The three samples averaged 15.23 per cent protein and contained but 

 Httle fiber ; a sample tested several years since proved to be 82 per 

 cent digestible. It was worth the price asked, $1.15 a hundred 

 pounds. 



Rye bran, is not as bulky as wheat bran and would be considered 

 rather more of a starchy than a protein feed. The price, — $1.15 

 a hundred — was reasonable, but the rye feed would be considered 

 more economical. 



Oat middlings, an entirely different product from oat feed, averaged 

 17.84 per cent protein and 7.08 per cent fat. It should be fully equal 

 to fine wheat middlings in feeding and economic value. 



Alma dried molasscs-bcet-piilp as its name implies. 

 Sugar beet consists principally of sugar beet pulp, to which has 

 by-products. been added beet molasses and the mixture thoroughly 

 dried. It is a starchy feed and is not economical as 

 a source of protein, containing only from 7 to 9 per cent. The 

 sample examined had some 25 per cent of water solubie material 

 (molasses) and had at least two-thirdsof the feeding value of corn meal. 

 This department is now testing its feeding value. 



Sugar beet-pulp, also being offered, is the wet residue from the beet 

 factories. It contains 90-92 per cent water, has a feeding value of 

 about $2.00 a ton delivered on i/ie /arm,^x\A can be fed to advantage 

 only by nearby residents of beet factories. 



F. WHAT CONCENTRATES SHALL THE FARMER 



PURCHASE? 



Concentrates do not permanently affect the percent- 

 Quality of age composition of the milk. Feeds having a high 

 milk not fat percentage, such as cottonseed meal and distil- 

 changed by lers' dried grains may temporarily increase the fat 

 concentrates, and cream percentage, but the milk shortly returns 

 to its normal composition. The richness of the milk 

 in fat depends primarily on the breed and individuality of the cow 

 and also upon the stage of lactation. The only way to make more 

 cream and more butter is to make more milk.
