meals and 14.5 pounds in the 43 

 per cent, cottonseed meals. Or in other words one dollar 

 would buy over eighteen per cent, n^ore protein in the US 

 per cent, cottonseed meal than in the 36 per cent, meals. 

 The average price per ton of the higher analysis meals is 

 higher but the cost per pound of protein is less. Determine 

 the comparative value of the feeds offered for sale before 

 purchasing. Buy intelligently! 



READY MIXED FEEDS SHOULD BE PROPERLY 



BALANCED. 



In selecting a ready mixed feed such as a dairy feed 

 it is well to examine the analysis and see that the feed is 

 properly balanced for use with the kind of roughage which 

 you feed. The Dairy Department of the University of 

 New Hampshire recommend for use with a high protein 

 roughage a feed containing 15 per cent, crude digestible 

 protein, for use with a medium protein roughage a feed 

 containing 17 per cent, crude digestible protein, and for use 

 with a low protein roughage a feed containing 19 per cent, 

 crude digestible protein. The analysis of a feeding-stuff 

 shows the crude protein of which a portion is not diges- 

 tible. While it is impossible to give an accurate figure for 

 the digestiblity of ready mixed feeds it will be approxi- 

 mate to assume that from 80 to 85 per cent, of the crude 

 protein is digestible. On such a basis for use with a high 

 protein roughage a ready mixed dairy feed should contain 

 at least 17.5 per cent, protein with a medium protein rough- 

 age at least 20.00 per cent, protein and with a low protein 

 roughage at least 22.00 per cent, protein. 



IMPORTANCE OF ALFALFA AND CLOVER 



Recent studies in animal nutrition and feeding trials 

 have led to discoveries which have a very important bear- 

 ing upon practical feeding. It has been shown for instance
