These figures show a slight increase in percentage of digestibility- 

 due to grinding. 



Corn and Cob Meal vs. Ear Corn for Hogs. From results at the 

 New Hampshire Station**, it was concluded that ground corn and cob 

 meal had a slightly better feeding value in increasing the daily gain 

 of hogs, but for practical purposes it is more economical to feed corn 

 on the ear rather than hauling to the mill and grinding for feed. In 

 any event, corn and cob meal is rather bulky. 



THE FEEDING VALUE OF THE BY-PRODUCTS OF CORN 



Supplemental foods high in protein are often used quite largely in 

 the production of milk and pork. The by-products of corn are increas 

 ing in amount each year because of the demand for manufactured 

 foods made from corn. These by-products are not as palatable as 

 might be supposed considering the palatability of corn itself. 



In any case the choice of protein foods depends upon their real 

 efficiency at the current market price. This efficiency depends upon 

 their total protein content together with its digestibility. Palatability 

 is a minor factor because such small amounts are fed.

Gluten Meal. Gluten meal as a pure product is now little 

 known on the market. Consisting largely of gluten it is very rich in 

 protein, reaching almost 30 per cent. Having very little foundation 

 of indigestible material, care must be exercised in its feeding.
