Dried beet pulp can more properly be classed as a roughage. Its feeding 

 value appears to be greater than its chemical composition would indicate, at 

 least in the opinion of many feeders, especially where cows are receiving 

 heavy grain rations on advanced registry tests. Its beneficial effect is due 

 probably not only to the nutriment which it contains, but also to its favorable 

 influence upon the general condition of the animal. 



The samples guaranteed to contain an admixture of beet molasses did not 

 vary greatly in composition from the plain beet pulp. 



Oat feed is the by-product from the milling of rolled oats, and is used ex- 

 tensively as a component of mixed feeds. Its feeding value is about the same 

 as that of a good quality of mixed hay. 



Prepared Feeds. 



The prepared feeds found on the Massachusetts market may be divided 

 into two general groups. The first group contains one or more low-grade 

 products mixed with high-grade feedstuffs in order to make the former ma- 

 terial more salable and usually at a higher price. The second group contains 

 no filler, such as oat hulls, grain screenings, cottonseed hulls and the like. 

 The tabulation of analyses does not follow this classification. 



Cottonseed feed is a mixture of ground cottonseed hulls with some 

 cottonseed meal. The only excuse for the offering of such a mixture in the 

 north is to sell the hulls to better advantage. Cottonseed hulls should be 

 used as a cheap roughage where produced and not shipped long distances, 

 otherwise the cost of the nutrients they contain will be still further increased 

 by the high freight charges. Four brands were collected and analyzed. 



Wheat and Rye Mixtures. — Such mixtures were found on the markets 

 to a considerable extent during the war, when they were used as substitutes 

 for the wheat products, the supply of which was greatly curtailed. They 

 are practically equal to the straight wheat by-products in feeding value. 

 Two brands only were collected, which would indicate a decreasing demand 

 on account of the normal output of wheat -products. 



Dairy Feeds. — Such feeds are intended as complete grain rations for 

 milk production. A wide variety of material is used, some of which is not 

 available to the feeder for home-mixing. It does not follow, however, that 

 fully as satisfactory rations cannot be mixed from feeds available in local 

 stores. Many of the dairy feeds contained nothing but excellent material; 

 others contained a considerable amount of filler, such as grain screenings, 

 oat hulls or clipped oat refuse. A number contained alfalfa. While alfalfa 

 is an excellent roughage, as a component of dairy feeds it must be considered
