In feeding concentrates, not as much difference was made in the 

 quantity given to low yielding and high yielding cows as would have 

 been made had the production per cow been used as the basis of 

 compounding the ration. The difference, however, amounted to as 

 much as $13 per year in the value of concentrates fed to individual 

 cows. The mixture of concentrates, for the most part, consisted of 

 sucrene and corn-and-cob meal. Some brewers' grains, gluten 

 feeds, cottonseed meal, and dried beet pulp, were used. The dry 

 roughage consisted of corn stover, alfalfa, and mixed hay, and wheat 

 straw for bedding. The variation in total quantity from year to 

 year is due largely to the difference in the quantity of corn stover. 

 Although the quantity of silage varies somewhat from year to year, 

 the average is about four tons per cow per year. The pasture 

 season was increased each year by making greater use of the after- 

 math on hay meadows. The average price per ton of concentrates 

 for the four years was $24.38, $26.60, $25.10, and $23.78, respectively, 

 the average per year being $24.95. The average price per ton of 

 all dry roughage varied from $6.60 to $10.40, the average per year 

 being $8.65. The charge made for silage varied from $3.83 to $5 

 per ton, the average per year being $4.64.
