Staiion Findings voiih Dairy Herds. 



461 



The preceding table is especially valuable because it covers a 

 year's findings with all the cows of the herd, none being omitted 

 in order to raise the average. 



We observe a wide range in the cost of feed consumed by the 

 several cows, a still wider one in the yield of milk, and a marked 

 difference in the cost of producing milk and fat. It is apparent 

 from this table that even in well-nurtured dairy herds, where all 

 conditions are favorable, it is of the highest importance to study 

 feed consumption and the returns of milk and fat of each cow that 

 the poor ones may be eliminated and only the best reserved for 

 future breeders and producers. 



694. Dry matter required. — Another lesson from the Cornell 

 herd is here presented. The dry matter in the feed required for 

 producing one hundred pounds of milk and one pound of butter- 

 fat with each of the cows during seven months — November to 

 A.pril inclusive — is given in the following table:

 milk and one pound of fat — ComeU Station.
