PRINCIPAL SWINE FEEDS AND THEIR USE 149 



Note particularly that while corn is superior, in that it produces 

 greater daily gains and requires the least feed for 100 pounds of 

 gain, both ground kafir corn and ground milo maize and even f eter- 

 ita rank up closely. Some other tests in Kansas indicate that 

 ground kafir corn and milo show up favorably in comparison with 

 corn, but that sweet sorghum feed is, to quote the authors, "decid- 

 edly inferior to the other grains. " "The other grains," of course, 

 refers to ground corn, kafir corn and milo maize. In concluding 

 the dry-land grain topic, it is well to bear in. mind that the dry- 

 land sorghums are a god-send to the dry-land farming country in 

 our central western states, and that they are particularly valuable 

 as an adjunct feed in the alfalfa sections situated within or close to 

 the dry-land sorghum country. 



Hominy Feed. Hominy is a by-product of corn grain manu- 

 facture. It is a residue remaining after the cornmeal or hominy 

 grits have been removed from the corn kernel. The mere fact that 

 hominy feed must be manufactured means getting a product that 

 runs relatively low in water, around 10 to 13 and once in a while 

 to 14 percent. Being a by-product of corn manufactured entirely 

 by a mechanical process, there being no solution made or chemical 

 changes inaugurated, it is an excellent substitute for corn grain. 

 There are two kinds of hominy feed one from which the fat has 

 been partially extracted, and the other in which it is left with the 

 germs. Hominy feed itself really comprises the bran, the germ and 

 the floury white starchy portions, the hard flinty parts of the ker- 

 nel being used for hominy grits or cornmeal. If the germs are fat 

 extracted, this means that when the germs are replaced there is 

 much less fat added to the hominy feed as it comes to the farm than 

 where the fat is not extracted, there being a difference of some 5 

 percent. In the circumstances then we should naturally believe 

 that the fat-extracted hominy feed is not so valuable as that in 

 which the fat remains, and we should make a difference of about 6 

 percent in relative values, basing our statement on the facts that 

 a pound of corn fat is worth about two and one-fourth times as 

 much as a pound of ordinary corn starches. But it is good general 

 American policy to extract the fat, inasmuch as it can be used for 

 human consumption, and the extraction of the oil from the germs 

 of corn should be encouraged. While it is true that the feed will 

 probably not be so good for swine, yet we swinemen who believe in 

 the swine business must have the patriotic viewpoint, and put Amer- 

 ica and its inhabitants first. 



A Substitute for Corn. Hominy is a good substitute for corn, 

 and requires practically the same supplements, but we find in prac- 

 tice that it takes about 20 percent less tankage to balance 100 

 pounds of hominy feed than it does to balance the same amount of 

 corn. This is presumably due to the large concentration of the 

 germs in the hominy feed, the germs furnishing some of the spe- 

 cific nutritional supplements that are present in tankage. Twenty 

 pounds of hominy feed contains practically- the same amount of
