BULLETIN 1069, U. S. DEPARTMENT OF AGRICULTURE. 
increased production is accompanied by increased income over cost 
of feed regardless of breed* age, iveight, date of freshening, or geo- 
graphical location. 
PRICES AND PROFITS. 
Several tabulations were made to determine, if possible, whether 
cows which were large producers of milk and butterfat are rela- 
tively more profitable or relatively less profitable when prices are 
high than when they are low. The results of such tabulations have 
so far been inconclusive, and for that reason the figures have been 
omitted. In every case of those studied, however, the low producers 
had a high feed cost per unit of production, low returns for $1 ex- 
pended for feed, and small income over cost of feed. In every case 
the high producers had a low feed cost per unit of production, large 
returns for $1 expended for feed, and a high income over cost of 
feed. 
RELATION OF MILK PRODUCTION TO INCOME. 
MILK PRODUCTION AND INCOME OVER COST OF FEED. 
Table 6 shows the relation of milk production to income over cost 
of feed in associations where the product was sold as whole milk. 
The results are much the same as those obtained from associations 
where the income was from the sale of butterfat.

was sold as whole milk; years 1915 to 1920. inclusive — From 3.220 yearly
