rather bulky and usually the corn grains are among the cheap- 

 est sources of protein. These grains are not particularly palat- 

 able, consequently they should be used with other feeds in tho 

 grain ration. 



Dried Beet Pulp. 



Digestible nutrients — Protein, 4.6 per cent; carbohydrates and fat, 

 67 per cent. 



Dried beet pulp is a by-product from the manufacture of 

 sugar from the beet. As a source of protein it is not of high 

 value, and the farmer should recognize this fact when he buys it, 

 It is bulky, however, and has an excellent physiological effec^< 

 upon the cow as it aids in keeping her digestive organs in good 

 condition. When for any reason neither silage nor roots are 

 available the pulp can be soaked for about 12 hours in about 

 four times its weight of water; it then constitutes a good substi- 

 tute for a succulent roughage. Beet pulp should be classed as v^ 

 carbohydrate rather than as a protein feed. 



Molasses. 



Digestible nutrients — Protein, 1 per cent; carbohydrates and fat, 

 58.2 per cent. 



Molasses, from both the beet and cane sugar factories, ii 

 valuable as a source of energy or heat-making material, the main, 

 difference between the two kinds being that the former is morq 

 laxative when fed in large quantities. When fed in small quan- 

 tities, molasses adds materially tO' the palatability of the ration, 

 but unless it is very low in price it is not usually an economical 

 feed for dairy cows. 



Buckwheat Middlings. 



Digestible nutrients. — Protein, 24.6 per cent; carbohydrates and fat, 

 52 per cent. 



This floury feed is composed largely of that part of the 

 buckwheat kernel under the hull together with some of the coars- 

 est of the flour. It is rather heavy and tends to produce a 

 tallowy butter if fed in large quantities. In certain sections it 

 is one of the cheap sources of protein. Frequently bran anc^
