662 FEEDS AND FEEDING 



pared with tankage as a supplement to corn or milk, 100 Ibs. of peanut 

 feed has been worth as much as 46 Ibs. grain plus 37 Ibs. tankage. As 

 will be noted, this is much lower than the value of peanut meal from 

 hulled nuts, given in the preceding paragraph. 



980. Gluten feed; corn germ meal. But little corn gluten feed is fed 

 to swine, for it is much more valuable for cattle than for hogs. (210) 

 Not only is it a rather bulky feed, but also the protein it supplies is not 

 well suited to balance the proteins of the cereal grains. (937-8) Further- 

 more, it is not very palatable to swine. In trials by Eward at the Iowa 

 Station 106 adding gluten feed to a ration of corn and tankage, for pigs 

 either in dry lot or on pasture, did not prove economical with feeds at 

 usual prices. Similar results were secured by Loeffel at the Nebraska 

 Station 107 when gluten feed was added to a ration of corn, tankage, and 

 alfalfa hay, fed to fattening pigs in dry lot. Also in a trial by Ashby at 

 the Minnesota Station, 108 it was not profitable to add gluten feed to a 

 ration of corn feed meal, shorts, and tankage. Fed as the only supple- 

 ment to corn, gluten feed has not given good results either in dry lot 

 feeding or with pigs on pasture. 109 



Corn germ meal (also called corn oil cake meal or germ oil meal), is 

 the by-product left after most of the corn oil is pressed from corn germs. 

 (212) It contains only about one-third as much crude protein as tank- 

 age. Several trials 110 to study the value of corn germ meal have been 

 carried on by Eward at the Iowa Station, Robison at the Ohio Station, 

 and Skinner and Starr at the Indiana Station. These trials show that 

 this feed should be fed as a partial substitute for tankage or dairy by- 

 products, for it gives good results when thus used. On the other hand, 

 poor returns are usually secured when it is fed as the only supplement 

 to corn for pigs in dry lot. "When fed with grain as the only supplement 

 to pigs on good pasture the gains are quite satisfactory, but corn germ 

 meal, thus fed, has been worth little or no more than corn, ton for ton. 

 During the "World "War when corn germ meal w'as sometimes lower in 

 price per ton than corn, it was occasionally used as a substitute for that 

 grain in swine feeding, but, thus used, it has not been equal to corn in 

 feeding value. Skinner and Starr found corn germ meal resulting from 

 hominy manufacture better than that secured as a by-product from starch 

 plants. When fed in too large amounts, corn germ meal may cause 

 scours, and it is often unpalatable to pigs. 



Eward has found that when pigs on pasture are self-fed, free choice, 

 corn and also a mixture of corn germ meal and tankage, the gains are 

 somewhat more rapid than if tankage is used as the only supplement to
