Crop residues and their processing methods to improve their nutritive value
|
- The leftover portion of the crop after the main crop is harvested for human consumption is called as crop residues.
Crop residues may be grouped under the following headings
Straws
|
Stovers
|
Aerial portion of other crops
|
Others
|

Nutritional quality of crop residues
- Low in crude protein, calcium, carotene and available energy.
- High in cell wall constituents, lignin and silica
- Reduced palatability – low voluntary intake
- Low digestibility of dry matter and bioavailability of energy
- Bulky in nature
