These tables are good examples of the milk and butter fat yield of all 

 :he cows at different times during the test. They clearly show that the 

 ;ows were not persistent milkers. The individuality of the cows, the poor 

 leeding which they received, undoubtedly caused the rapid decline in milk 

 ind butter fat production from one period to the next and their short 

 Deriod of lactation. 



The cows gave more milk and butter fat in the August test than they 

 3id in July. This was probably due to the fact that the cows were taken 

 'rom a poor wood pasture the last of July and put into a good clover 

 pasture.

It is perhaps well to compare the performance of eight of the poorest 

 cows as well as eight of the best cows kept in different herds, and also 

 compare the average production and profit of each herd tested. This is 

 done to show the great differences, even among the poorest and best cows, 

 and also the difference in production and profit between herds of cow* 

 kept upon the farms of Illinois.
