5- At the present prices of grain a ready ration meeting the 

 above demands should not cost over $26 to ^27 a ton, or $1.3010 

 $1.35 a hundred pounds.' 



There are at best very few proprietary mixtures that fulfil the 

 above requirements. The station is at present making a study of 

 ready rations in order to ascertain more exactly their value as com- 

 pared with those that may be prepared by the farmer. 



That the several home mixed rations which precede, prepared from 

 standard concentrates, meet the requirements as above outlined may 

 be demonstrated by the following tabulation : 



The table shows : That a pound of the several mixtures measures 

 from 1 to 1.3 quarts, averaging 1.2 quarts ; that the rations contain 

 from 20.4 to 26.3 per cent or pounds of total protein in 100, averag- 

 ing 22.5 per cent, and that this protein is from 78 to 84 per cent 

 digestible, averaging 80.5 per cent : that the rations contain from 

 16 to 20 per cent of digestible protein, averaging 18 per cent ; that 

 the rations average 69 pounds of digestible organic matter in 100, 

 and 7.6 per cent of total fiber ; that a ton of the mixtures costs from 

 $24.86 to $27.42, averaging $26.04. 



' Prices of some concentrates have advanced since the above calculations were made. 

 The difference, however, would not be marked.
