 are made. 



Three experimental feeding trials with fattening pigs have been con- 

 cluded this 3'ear. The object of this work was to determine the relative 

 eflflciency of corn, barley and rye, alone and in combination, using Di- 

 gester Tankage as a i^rotein supplement, for pork production. All feeds 

 Avere fed in separate compartments of a self-feeder, the barley and rye 

 being ground in each case. The following table summarizes the results

Director R. S. Shaw, 



Dear Sir: I believe it is quite proper this year to list the projects 

 which have, according to my understanding, official approval and sanc- 

 tion. From the Adams fund, we receive aid for the following: 



The effect of disease in the cow on the milk. 



Tlie keeping qualities of butter. 



The decomposition of peat. 



Market milk investigations. 



Bovine infectious abortion. 

 Hatch and State funds are used to supjilement the Adams fund in our 

 investigations under the above projects and also for the support of neces- 

 sary tests and laboratory and field work incident and subordinate to the 

 main investigations. In addition we conduct the following investiga- 

 tions under the support of Hatch and State funds. 



1. A study of sucli animal diseases as occur in the State and come to 

 our attention through the State officials or the veterinarians and their 

 clients.
