FIFTY-FIRST ANNUAL CONVENTION 163 



barn for his cows. We have found in several instances 

 where the herds showed an increased production in milk 

 of from 10 to 14% without changing the grain ration and 

 roughages fed after the drinking cups were installed. Every 

 farmer should have a store house for winter feed. 



Without a silo he cannot bring about economical pro- 

 duction. I believe that a 20-cow herd can pay for a silo in 

 two years through increased production in milk. I do not 

 know of any tendency growing in this state to stop building 

 silos, because of the high labor cost in filling them or be- 

 cause of the high value of alfalfa or other legumes. There 

 is no better roughage combination for the dairy herd than 

 alfalfa and silage. — A. J. Cramer, Dairy Husbandman, Wis.

Washington Tests 10,000. 



Those of us who are doing the dairy work in the Ex- 

 tension Service of the State College are doing whatever we 

 can to assist the dairymen in securing modern equipment. 



We have about 10,000 cows in 10 associations. It 

 seems to me that we must use just as good methods as are 

 used by dairymen in foreign countries if we are to compete 

 wiht them in the dairy markets of the world. If the Dan- 

 ish and the Dutch continue to use the Cow Testing Associ- 

 ations as efficiently as they have been using them, it will 

 be necessary for us to do likewise, in order to compete. 



It seems to me that it is quite practical to put every 

 cow through the Cow Testing Association. The Cow Test- 

 ing Associations in this state are organized in such a man- 

 ner that a man with five cows can test as easily as the man 

 with 50 cows. — Don G. Magruder, Extension Specialist in 

 Dairying, The State College of Washington.
