WINTER RATIONS AND PASTURE GAINS OF CALVES.

The foregoing figures are based on the average farm prices from 
1910 to 1919 as given in the Yearbook of the United States Depart- 
ment of Agriculture for the States of West Virginia, Virginia, Man- 
land, Pennsylvania, Ohio, Kentucky, Tennessee, and North Carolina. 
When one wishes to determine which ration should be used in a par- 
ticular feeding operation, it is suggested that he apply local prices to

Fig. 8. — Annual results of winter and summer (grass) feeding for Lot 3. These calves 
were fed the following ration during the winter periods : Mixed hay, 9.2 pounds ; grain 
mixture, 2.6 pounds. 
the average amounts of the feeds consumed per calf, as given in 
Table 4. 
COST PER POUND OF GAIN. 
From Table 8 it will be noted that the winter cost constitutes ap- 
proximately two-thirds of the total cost for the year. Most of the 
gain, however, is made during the summer or pasture season. Hence, 
the cost of wintering becomes the chief factor governing the cost of 
a pound of gain.
