Pork Production 



The carrying capacity of an acre of corn as given by 

 the Iowa Experiment Station 1 is somewhat greater than 

 that estimated above, as shown in the following table : 



TABLE LXXXVII. CARRYING CAPACITY OF AN ACRE OP 

 STANDING CORN 



Average weight of pigs at the beginning, 125-150 Ib. 



In order that the pigs make satisfactory gains, they 

 must be supplied with water that is pure and easily 

 accessible. Portable sanitary watering devices are espe- 

 cially convenient when the field is not within easy distance 

 of the barn. Also, the pigs must have a comfortable 

 place to sleep in order to do well. With no protection, 

 a chilly rain in the late fall will undo a week's feeding. 

 Movable cots or temporarily constructed sheds may be 

 provided at little expense of time or labor. Although 

 a labor saver, the hogging-down method of feeding 

 requires that constant attention be given to the essentials 

 of good care and management if best results are to be 

 obtained.
