3. The clovers and alfalfa should be cut in early bloom. If cut in 

 late bloom their nutritive value is noticeably lessened. 



4. Concentrated feeds, aside from their palatability, should be pur- 

 chased for their high digestibility or net energy value and protein con- 

 tent. 



5. The cereals have a high net energy value; cottonseed meal, glu- 

 ten feed, distillers' dried grains and flour middlings, while they are 

 highly digestible (high net energy value) are purchased as a rule be- 

 cause 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 farm is the carbohydrate factory. As a rule, it is not prac- 

 ticable 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, as a rule, 

 is not good economy.
