Gluten meal, likewise a very digestible protein concentrate (31.5 

 per cent, digestible protein) ranks with linseed meal in nutritive 

 value. Two to three pounds daily is the usual amount to be fed, 

 mixed with more bulky feeds containing less protein. 



Distillers'' dried grains, the kiln dried residue from the manufac- 

 ture of alcohol, spirits and whiskey from the several cereals, is also 

 an economical protein feed. It has the advantage of being bulky, 

 and ranks quite closely in feeding value to gluten feed. 



Gluten feed is a mixture of gluten meal, corn hulls and broken 

 corn germs. The feed has a high digestibility, and contains 22 per 

 cent, of digestible protein. It is considered one of the very best 

 feeds for milk production, and at the market prices usually prevail- 

 ing, is almost always an economical concentrate. Three to four 

 pounds (2^ to 3^ quarts) can be fed daily mixed with bran, malt 

 sprouts or other bulky feeds. 



Ala It sprouts are not palatable, and when used should always be in a 

 grain mixture. They are quite bulky, and will serve as a satisfactory 

 diluter of the heavier concentrates. They may be fed dry as one-quar- 

 ter of the daily grain ration, and at ordinary market prices may be re- 

 garded as an economical feed. They absorb large quantities of 

 water, and should always be thoroughly moistened if over two pounds 

 are fed daily. 



Wheat l>y-products — middlings, mixed feed and bran — are among 

 the most popular feeds offered. 



Fine or flour 7niddliugs possess about 25 percent, greater feeding 

 value than bran. They are quite desirable for swine and young 

 stock, and as a constituent of grain mixtures for milk production. 

 The Station has had good results by feeding milch cows equal parts 

 by weight of flour middlings and distillers' dried grains. 



Mixed feed — bran and middlings — varies noticeably in both feed- 

 ing and commercial value. The larger the quantity of fine middlings 

 present, the more valuable the feed. Some so-called mixed feed 

 contains scarcely any middlings. The best grades are probably 

 worth about one dollar a ton more than bran. If such a feed is pre- 

 ferred, the dairyman may often find it to his advantage to purchase 

 the bran and fiour middlings separately and mix by weight three 

 parts of bran and one part of middlings.
