THE COST OF KAISING A DAIRY COW. 
upon pasture. (Fig. 1.) The feed cost per calf for the first month, 
as shown in Table III, is in reality too high. This is caused by there 
being a much larger number of calves fed exclusively on whole milk 
during the latter part 
of the month. As 
shown in this table, 
there is an average of 
only 6.3 head for the 
whole month, while 
there actually were 
only 1 or 2 at the be- 
ginning and 18 at the 
end. The fact that 
the calves are fed 
whole milk for only 
about two weeks 
makes the cost per 
head appear too high 
for the month. Where 
the numbers remain 
fairly constant, as 
they do after the first 
month, the monthly 
averages per head are 
true weighted averages. However, the sum of these monthly aver- 
ages can not be expected to agree exactly with the weighted averages 
for the year.

summer months the calves are on pasture. This is rep- 
resentative of the size and condition of the calves at 
this age on the Brigham farm.

The yearly totals show that the whole milk represents 21.3 per 
cent of the feed cost, while the skim milk represents 25.7 per cent.
