IRRIGATED FARMING IN TWIN FALLS COUNTY, IDAHO 47 
UTILIZATION OF LAND 
In obtaining the records it was necessary to drop some farms and 
add others from year to year, hence the variation in the number of 
farms during the four years (Table 26). The average size of these 
dairy farms was about 77 acres. This is approximately 4 acres larger 
than the average of the general crop farms. As would be expected, 
these farms had a much hi her percentage of the tillable land in pas- 
ture and alfalfa and a much lower percentage in wheat than had the 
general crop farms. |

DISTRIBUTION OF LIVESTOCK 
The different kinds of livestock kept and the number of animal 
units of each kind are shown in Table 27. There was an average of 
22 dairy cattle animal units per farm during the four years of the 
study. This is about five times the number kept on the general 
crop farms. This is the only striking difference in the livestock kept 
by the three types of farms.

1 In order to compare the livestock kept on the different farms, it is necessary to have a standard of com- 
parison. The standard here used is the ‘‘Animal unit.’”’ It is represented by one mature horse, mule, 
cow, or steer. Also by as many smaller animals as require the feed of one of these mature animals. Usually 
2 head of woe cattle, 2 colts, 5 hogs, 10 pigs, 7 sheep, 14 lambs or 100 chickens are considered equivalent to 
one animal unit,
