DAIRY CATTLE 371 



3. Score a number of dairy cows, then weigh and test the milk 

 produced by each, and compare your judgment and that of the owner 

 of the cows with the record of performance. 



4. Visit dairy farms in your community. Make a record of the 

 milk and butter fat produced by each cow, how much the herd is fed, 

 and prepare a report showing whether any cows should be disposed 

 of and why, whether the system of feeding should be changed, and 

 whether the barn or yards can be improved.
