MISSOURI AGRICULTURAL REPORT. 



heifer may do very poorly for the first year. In such cases, the heifer's 

 individuality together with her breeding should be considered before 

 she is sold. The testing of cows should, however, be carried on in 

 every dairy if a systematic selection is to be made. A good cow seldom 

 has two "off years" in succession. 



In closing let me present a few tables comparing the result of differ- 

 ent cows and herds, and also comparing the first and second year's work.

Table 2. — Giving average record of the cow producing the most 

 butter fat of all the cows tested, for two years and average record of the 

 cow producing the least butter fat: 



Pet of herd "N" gave for the two years an average of 2,630 pounds 

 more milk. 232 pounds more butter fat, and 270 pounds more butter, 

 per year than Joe's Birde of herd "F," 



Pet of herd "N" has the highest average record of all the cows 

 tested and Joe's Birde of herd "F," the lowest.
