aminoacids, was determined. NP showed high dry basis content of proteins (24%) and nitrogen-free extract (32%), whereas crude fiber concentration was low (8.4%). Also, NP showed high concentrations of ash (29%), and mineral, specially for calcium (1.65%) and zinc (20 mg/100g of NP). Additionally, glutamic and aspartic acids, as well as leucine, were the major types of aminoacids found in NP. In conclusion, though nettle
plants are an under-utilized resource, the elevated content of protein found in powders prepared from their leaves might become a compelling reason to include them as a protein supplement in animal diets.
Highlights
- Potential supplement for animal feed from nettle-leaves (Urtica urens).
- Re-use of a weed by a simple process of drying and grinding.
- The high content of proteins and minerals such as calcium and zinc.
- Amino acid profile with a high content of glutamic and aspartic acids, leucine and proline.
- Fatty acid profile with a predominance of polyunsaturated fatty acids, such as α linolenic and linoleic acids.
