Available in black or grey stripe varieties.
Sunflowers (Helianthus annus) are grown throughout Australia for the production of seed for oil extraction. Sunflower seed is also grown for birdseed and sometimes a small amount is available for use as a stock feed.
The whole seed contains about 15 percent protein with an energy level equal to that of the cereal grains. Its main advantage is the high fat levels, providing a good source of linoleic acid.
Its main disadvantage is that it has a high husk level that will limit its use in diets for pigs.
