Corn Svbstitutes for Growing Pigs 329 



When a well-balanced ration was compared with one 

 of corn alone with stock-food added, the balanced ration 

 produced 32.95 per cent faster gains, required 25.09 per 

 cent less feed to produce the same gain, and made a money 

 charge of $1.04 less for producing 100 pounds of gain 

 than the ration of corn and stock-food. 



It would appear, then, from these results that the 

 addition of a stock-food to an unbalanced ration like 

 corn alone for fattening pigs is hardly justified, even 

 under assumed conditions in which no protein feeds are 

 available. Although increasing perceptibly the rate of 

 gain, the actual money cost of a unit of gain was increased 

 27 cents for every 100 pounds. The answer given by 

 these results to the question whether it pays to feed a 

 stock-food if the pigs are already receiving a balanced 

 ration is clearly in the negative. The mere addition 

 of a stock-food to such a ration seems to have the effect 

 of reducing the rate of gain and increasing the cost. And 

 finally, when a ration of corn and stock-food, which is 

 altogether too common, is compared with a balanced 

 ration of corn and a standard protein feed, the results 

 are in wide contrast. They pointedly suggest that the 

 money spent for stock-foods would be better used if 

 invested in some good nitrogenous feed of proven worth. 

 So far as the evidence of actual experimental feeding 

 tests is concerned, therefore, there seems to be no ground 

 on which the use of condimental stock-foods for fatten- 

 ing pigs can be justified in practice.
