COST OF PRODUCING HOGS IN IOWA AND ILLINOIS 19 
- The average cost of 100 pounds gain for spring pigs after weaning 
was $4.17 in 1921 and $5.40 in 1922. The cost of gain for fall litters 
was $5.26 in 1921 and $6.37 per 100 pounds in 1922. The cost of 
gain for each year was approximately $1 Ae ed for fall pigs than for 
spring pigs. The greater cost of gain for fall pigs was due not only to 
larger quantities of feed and labor being consumed but to higher 
prices for the feeds. In 1921 the average farm price of corn was 32 
cents per bushel for the spring pigs and 41 cents for the fall pigs. 
In 1922, the price of corn having advanced, the average monthly farm 
price of corn was 53 cents for the spring pigs and 61 cents for the fall 
pigs. The feed cost was 66.3 per cent of total cost of gain for sprin 
pigs in 1921 and 79.1 per cent in 1922. The feed cost for the fa 
pigs was 76.4 per cent of total cost in 1921 and 81.8 per cent in 1922. 
A comparative itemized statement of the cost of 100 pounds gain after 
weaning for spring and fall litters is given in Table 12. The cost of 
producing the weanling pig must be added to the cost of gain after 
weaning to secure the gross cost of producing pork.

The total cost of gain after weaning for spring litters varied from 
$2.36 to.$6.94 per 100 pounds in 1921 and from $3.71 to $10.10 in 
1922.--The feed cost, exclusive of pasture, varied from $1.26 to 
$4.46 per 100 pounds in 1921 and from $2.44 to $5.60 in 1922. The 
total cost of 100 pounds gain for fall pigs after weaning varied from 
$3.86 to $8.66 in 1921 and from $4.31 to $8.37 in 1922. The feed 
cost of pork produced from fall pigs exclusive of pasture, varied from 
$3 to $6.36 per 100 pounds in 1921 and from $2.98 to $6.18 in 1922. 
The share of gain produced in the various cost groups within these 
extremes of variation is given in Table 13. In 1921 the bulk of the 
gain, 81.8 per cent of the gain made by the spring pigs on which 
records were obtained, was made at a cost between $3 and $5 per 100 
pounds. In 1922, the cost of 80 per cent of the gains were within 
the $4 to $6 range. About 72 per cent of the gains made by the fall 
pigs of 1921 cost more than $4 and less than $6 per 100 pounds; in 
1922 the cost of 85 per cent of the gain ranged from $5 to $8 per 100 
pounds.
