REPOKT OF EXTENSION WORK IN DAIRY HUSBANDRY. 



BY J. A, WALDRON^ A. C. RALTZER^ H. E. DENNISON. 



Dairy extension work during the p^ast year has been carried forward 

 along somewhat different lines than in the past. In addition to the reg- 

 ular work of organizing and supervising cow testing associations, a pure- 

 bred sii^ train was operated during August in co-operation with the 

 Michigan Holstein-Friesian Association, and the Michigan Central and 

 Pennsylvania Railroads. Intensive county dairy and alfalfa campaigns 

 were also put on during the winter in place of the extension schools 

 fonnerly held. These campaigns have proved very effective and the 

 concentrated effort put forth in this way has resulted in a number of 

 new cow testing associations with prospects for more, as well as for a 

 number of co-operative bull associations. It is felt that these associations 

 bring home to the fanner the principles of better dairying in ta way that 

 assures their daily application. The purpose is not increased production, 

 but more efficient production. 



More help has been given this project than in the past, A. C. Baltzer 

 and J. A. Waldron have been emploj-ed full time, except for four moutJis 

 during the winter when the latter was unable to do field work because 

 of ill health, H. E. Dennison has been giving full time to the project 

 since December 1st and Prof. O. E. Reed and S. J. Brownwell of the 

 Dairy Department have given especially valuable help at several differ- 

 ent short periods during the year.
