340 Pork Prodtiction 



It would appear from these results that growing and 

 fattening pigs, up to a weight of about 150 pounds, do 

 as well on unground as on ground corn. Pigs during the 

 last three months of their market preparation, however, 

 seem to gain faster and more economically on ground 

 corn than on either ear or shelled corn. A study of the 

 detailed results by successive months of these experi- 

 ments shows that the heavier and fatter the pigs be- 

 come, the greater is the advantage of grinding. This 

 rule is also suggested and largely confirmed by the results 

 of the Iowa experiments. 



General conclusions. 



The following general conclusions appear to be justified 

 by all the experimental results considered : 



1. There is no advantage in feeding dry shelled corn 

 over ear-corn, so far as rate and economy of gains are 

 concerned. 



2. Pigs receiving shelled corn soaked twelve hours 

 make faster gains with slightly less feed than do pigs 

 fed ear-corn. This is particularly true for older pigs 

 during the latter months of fattening and when they are 

 on grass or forage crops. 



3. Ear-corn or dry shelled corn will, as a rule, give as 

 rapid and more economical gains with pigs weighing less 

 than 150 pounds as will ground corn fed wet or soaked. 

 Pigs weighing from 150 pounds up to market weights, how- 

 ever, will usually gain faster with from 4 to 6 per cent less 

 feed for a unit of gain, when on ground corn fed wet or 

 soaked than when on ear or dry shelled corn. 



4. When corn is ground, it should be wet or soaked 

 before feeding. Dry corn-meal does not seem to be 

 relished, especially by young pigs.
