SUCCESSFUL FARMING 



In Jefferson County, N. Y., the receipts per cow from the best farms were 

 56 per cent more than the average. In these same counties the receipts 

 per acre on best farms exceeded that of the average by a much smaller 

 margin. This indicates that the degree of intensity may be carried further 

 with cows than it can be with crops. 



Relation of Cows to Size of Farm. — The number of dairy cows that 

 may be maintained on a farm will depend on the productivity of the land, 

 the feeding system best adapted and the proportion of the total feed that 

 is to come from the farm. It will also depend on the extent to which cash 

 crops may be grown. 



Knowing the average yield of the crops to be grown for the dairy and 

 having a feeding system for the year, it is possible to calculate just how 

 many cows may be maintained on the farm, and just what acreage of the 

 several crops will be required. Such a problem is worked out and pre- 

 sented herewith. 



How many cows can be kept on a 110-acre farm when the yields of 

 crops and the feeding system are as follows: 



Yields: 



Pasture, one acre for each cow and bull. 



Soiling corn, 7 tons per acre. 



Silage corn, 10 tons per acre. 



Corn for grain, 50 bushels per acre = 1.4 tons. 



Oats for grain, 50 bushels per acre = 0.8 ton. 



Wheat for grain, 26§ bushels per acre = 0.8 ton. 



Hay, 3 tons per acre. 



Feeding System: 



Five horses, one for delivery and four for work. 

 365 days at 15 pounds hay each daily. 

 365 days at 10 pounds grain each daily. 

 Grain, one-half oats and one-half corn. 



Cows and One Bull, Daily Requirements of Each. 



Grain for cows and bull, 3 parts corn, 2 parts oats, 5 parts purchased concentrates. 

 Wheat sold. Acreage equal to acreage of oats. 

 Oats and wheat straw for bedding. 



Acres of Each Crop. — From the food requirements calculate the 

 amount of each crop required for the year for each cow and for the five 

 horses. This is expressed decimally in tons and entered in the first and 

 second columns of the following table. The figures are obtained by mul-
