Hoiv to Use the Key. 



It is not possible in this connection to show the relative effects of 

 the various feed-stuffs on the flow of rnxW or the production of beef. 

 The figures are offered rather as a Icey to the comparative commer- 

 cial values of the different feeds based on the digestible nutrients 

 contained in them. Thus if wheat bran is worth 86, cottonseed 

 meal would be woith 152. These figures can be easily converted 

 into dollars. Thus if corn meal is worth $20.00 per ton or loo, 

 wheat bran would be worth 86 per cent of $20.00 or $17.20 the 

 amount the farmer can afford to pay for the bran. Again with cot- 

 tonseed meal worth $25, what can the farmer afi^ord to pay for old 

 process linseed meal ? Cottonseed meal equals 152, or $25, and 

 linseed meal 138. We have a case in simple proportion. 

 152 : 138 : : $25 : x=$2 2.7o, the value of a ton of linseed meal. 

 It must not be forgotten that these figures do not take into consid- 

 eration the mechanical condition, or the particularly favorable effect 

 which some feeds are supposed to exert upon the general health of 

 the animal.
