1 Totals of droves and pounds of gain. 
The average amount of labor required during 1921 and 1922 per 
100 pounds gain was 0.93 hour of man labor and 0.32 hour of horse 
labor for the spring pigs and 1.43 hours man labor and 0.53 hour 
horse labor for the fall pigs. Veterinary, vaccination, medicine, and 
other costs were 27.2 cents per 100 pounds for the spring pigs and 
18.9 cents for the fall pigs. Other miscellaneous costs were 13.1 
cents for spring pigs and 16.3 cents for fall pigs per 100 pounds gain. 
The average amounts of feed, pasture, and labor consumed by 
spring and fall pigs when grown to different weights are given in 
Table 15. This table shows that there is a regular increase in grain 
consumed when pigs are fed to heavier weights and also the heavier 
grain requirement of fall pigs compared with spring pigs of similar 
weight. The quantity of corn consumed by the class of spring pigs 
averaging 125 pounds in weight was 294.3 pounds, and by the class 
averaging 275 pounds the corn consumption was 405.2 pounds. 
5 An animal unit of hogs is the equivalent of hogs in other livestock. The animal units were computed 
each month and the actual number of days on pasture determined. Since swine can not handle roughage 
as well as ruminants do, the following schedule adapted from data by the department of farm organization 
and management of the University of Illinois was used in converting the hogs into animal units instead 
of the 5 sows or 10 pigs ratio frequently used:
