What is straw?

Straw is the general term for the stems, leaves (ears) of mature crops. Usually refers to wheat, rice, corn, potatoes, rape, cotton, sugar cane and other crops (usually coarse grains) after harvesting seeds.

More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by high crude fiber content (30%-40%) and high lignin content. Lignocellulose can not be utilized by pigs and chickens, but can be absorbed and utilized by ruminants, cattle, sheep and other domestic animals.
