It will be seen that the cows received the same basal ration 

 daily, and in addition averaged 3.5 pounds of gluten feed or 

 dairy cake. 



Average Dry Matter and Digestible Organic Nutrients in Daily Ration 



{T'otmds). 



The two rations furnished the same quantity of total dry 

 matter daily. The Bibby's dairy cake ration contained 

 rather less protein and al)out three-fourths of a })oiind less 

 total digestible matter. This was due principally to the fact 

 that Bilibv's dairv cake was less digestible than the o-luten 

 feed. It would naturally Ije expected that Bibby's dairy 

 cake ration Avould produce rather less milk, or cause the 

 animals to shrink somewhat in live weight. 



The yields obtained from the two rations, covering a 

 period of twenty-one days in each case, were practically 

 identical. If the periods had covered twice the length of 

 time, the results would have been regarded as more satis- 

 factory. Longer periods were not ])ractical)le, owing to the 

 condition of the animals and the nearness of summer weather.
