all possible the animals should receive succulent food in the 

 shape of roots in addition to the grain, which grain should 

 not consist entirely of corn. 



The breeding hogs and the fat hogs may run together until 



three months of age, 

 when the breeding ani- 

 mals should be taken 

 out. At this age the 

 sows will begin to show 

 up, so that those likely 

 to make the best an- 

 imals may be chosen 

 for breeding. If later 

 on some of the sows not 

 chosen should show good 

 form, they too may be 

 taken out of the fat 

 herd. Those animals 

 chosen for breeding 

 should be fed a nitrog- 

 enous ration. In addi- 

 tion, they should be permitted to take abundance of exercise. 

 If they are confined too closely and fed a fattening ration, their 

 breeding powers are likely to be weakened.
