portauce to tlie breeders of pure bred dairy cattle in Michigan. It is 

 pleasing to note that in spite of war conditions the number of official 

 seven day tests conducted in the State has increased 17.8 per cent during 

 the last live years. It is also a matter of satisfaction to find that the 

 amount of butter fat produced by Michigan cows, as shown by these 

 seven day tests, has increased from an average of K^^^~^ pounds of fat in 

 1!)(IS to iS.-il jxjunds in the year ending June '.\0, 1!)2(). This is an in- 

 crea.se of 20.;> i)er cent. Undoubtedly this increase is due to better 

 knowledge of breeding and feeding obtained through these tests. 



Tlie senii-!;fticia,l or yearly testing has also increased markedly in the 

 past year. During llie year ending June :{(), 11)10, there were 250 Vows on 

 test in the three leading bi*eeds in the State, Jersey, Guernsey and Hol- 

 stein-Fi'iesian. During the year ending June 30, 1920, there were 437 

 cows tested in these same three breeds, an increase of (51.4 percent. 



If it had ))een p(tssil»le to secure more help on the farms and more men 

 to act as supervisors, the increase in l)oth ilivisious of this work would 

 liave been greater. 



DAIRY BARN. 



As noted a])ove some experimental Avork was carried on at the dairy 

 barn. Other notable e\ents during the year was the development of 

 Bravura 3d, a Brovxii Swiss cow that produced 12,018.4 pounds of milk 

 containing 558.444 pounds of butter fat, thereby breaking the world's 

 record for breed and age. College Belle Butter Lass, a IIolstein-Friesian 

 cow, ])roduced 25,070.2 pounds of milk containing 1112.05 pounds of 80 

 ]»ercent buttej- in a yearly test. This COAV was later sold for |3,250.00 at 

 l»ublic auction.

 Crops O-Crop Adaptation and ICxperimental Methods, and Farm Crops 

 4-B-Advanced Ceuctics. Tiie elementary Forage Cro])S course (Farm 

 Cro])s 2) was given, for the tirst time, as a combined laboratory and 

 lecture course. Advanced woik in grain standardization was given as 

 l)art of courses 5 and (». an.d a fidl equipmeut of grain standardization

 was increased, an<l the liialerial used for instructional and 4lisplay

The fall and spring crops courses were sui)ported by more frequent 

 field trips tlian previously. Carefully prepared lantern-slide lectures have
