SOME IMPORTANT FACTORS IN SWINE PRODUCTION ON 
IRRIGATED LANDS. 
On nearly every irrigation project in the United States it is pos- 
sible to produce pork in commercial quantities. Swine growing has 
proved to be one of the industries through which the irrigation 
farmer can utilize certain of his field crops advantageously. The im- 
portance of this industry in irrigated districts fluctuates widely from 
year to year in response to various changes in economic conditions. 
One of the most important economic factors influencing swine pro- 
duction in these regions is the relationship between the prices of feeds 
and the prices of pork. Frequent changes in this relationship have 
resulted in great instability in the swine industry on irrigated lands 
and this has led to much economic loss.
