increase in milli and butter fat was largely due to better system of feed- 

 ing during tlie second year. There were, however, a few new cows in 

 the second year, and a few of the poor cows were sold at the end of 

 the first year. This change, of course, had something to do with the 

 increased yield of the herd. There were still a few cows kept upon this 

 farm that were so poor that the owner would not enter them in the test. 

 Record for cow No. 6 for two years, and her average production for 

 that period: 



Yearns Age, Date of Milk, Fat, Per Fat, Butter, Days in 



Work. Years. Breed. Calving. Pounds. Cent. Pounds. Pounds, ^filk. 



First 3.5 Native 5/29/'02 1,838 4.43 ■ 81 95 210 



Second ..4.5 Native 5/4/'03 3,624 3.84 139 162 238 



Average for two years 2,731 4.02 110 128 224 



Cow No. 6, the poorest animal in herd A, in two years gave 5,462 

 pounds of milli and 220 pounds of butter fat. A good daily cow should 

 produce as much in one year as three animals of this kind. 



Record of cow No. 10 for two years and her average production for 

 that period: 



Year's Age, Date of Milk, Fat, Per Fat, Butter, Days in 



Work. Years. Breed. Calving. Pounds. Cent. Pounds. Pounds. Milk. 



First 4 Native 3/5/'02 3,833 3.37 129 150 245 



Second 5 Native 3/l/'03 3,553 3.55 126 147 298 



Average for two years 3,693 3.45 128 149 272 



The average of cow No. 10 is very low. Why she produced more milk 

 and butter fat in the tirst j'ear's tost than in the second, when a better 

 ration was fed, can not be intelligently answered. 



Record for cow No. 15 for two years and her average production for 

 that period: 



Date of Milk, Fat, Per Fat, Butter, Days in 



Calving. Lbs. Cent. Lbs. I^bs. Milk. 



ll/4/'01 6,145 3.63 223 260 294 



ll/15/'02 6,874 3.87 266 310 273 



Average for two years 6,510 3.70 245 285 283 



Cow No. 15, which was the best animal in herd A, gave considerably 

 more milk and butter fat in the second year's test than she did in the 

 first. Her increased yield seemed to be entirely due to a better system of 

 feeding.
