PRINCIPAL SWINE FEEDS AND THEIR USE

standpoint of average daily gains made but also from the stand- 

 point of least grain required for 100 pounds of gain. If the corn 

 must be prepared rather than grind or grind it and soak it, it is 

 better simply to shell it and soak it. 



What will happen with pigs of a little larger weight? Some 

 100-pound shotes were fed 140 days from early spring to the 

 middle of the summer. They had a final weight of about 290 

 pounds. Their ration was 92 percent corn grain and 8 percent 

 meatmeal tankage, this being allowed in drylot. The following 

 table shows that as igs grow older they get greater relative benefit 

 from the more elaborate preparations: 



But here again we notice that if the corn is to be prepared soak- 

 ing is a fine way to prepare the shelled corn, although the results 

 are close in all instances. One can study these figures and suit him- 

 self as to best methods of procedure. 



Let us figure out what happens to still larger hogs hogs 

 weighing about 200 pounds at the start and fed 84 days to a 

 final weight of about 360 pounds. The ration was corn grain 

 91 percent and meatmeal tankage 9 percent, fed in spring and 

 summer dry yards. The table showing the results of four different 

 corn preparations the same preparations fed to younger swine 

 above follows : 



Now we notice that as swine get older, and heavier, and more 

 mature, the dry ear corn can be shelled and soaked to advantage, 

 and, further, that soaking and shelling are as advantageous, gen- 

 erally speaking, as was the grinding or grinding and soaking. 



What happens to still more mature hogs, such as old sows weigh- 

 ing about 200 pounds and fed to a final weight of 335 pounds, on 

 the ratio of corn grain 93.3 percent and meatmeal tankage 6.7 per- 

 cent in fall dry yards for 59 days ? The answer follows :
