of this seed is put in many commercial scratch feeds. It not only 
adds variety to the ration, "but also increases "both the protein 
and fat content of the scratch. feed and is considered especially 
desirable for use during the molting period. Although much higher 
in protein and fat than either corn or wheat, sunflower seed is 
usually relatively too high in price to make up more than a small 
percentage of poultry feed... 
"The lack of a sustained active demand for sunflower seed has 
"been reflected in prices of this seed during the last 8 years. 
Growers in. Illinois and Missouri have received an- average price of 
2 1/10 cents a pound during the 10-year period, 1930-39, and growers 
in California received 2 4/5 cents... There seems to be no dispo- 
sition on the part of poultry-feed manufacturers to increase the 
percentage of sunflower seed in their feeds... 
"Sunflower seed weighs from 21 to 26 pounds per bushel and con- 
tains from 2° to 32 percent of oil that can be used for food or for 
technical purposes... In the United States there has been no sus- 
tained commercial production of sunflower oil. In 1920 about 100 
tons of seed were crushed in a cotton-oil mill in Tennessee, hut 
this operation was not repeated in subsequent years. It is rejDorted 
that seed could not be obtained at a price that would permit a 
profit to the mill... 
"luring the 5-year period, 1932-35, a total of 120,000,000 pounds 
of sunflower- oil was' imported, of which about 75 percent was desig- 
nated as edible oil. In 1937 only 172,000 pounds of the oil desig- 
nated as edible were imported. The following year only a few thou- 
sand pounds came in, and there was no edible sunflower oil imported 
during 1939. The largest quantity was imported in 1935 when 
37,250,000 pounds were received, less than 1 percent of which was 
designated as inedible oil."

Sunflower oil industry in Cuba. Soap 7(ll): 116. Nov, 1931. 307.8 Sol2 
Discusses the project of an "American Company" for the develop-' 
ment of the sunflower oil industry in Cuba. The first sowing was 
of approximately 9,000 acres. The aim is to develop the Cuban market 
"by selling sunflower oil at a price based upon the market price of 
prime summer yellow cotton seed oil plus the cost of freight to Cuba 
and a certain part of the difference due to improved quality." This 
is expected to benefit the cattle industry as a whole.
