Most of the home grown coarse feeds are high in 

 Why concen- carbohydrates, low in protein, and comparatively 

 trated feeds indigestible. Nearly all of the concentrated feeds 

 are fed. are very digestible and a large number are high in 



protein, and low to medium in carbohydrates. The 

 concentrated feeds are fed with the home grown coarse feeds there-

 amount of protein in the daily ration. 



Among the most economical concentrated feeds 



Economical high in protein may be mentioned cottonseed meal, 



feeds. corn gluten meal, gluten feed, dried brewers grains, 



malt sprouts, and fine flour middlings with i8 to 20 



per cent of protein. 



Wheat bran and mixed feed contain only 13 per 

 Expensive cent of digestible protein, and 35 to 40 per cent of 



feeds. indigestible matter. The long distance transporta- 



tion of substances containing such a large amount 

 of inert material, is an important factor in making the nutrients they 

 contain relatively expensive. While they are safe to feed and are 

 most excellent for diluting or " lightening up " the more concentrated 

 by-products, it is believed that farmers often feed them in excess to 

 their pecuniary disadvantage. For milkmen they often furnish a 

 partial and cheap substitute for hay, when the latter is expensive. 

 The above remarks apply to New England conditions, as these prod- 

 ucts are undoubtedly among the very cheapest feeds for Western 

 farmers. Linseed meal while a desirable milk producing feed, is as 

 a rule an expensive one. It is not economical for the average far- 

 mer to /?/r^//(?.$'^ corn meal for milk production; it should be grown 

 upon the farm. Milk producers who are obliged to purchase all of 

 their feed, can on the contrary often feed grain mixtures containing 

 one-third corn or hominy meal to advantage. Among other expensive 

 concentrates may be mentioned oat feeds, and the various mixtures 

 containing considerable quantities of oat offal. For obvious reasons 

 it is generally decidedly more economical for farmer to make their 

 own mixtures.
