The figures in Table 8 show the relation between milk production 
and returns for $1 expended for feed and the relation between milk 
production and feed cost per 100 pounds of milk. This table is also 
a continuation of Table 6. 
In Group 2 the average milk production was 3,250 pounds, and 
the average returns for $1 expended for feed $1.64. In Group 9 the 
average milk production was 13,250 pounds, and the average returns

for $1 expended for feed $2.90. In Group 2 the average cost of feed 
for 100 pounds of milk was $1.54, and in Group 9 only $0.87. 
Figure 9 shows graphically the relation of milk production to 
returns for $1 expended for feed. 
The figure shows that the returns for $1 expended for feed in- 
creased rapidly though somewhat irregularly as milk production 
increased from Groups 1 to 9. The cows that averaged 12,000 pounds
