cent, of fat, no rancid odor or taste was noticed after the 

 meal had been in the barn six months. Its mechanical con- 

 dition was all that could be desired. The objection to feed- 

 ing by-products especially rich in fat is that, if they are fed 

 alone in large quantities (above 3 quarts daily) or fed in 

 combination with other material of a similar nature, the ten- 

 dency i-> to cloy the appetite of the animal, or — in warm 

 weather especially — to produce inflammation of the milk 

 glands. 



In a daily grain ration of 9 pounds we would not advise 

 feeding over 3 or 4 pounds of but one by-product having 

 above 7 to 8 per cent, of fat. 



The principal criticism on this experiment would natu- 

 rally be the shortness of its feeding- periods. This could not 

 have been well avoided. The results obtained, however, are, 

 it is believed, sufficient to give one an idea of the compara- 

 tive value of the two grains.
