THE SELECTION OF FOODS 6l 



Feed corn only as the concentrate to horses and over- 

 much fat will be produced at the expense of energy. Feed 

 bran to young pigs before and after weaning, and they will 

 not thrive upon it, but feed the same in large proportion 

 to a brood sow and it will help to nourish her pigs in the 

 milk that it will furnish. Feed all bran as the concentrate 

 to a milch cow and it will greatly stimulate the milk flow, 

 but at the expense of flesh. Feed only corn and the cow will 

 gain flesh at the expense of milk. Feed both bran and corn 

 and the result will be a fair amount of milk with no loss 

 of .flesh. 



The manurial value of some foods is so great, that in 

 some instances and under some conditions, it approximates 

 more or less the value of the same for feeding. Such are 

 bran, oil cake and cottonseed meal. The relation of these 

 values will depend, first, on the price of the foods ; second, 

 on the cost of commercial fertilizers; and third, on the 

 necessity for using them. The lower the cost of the food, 

 the dearer the cost of the commercial fertilizer and the 

 greater the necessity for applying the added fertilizer, the 

 more nearly will the manurial value of the food approximate 

 the feeding value. In feeding concentrated foods and in 

 some instances fodders, especially legumes, this question is 

 sufficiently important to merit the most careful considera- 

 tion when selecting or providing them.
