1 Corn gorm meal and ground corn fed mixed together in self-feeder. 

 1 Corn germ meal and tankage fed mixed together in self-feeder. 

 ' Corn germ meal and tankage fed mixed as a slop. 



From the results of the fourth find seventh lots of both the first and second 

 trials it appears that hogs <lo not make suitable gains when corn germ meal is 

 fed as a sole ration, although a number of feeders follow this practice and firms 

 selling these products advocate it. The dry starch corn gorm meal proved so 

 unpalatable that the animals would scarcely eat a maintenance ration. When 

 the hogs had free choice of starch corn germ moid and ground corn (trial 1, 

 lot .">), they made practically all their gains on corn. When compelled to eat 

 the starch meal because it was mixed with corn 1:1 and 1:3 (trial 2, lots 5 

 and 6) they made nearly twice the gain on the more liberal corn ration. < >n 

 the other hand, hominy corn germ meal and corn mixed .3:1 (trial 2, lot 10) 

 was relished, and caused an increase of 0.25 lb. in daily gain per head over 

 the lot receiving hominy corn germ meal alone (trial 2, lot 7), but not as rapid 

 or as economical gains as the check lot (lot 9). 



The results of lot of trial 1 show that starch corn germ meal is not a satis- 

 factory substitute for corn when supplemented with tankage. Five lots were 

 fed with rations In which the corn genu meals were used as partial substitutes 

 for tankage with ground corn as the basal ration. Lot 1 of the second trial 

 made very rapid gains, but produced pork at a considerably greater expend i ture 

 of feed than the check-lot. In the third trial when mixtures of starch corn 

 germ meal and tankage either dry or in slop were fed (lots 1, 2, and 0) daily 

 gains and economy of production are in each case less than In lot 0, which re- 

 ceived tankage as sole supplement. In lot 3, trial 3, hominy corn germ meal 

 satisfactorily furnished 75 per cent of the supplement. 



4. Palmo Midds. — A lot of hogs in I lie third trial fed Palmo Midds in addition 

 to the basal ration of ground corn and tankage, gained 15.7 per cent more 

 rapidly than a lot fed standard wheat middlings in addition to the basal ration, 

 and required 9.5 per cent more feed per pound of gain. The percentage of crude 

 fat in the Palmo Midds was over twice that of the middlings. 



5. Commercial mixed hoy feeds. — Two commercial mixed hog feeds did not 

 produce pork as rapidly or as economically as a ration consisting of ground 

 corn and tankage.
