In Table LXXIX the actual amount of concentrates 

 which would be fed in the forage and dry lot periods is 

 calculated from the above figures. The results are stated 

 in terms of shelled com and tankage, and assume that 

 the latter makes up 8 per cent of the ration, on the average.

The above table serves to , illustrate the important 

 principle that as the intensity of grain feeding increases

 tion of old to new com fed increases. In other words, 

 full rations during the summer on forage necessitate a 

 large use of old com and permit of only a minimum 

 use of the cheaper new com; while the feeding of 

 limited rations during the summer results in a minimum
