all farm animals, it is bclicvod that the agrecal)lo flavor and 

 odor do not make it worth the extra i)rice asked. 



4. In the feeding experiment, lasting twenty-one days, 

 the four cows produced practically as much milk on the 

 Bibhv's dairy cake as on the gluten feed ration ; the latter 

 ration i)r()duced a slight gain in live weight. The cost of 

 milk and Inilter was noticeably more on the Bibby's dairy 

 cake ration. The experiment indicates that the Bibby's 

 dairy cake ration furnished a sufficient quantity of digestible 

 matter to meet the requirements of the several cows. Had 

 the periods been longer, and the cows in a less advanced 

 period of lactation, it is believed the diflerenccs would have 

 been more striking. 



5. Bibb3^'s dairy cake, at prevailing market prices, is not 

 regarded as an economical concentrate ; it can be used, how- 

 ever, if desired, as the exclusive grain ration for sheep, 

 young dairy stock and milch cows. From 5 to 8 pounds 

 would be the usual daily allowance for the latter animals. 

 Its chief use should l)e as an appetizer, to be mixed in small 

 tjuantities with foods that, because of an inferior flavor, 

 would not be otherwise readily consumed. 



From the standpoint of economy, farmers will do well to 

 produce their ha}^ silage and corn meal, and to purchase 

 only those manufactured concentrates that are rich in protein, 

 such as cotton-seed meal, gluten feed, distillers' and brewers' 

 dried i>Tains, wheat middlinij^s and bran.
