Background

Straw is a generic term for the stem and leaf (ear) parts of mature crops. Typically wheat, rice, corn, potato, canola, cotton, sugarcane and other crops (typically coarse grain) remain after harvesting the seed. More than half of the photosynthesis products of crops exist in the straw, and the straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, is a renewable biological resource with multiple purposes, and is also a coarse fodder. Is characterized in that the crude fiber content is high (30% -40%), and lignin and the like are contained. Although lignin cellulose is not available to pigs and chickens, it is absorbed and utilized by livestock such as ruminants, cattle and sheep.
