Rice Straw
Oryza sativa
Also known as: Paddy straw
About Rice Straw
Vegetative part of paddy crop after removal of grains, with low palatability.
Nutritional value and use in livestock rations
Rice Straw is a roughage (forage) and an energy source in the Pakistan Feed Library. On average rice straw contains crude protein 5.5% of dry matter, metabolisable energy 1.7 Mcal/kg, TDN 47.9% of dry matter, NDF 66.5% of dry matter.
Energy-yielding forages and crop residues supply fibre and energy at a low cost. They are normally balanced with protein sources, minerals and, where needed, concentrates so that animals receive complete nutrition.
Nutrient values vary with variety, growing conditions, processing and storage, so treat the averages as a guide. Send us your ration details if you would like advice on using it in a TMR.
TMR Pakistan supplies related feed ingredients in bulk for farms and feed mills. See the matching products or contact us for a quotation.

- Literature values
- Laboratory analysis
- Calculated from lab data
SD = standard deviation DM = dry matter. Nutrients other than dry matter are expressed on a dry-matter basis. TDN = total digestible nutrients; ME, NEm, NEg, NEl and DE = metabolisable, net (maintenance / gain / lactation) and digestible energy.
