CHAPTER IX 



Feeds and Feedins 



The problem of securing large and economical 

 gains in the feeding of live stock is not entirely 

 one of food supply, although this is the factor 

 which can be most definitely controlled and upon 

 which we have the most reliable information. The 

 other factor is the individuality of the animals 

 themselves. Two animals alike as to external ap- 

 pearance, of equal age and equal weight, when 

 placed under exactly the same conditions and given 

 exactly similar feed, will generally not make equal 

 gains, because of the inherent ability of the one to 

 utilize its feed to better advantage than the other. 

 The general question of feeds, however, as to kind, 

 amount and methods of feeding for securing any 

 desired result with any one class of live stock, has 

 received greater attention at the hands of investi- 

 gators and experimenters than probably any other 

 single phase of agricultural science. 



PRINCIPLES OF FEEDING 



We have a vast amount of reliable information 

 bearing upon the composition of feeds under all 

 conditions and the effect of these feeds used in 

 varying proportions in securing a desired result in 

 live stock feeding. It is not the purpose of this 

 work to enter into extended discussion of all the 

 problems pertaining to live stock feeding — ^to even 

 touch upon each of the various phases of this sub- 

 ject would require a volume in itself. Much of
