PRINCIPAL SWINE FEEDS AND THEIR USE 151 



100 pounds of gain made. Figuring the meatmeal tankage as equiv- 

 alent in economic value to 2 pounds of corn, and making an equa- 

 tion of it, 100 pounds of corn equals 105.71 pounds of hominy feed. 

 Note particularly that at the end of the feeding period the hominy 

 feed began to lose out in gains, showing that a little more fibre 

 content apparently tended to retard the gains, hominy feed having 

 the same objections in this respect as barley, only to a lesser degree. 



A Test at Ames, Iowa. On rape pasture we fed pigs shelled 

 corn self -fed plus meatmeal tankage self -fed, plus salt self-fed dur- 

 ing the entire time from weaning time. about 45 pounds to 225 

 pounds in weight. Lot 2 received the same treatment except hominy 

 feed was given in place of corn to the end of the forage season, 

 and then the last week or two, just before the pigs reached 225 

 pounds, they were changed over to corn. On the corn and rape the 

 pigs took 132 days to get the desired weight, but on the hominy 

 feed 149 days. Here, again, we have a saving in time on corn. For 

 100 pounds of gain Lot 1 required of shelled corn 344.4 and meat- 

 meal tankage 37.2, a total of 381.6 pounds; whereas the hominy 

 feed-fed Lot 2 required 340.8 of hominy feed, 72.1 of shelled corn 

 and 32.9 of meatmeal tankage, a total of 445.8 pounds of feed. 

 Where hominy feed was fed it was not the equal of corn. It took 

 practically 12 percent more feed for 100 pounds of gain with hom- 

 iny feed than with corn, although less tankage was required than 

 usual in this case practically 12 percent less. By making an equa- 

 tion of these figures it is found that 100 pounds of hominy feed is 

 equal to 82.7 pounds of corn, this on the basis that 1 pound of tank- 

 age is considered equivalent to 2 pounds of corn; or, figuring it 

 differently, it took practically 121 pounds of hominy feed to equal 

 100 pounds of corn. Generally speaking, considering the experi- 

 ments in Indiana, Ohio and Iowa, one can feel that if he buys hom- 

 iny feed at a price less than that for corn, pound for pound, he is 

 not faring badly; but if he can buy hominy feed for 10 percent 

 less than corn he is doing well, and if he can buy it at 15 percent 

 less than corn it is a good buy. We must not forget that hominy 

 feed has some advantages, such as its being dry, and can be easily 

 stored. It also does not need to be ground. We are inclined to 

 think, however, that if hominy feed is wet or soaked it will give 

 somewhat better results than when fed dry but we do not have any 

 experimental evidence to back up this statement of belief. 



Emmer or Speltz. This crop is not much used. It is grown 

 some in the Dakotas and in the northern sections of -the cornbelt. 

 Emmer is not so valuable as corn or barley. The varieties of emmer 

 that have the least hull are the most desirable. Emmer, in order to 

 give the best results, should be ground, and preferably wet, and 

 better still soaked. Presumably the same supplements may be used 

 for emmer or barley as with the ordinary basal grains. 



Potatoes. Cull potatoes may sometimes be used to advan- 

 tage in swine production. Potatoes may be used as a substitute for
