4. Concentrated feeds, aside from their palatability, should 

 be purchased for their high digestibility or net energy value and 

 protein content. 



0. The cereals have a high net energy value; cottonseed 

 meal, gluten feed, distillers' dried grains and flour middlings, 

 while thev are highly digestible (high net energy value) are pur- 

 chased as a rule because of their protein content. 



0. W'lieat bran is an expensive source of nutrition, but its 

 bulk and laxative qualities frequently commend its use to eastern 

 feeders in amounts not exceeding 25 to 30 per cent of the entire 

 eraui ration. 



7. Some proprietary grain mixtures are fairly economical; 

 others, which contain low-grade by-products, are quite expensive, 

 due to the fact that such feed mixtures are sold at about the same 

 prir-es as the high-grade concentrates. 



8. The farm is the carbohydrate factory. As a rule, it is not 

 practicable for the farmer or dairyman to produce all of the high- 

 grade protein feeds to supplement his home-grown carbohydrates. 

 He should endeavor to produce as much as possible of the needed 

 protein in the form of clover, alfalfa, peas and possibly soy beans. 

 In some cases he will find it necessary to purchase corn and the 

 like, but this is not advised Avhenever it can be grown upon the 

 farm.
