CHAPTER XIV 



PREPARATION OF FEEDS AND METHODS OF 

 FEEDING 



THE idea underlying the practice of grinding, shelling, 

 soaking, or cooking feed for pigs is that the special prep- 

 aration will result in improving its palatability, hence 

 increasing consumption and hastening gains, or that it 

 will insure more complete digestion, thus resulting in 

 less waste of feed and greater economy of gains. But 

 these special methods of preparation necessitate more 

 or less expense for labor, machinery, and equipment. 

 Before any method of preparation is justified, therefore, 

 it must be shown that the increased rate and economy 

 of gains which may result are sufficient to pay this extra 

 feed cost. 



CORN 



Grinding corn. 



Numerous and extensive feeding experiments in which 

 ground corn has been fed against ear and shelled corn 

 have been made at the Wisconsin, Iowa, and Indiana 

 Experiment stations. The advisability of grinding will 

 be determined by a study of these results, the Wisconsin 

 trials being considered first. 



In Table CLX appear the average results of ten years 

 of experimental work at the Wisconsin Station 1 as com-
