About Maize Cobs
A less palatable byproduct of maize crop, the central fibrous portion of maize ear.
Nutritional value and use in livestock rations
Maize Cobs is a roughage (forage) and an energy source in the Pakistan Feed Library. On average maize cobs contains crude protein 3.7% of dry matter, metabolisable energy 1.9 Mcal/kg, TDN 58.7% of dry matter, NDF 80.1% 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.

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.
