Corn Substitutes for Growing Pigs

Potatoes. 



When potatoes are extremely cheap, they may be fed 

 profitably to fattening pigs if cooked and properly supple- 

 mented. Potatoes are one of the feeds which require 

 cooking. Raw potatoes are not eaten with relish and 

 fail to maintain pigs when given alone.^ The necessity 

 of feeding some nitrogenous supplement is shown by the 

 fact that potatoes contain a smaller proportion of pro- 

 tein than corn. 



The value of cooked potatoes for finishing well-grown 

 shotes in the dry lot is indicated by the results of two 

 experiments conducted at the Wisconsin Experiment 

 Station by Henry .^ In each trial corn-meal alone was 

 fed to one group of pigs, and a mixture of 1 part corn- 

 meal and 3 parts cooked potatoes to a second similar group. 

 A minimum of water was used in cooking the potatoes so 

 that none of the liquid was lost. The weight of the 

 cooked potatoes with liquid just equaled that of the raw 

 potatoes. The averaged results of these two experi- 

 ments are shown in Table CLVII.
