The grains contain more fat than straw or hay. Hay is usual- 

 ly higher in fat than straw. A certain class of seeds such as 

 cotton seed, peanut, rape, sunflower, and flax seed are important 

 for their high oil content. The oils from some of these seeds, 

 notably the oils from cotton seed and flax seed, are expressed 

 by hydraulic pressure or extracted with some solvent, and sold 

 to us as cotton seed oil, cottolene, linseed oil and similar products.
