4. Concentrated feeds, aside from their palatability, should 

 be purchased for their high digestibiHty or net energy value and 

 j^rotein content. 



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

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

 while they are highly digestible (high net energy value), are 

 purchased as a rule because of their protein content. 



6. Wheat 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 

 grain 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 

 prices as the high-grade concentrates. 



8. The fann is the carbohydrate factory. As a rule, it is 

 not practicable for the farmer or dair^nnan to produce all of the 

 high-grade protein feeds to supplement his home-grown carbo- 

 hydrates. 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 whenever it 

 can be grown upon the farm.
